Directions for Earl’s Powder Putty
-
Surface prep: Ensure the area is clean, dry and sound. Remove loose material, dust, grease and contaminants. Key glossy surfaces for better adhesion.
-
Mix: In a clean container, add Earl’s Powder Putty and slowly incorporate clean water. Stir to a smooth, lump-free paste. Adjust water to suit the task.
-
Apply: Press the mix firmly into the repair with a putty knife or trowel. Slightly overfill to allow for sanding back flush.
-
Build: For deep repairs, apply in layers, allowing each to firm before adding the next.
-
Finish: Once dry, sand smooth. The cured filler can be carved or sawn to refine edges and profiles.
-
Coat: Prime/seal and paint after full dry. For exterior use, always seal with suitable coatings.
-
Clean-up: Clean tools with water while the product is still wet.
Dry and recoat times vary with temperature, humidity and film thickness. Allow extra time in cool or damp conditions and for deep fills.

FAQs – Earl’s Powder Putty
Can I mix a large batch and store it?
Mix only what you can use within the working time. Discard any mix that begins to stiffen or set.
Can I screw or nail into it?
For non-structural tasks, light fixings may be possible in sufficiently thick, fully cured areas. Pre-drill as needed and test first.
Is it paintable?
Yes. Once dry and sanded, prime or seal the repair and finish with your chosen coating system.
Always follow label directions. Test on a small, inconspicuous area to confirm compatibility and finish.
