Job Overview
This chapter qualifies you to apply one approved basic texture system to a controlled practice wall or room and produce a uniform, matched pattern ready for paint. The finished work product is one textured wall or room surface that matches an approved sample panel, plus the recorded mix, equipment settings, and inspection results that document how that match was achieved.
You will select the approved texture option from the finish schedule; confirm the drywall is primed or otherwise prepared as the texture system requires; mix a small batch and produce a sample panel; adjust equipment settings until the sample matches the approved standard; apply the texture with consistent distance, angle, overlap, and travel speed; blend passes while the material is still workable; knock down peaks where the system calls for it; and inspect the finished pattern under raking light for thin spots, heavy spots, lap lines, runs, contamination, or inconsistent knockdown.
Texture is optional under the approved finish schedule. This chapter assumes the schedule calls for orange peel, knockdown, or another named basic texture; where the schedule calls for a smooth finish instead, the same sample-matching and application-control skills are demonstrated on a practice panel rather than on the finished room. Chapter 15 primer inspection must be complete and approved before this chapter begins, and this chapter's approved surface is the condition Chapter 20 expects when the capstone room reaches its texture stage.
Skills You Will Demonstrate
- DW-091 — Prepare the surface for texture.
- DW-092 — Mix texture material.
- DW-093 — Apply orange-peel or knockdown texture.
- DW-094 — Maintain a consistent pattern.
- DW-095 — Blend edges.
- DW-096 — Inspect texture quality.
Where This Skill Fits
Texture is the last material applied to the drywall surface before paint, and it is the least forgiving to correct after the fact. A pattern that is too heavy, too light, inconsistent in density, or poorly blended at a boundary will telegraph under every future raking light and under every coat of paint. The sample-panel discipline you practice in this chapter — mixing a small batch, testing settings, adjusting one variable at a time, and only then committing to the wall — is the same discipline that prevents an entire room from being redone.
This chapter depends directly on Chapter 15's primed and approved surface, since texture applied over unprimed or improperly cleaned drywall will absorb unevenly and telegraph joint lines. The equipment-control skills here — spray distance, angle, overlap, and travel speed — also apply directly to Chapter 17 through 19 repair work, where matching existing texture on a patch is one of the required repair competencies.
Scope and Intended Use
This chapter covers:
- selecting the approved texture option from the finish schedule
- confirming surface preparation, primer condition, and environmental limits before mixing texture material
- mixing a small test batch and producing a sample panel matched to the approved standard before wall application begins
- applying orange-peel or knockdown texture using controlled equipment settings
- maintaining a consistent pattern across field areas and boundary transitions
- blending texture at repair or boundary edges
- knocking down peaks for a knockdown finish using a controlled blade angle and set time
- inspecting the finished texture under normal and raking light and correcting localized defects
This chapter does not authorize the learner to:
- select or invent a texture pattern, mix ratio, or equipment setting that is not specified by the approved finish schedule or the texture-product manufacturer's instructions
- apply texture over drywall that has not passed the Chapter 15 primer inspection, or over an unresolved moisture, mold, or contamination condition
- operate a compressor or spray equipment that has not passed the pre-use inspection required in Step 6 below
- claim a finished texture matches an approved standard without producing and approving a sample panel first
Any condition outside the learner's qualification, including a texture-product compatibility question or an equipment malfunction, must be referred to the manufacturer's instructions, a qualified equipment technician, or the responsible supervisor.
