Application Steps:
- Stir Thoroughly: Before use, stir the primer thoroughly to ensure a consistent mixture.
- Apply Evenly: Apply a uniform coat of primer using a roller, brush, or sprayer. Avoid over-application, which can lead to drips or uneven drying.
- Coverage: The primer covers approximately 350-450 square feet per gallon, depending on the porosity and texture of the surface. A 5-gallon pail covers approximately 2,000 square feet.
- Drying Time: Allow the primer to dry for approximately 3-4 hours before applying paint or hanging wallcoverings. Full cure time is 4 hours. The primer will dry with a clear-matte, tacky finish.
- Specific Applications:
- Torn Drywall: Apply directly over torn drywall to seal the exposed paper.
- Skim Coats/Joint Compound: Apply over dried skim coats or joint compound to ensure proper adhesion for subsequent layers.
- Residual Wallpaper Paste: Apply over cleaned surfaces with residual paste to seal and prepare for new wallcoverings.
- Popcorn Ceilings/Textured Walls: The primer's formulation helps prepare these surfaces for a smoother finish or better adhesion.

5. Maintenance and Storage
Cleanup:
Clean tools and equipment immediately after use with warm water and soap. Dried primer may require stronger cleaning agents or mechanical removal.

Store the product upright in its original sealed container in a cool, dry place. Protect from freezing. Freezing may damage the product and render it unusable. Ensure the lid is tightly sealed to prevent drying out.
6. Troubleshooting
- Problem: Primer not adhering properly.
Solution: Ensure the surface was thoroughly cleaned and dry before application. Remove any loose debris, dust, or grease. Allow adequate drying time for previous repairs (e.g., patching compound). - Problem: Uneven finish or streaks.
Solution: Apply the primer in thin, even coats. Avoid over-application. Ensure your roller or brush is fully saturated but not dripping. Stir the primer thoroughly before and during use. - Problem: Primer appears too thick or difficult to apply.
Solution: Ensure the product has been stored correctly and not exposed to freezing temperatures. Do not thin the product unless specifically instructed by the manufacturer. - Problem: Bubbling or blistering after application.
Solution: This can occur if the surface is not completely dry or if there is trapped moisture. Ensure the surface is fully dry and free of contaminants. For torn drywall, ensure all loose paper is removed and the surface is sealed properly.