Reference Conventions
Establish these references before any texture is mixed or applied.
| Term | Definition |
|---|---|
| Orange peel | A fine, stippled spray texture applied and left as-sprayed, without a knockdown step |
| Knockdown | A spray texture that is partially flattened with a blade after a controlled set time, producing a mottled, flattened-peak pattern |
| Sample panel | A small test application of texture, produced under the planned settings and compared to the approved standard before field application begins |
| Approved standard | The physical sample, photograph, or manufacturer reference identified by the finish schedule that the finished texture must match |
| Set time | The interval between spraying knockdown texture and flattening it, during which the material stiffens enough to be knocked down without smearing |
| Boundary edge | The line where new texture meets an existing textured surface, an untextured surface, or a repair area, and where feathering is required to avoid a visible seam |
Texture Application Record
Before mixing any texture material, record the following directly on the texture application worksheet:
Room or wall system: ______ Approved texture option: ______ Approved standard reference: ______
Date started: ____________ Applicator name: ____________
Prerequisites
- An approved Chapter 15 primer inspection for the room or wall system, with no unresolved defects
- The approved finish schedule identifying the texture option, material, mix ratio, equipment settings, and approved standard for the room or wall system
- Confirmation that room temperature and humidity are within the texture product's stated application range
- Access to a hopper gun, compressor, mixing tools, knockdown blade, and sample board in serviceable condition
- Established ventilation and overspray containment for the work area
Common Field Fundamentals
Every texture application in this book follows the same sequence regardless of pattern: confirm surface readiness, protect adjacent surfaces, mix a small batch, produce and approve a sample, record the approved settings, apply with controlled distance and speed, blend and knock down as required, and inspect under raking light before removing protection.
PreparationPrimer condition, protection, ventilation, equipment inspection
Sample matchingSmall-batch mix, test panel, one-variable adjustment, approval
ApplicationDistance, angle, overlap, travel speed, blending
InspectionRaking light, thin and heavy spots, lap lines, contamination
Sample Matching Before Field Application
Do not apply texture to the finished wall or ceiling until a sample panel produced under the planned settings has been compared to and approved against the finish schedule's approved standard. Adjust only one variable — pressure, distance, nozzle size, or pass speed — between attempts, and record the settings that produced the approved match before proceeding.

Texture Application
Basic Wall Texture Application
A. Finished-Project Specification
Scope: one complete texture application covering every primed wall or ceiling surface in the designated room or practice area that the approved finish schedule identifies for texture, using the specific option named in that schedule.
B. Texture Option Schedule (Component Schedule)
| Option | Application Method | Finishing Step | Approved Standard Source |
|---|---|---|---|
| Orange peel | Spray application with hopper gun at product-specified pressure, nozzle, and distance | None; left as-sprayed after drying | Finish schedule sample or manufacturer reference |
| Knockdown | Spray application as above, followed by a controlled set time | Flatten peaks with a knockdown blade at the controlled angle and pressure | Finish schedule sample or manufacturer reference |
| Other specified basic texture | As named and described by the approved finish schedule | As named and described by the approved finish schedule | Finish schedule sample or manufacturer reference |
Complete only the option named in the approved finish schedule for this room or wall system. Do not substitute a different texture option and do not mix application methods within one continuous surface.
C. Material Takeoff
- Texture material: premixed or powder compound as specified by the approved finish schedule, in the quantity required for the surface area plus the manufacturer's stated waste allowance.
- Mix water: clean water added only to the product-stated ratio; do not exceed the stated water-addition limit.
- Protection materials: sheeting and tape sufficient to cover all floors, ceilings, trim, fixtures, doors, windows, vents, and adjacent untextured surfaces in the work area.
- Sample-panel stock: one primed sample board or an inconspicuous primed area sufficient for repeated test applications.
D. Equipment Setting Schedule
| Variable | Starting Point | Adjustment Rule |
|---|---|---|
| Nozzle size | Manufacturer-specified size for the selected texture option | Change only if the sample pattern is too fine or too coarse compared to the approved standard |
| Air pressure | Manufacturer-specified pressure for the selected texture option | Change only if the sample pattern is too heavy or too light compared to the approved standard |
| Spray distance | Manufacturer-specified distance for the selected texture option | Change only if the sample pattern density is uneven compared to the approved standard |
| Pass speed | Manufacturer-specified travel speed for the selected texture option | Change only if the sample pattern shows thin or heavy streaking compared to the approved standard |
Adjust only one variable between sample attempts. Record the final approved combination of nozzle size, pressure, distance, and pass speed on the texture application worksheet before beginning field application.
E. Reference Conventions
Use the orange peel, knockdown, sample panel, approved standard, set time, and boundary edge definitions given in the Reference Conventions table above for every entry on the texture application worksheet.
F. Acceptance Standards
| Check | Standard |
|---|---|
| Surface preparation | Drywall has passed the Chapter 15 primer inspection with no unresolved defects, and is dry, clean, and free of contamination before texture is mixed |
| Sample panel match | The sample panel produced under the planned settings is compared to and approved against the approved standard before field application begins |
| Pattern consistency | Density, pattern size, and knockdown flattening are consistent across all field areas and boundary transitions, as viewed under normal and raking light |
| Boundary blending | No visible seam, ridge, or density change at any boundary edge between new and existing texture, or between texture and an untextured surface |
| Surface defects | No thin spots, heavy spots, lap lines, runs, contamination, or inconsistent knockdown remain uncorrected |
| Drying | Texture is fully dry before protection is removed or paint is applied, per the product-stated drying time |
G. Preparation and Protection Procedure (Steps 1–6)
- Select the approved texture option: orange peel, knockdown, or another specified basic texture. Confirm the selection against the approved finish schedule for the room or wall system.
- Review surface preparation, primer requirements, material, water ratio, equipment, nozzle, pressure, working time, and sample standard. Record each value on the texture application worksheet before proceeding.
- Confirm that the drywall is primed or prepared as required by the texture system. Verify the Chapter 15 primer inspection is approved for the surface with no unresolved defects.
- Protect all floors, ceilings, trim, fixtures, doors, windows, vents, and adjacent untextured surfaces. Seal sheeting edges to prevent overspray migration into adjoining rooms.
- Establish ventilation and overspray containment. Confirm ventilation will not backdraft a combustion appliance in or near the work area.
- Inspect the hopper gun, compressor, spray equipment, mixing tools, and electrical supply. Confirm hoses, fittings, and cords are free of damage before connecting power or air.
H. Sample Matching Procedure (Steps 7–10)
- Mix a small batch according to the product instructions. Do not exceed the product-stated water-addition limit.
- Produce a sample panel using the planned nozzle, pressure, distance, and pass speed. Apply the sample on the sample board or an inconspicuous primed area.
- Adjust only one variable at a time until the sample matches the approved standard. Use the Equipment Setting Schedule in Section D to guide each adjustment.
- Record the selected settings and mix. Enter the approved nozzle size, pressure, distance, pass speed, and mix ratio on the texture application worksheet before field application begins.
I. Field Application Procedure (Steps 11–18)
- Apply texture beginning at a controlled edge or corner. Start at the location identified in the finish schedule or, where none is specified, at the least visible corner of the room.
- Maintain consistent spray distance, angle, overlap, and travel speed. Use the approved settings recorded in Step 10 without deviation.
- Blend passes while the material remains workable. Overlap each pass into the previous pass before the material begins to set.
- For knockdown, allow the specified set time. Do not begin knockdown before the material has stiffened to the product-specified condition.
- Knock down peaks using a clean blade at the controlled angle and pressure. Wipe the blade clean between passes to avoid dragging material.
- Maintain consistent pattern across field areas and transitions. Compare the developing pattern to the approved sample at intervals during application.
- Feather texture at repair or boundary edges. Reduce density gradually into any adjoining existing texture to avoid a visible seam.
- Stop and clean equipment before material hardens. Do not allow texture material to set inside the hopper gun, hoses, or mixing tools.
J. Inspection and Documentation Procedure (Steps 19–22)
- Inspect under normal and raking light for thin spots, heavy spots, lap lines, runs, contamination, or inconsistent knockdown. Walk the full surface with a raking light source held close to the wall.
- Correct localized defects using the approved scrape, recoat, or blend method. Match the correction to the surrounding pattern before it dries.
- Allow the texture to dry before removing protection or painting. Confirm the product-stated drying time has elapsed.
- Document product, mix, equipment settings, sample approval, and final inspection. File the completed texture application worksheet with the room's project records.
Common Texture Inspection
Inspect every textured surface using the same checks regardless of pattern or room size.
- Preparation check: confirm the surface passed Chapter 15 primer inspection and is dry, clean, and free of contamination.
- Sample check: confirm a sample panel was produced and approved against the finish schedule's standard before field application began.
- Pattern check: confirm density and pattern size are consistent across field areas and transitions under raking light.
- Boundary check: confirm no visible seam remains at any boundary between new and existing texture.
- Defect check: confirm no thin spots, heavy spots, lap lines, runs, contamination, or inconsistent knockdown remain uncorrected.
- Drying check: confirm the texture is fully dry before protection is removed or paint is applied.

Failure Points and Troubleshooting
Cleanup
Clean all equipment and the work area only after the texture has fully dried and the final inspection is complete.
- Disassemble and clean the hopper gun, hoses, and mixing tools before texture material hardens inside them
- Remove protection sheeting and tape only after the texture is fully dry per the product-stated drying time
- Sweep and vacuum any dried overspray debris from floors and adjacent surfaces
- Store remaining texture material, sample boards, and equipment per manufacturer instructions
- File the completed texture application worksheet with the room's project records alongside the Chapter 15 primer inspection record

Skill Check
- Why must a sample panel be produced and approved before texture is applied to the finished wall or ceiling?
- Why should only one variable — pressure, distance, nozzle size, or pass speed — be adjusted between sample attempts?
- What surface condition must be confirmed before texture material is mixed, and which prior chapter's inspection establishes that condition?
- Why must knockdown material reach the product-specified set time before it is flattened with a blade?
- How is a visible seam at a boundary edge avoided, and how is one corrected if it appears?
- Why must ventilation and overspray containment be checked against nearby combustion appliances before spraying begins?
- What must happen to spray equipment before texture material hardens inside it?
- Why must the finished texture be inspected under raking light rather than normal room light alone?
- Under what circumstance may a smooth-finish project omit texture from the finished room, and what must the learner still demonstrate?
- Why must the approved mix, equipment settings, and sample approval be recorded before field application rather than only after the work is complete?

|---|---|---|---|---|
Total defects identified: ____________ Total corrected and reinspected: ____________
Final texture decision: ______ (Approved / Conditional / Rejected) Date: ____________ Applicator name: ____________
Performance Check
With application complete and the texture fully dry, review the surface against the Acceptance Standards table and confirm that the surface was primed and approved before texture began, the sample panel was produced and approved before field application, pattern density and size are consistent across all field areas and boundary transitions under raking light, no visible seam remains at any boundary edge, and no thin spots, heavy spots, lap lines, runs, contamination, or inconsistent knockdown remain uncorrected. Approve the finished texture only after every defect identified during inspection has been corrected and reinspected.
Project Closeout
You have completed the texture stage of the drywall finishing sequence. This chapter required you to prepare the surface for texture (DW-091), mix texture material (DW-092), apply orange-peel or knockdown texture (DW-093), maintain a consistent pattern (DW-094), blend edges (DW-095), and inspect texture quality (DW-096).
You now have a textured wall or room surface matched to the approved standard, with the mix, equipment settings, sample approval, and final inspection recorded on the texture application worksheet. That record is the controlling document for any future repair work in this room, since Chapters 17 through 19 depend on matching this exact texture when patching later damage.
File your completed texture application worksheet with the room's project records. Do not remove protection or schedule paint until the final texture decision on the worksheet is marked Approved, or Conditional with every remaining item corrected and reinspected.
