De-gloss the Surface
De-glossing the surface using sandpaper will help you achieve the best adhesion results.
Use a Stiff Putty Knife
Use a stiff putty knife to chip or scrape away any rough edges of the repair to create a smooth surface.
Use a Flexible Putty Knife
Using a flexible putty knife to apply filler will provide the best application experience.
Overfill the Repair Slightly
Overfill the repair slightly when applying so you can sand it down to a smooth, flat finish when dry.
Dip Putty Knife into Water
For a smoother finish, dip putty knife into water and lightly smooth filler prior to drying.
Achieve a Smooth Finished Repair
Dual-grit sanding using medium (60 to 100-grit) and finishing with fine (120 to 220-grit) sandpaper will help achieve a smooth finished repair.

Yes, mold, mildew and algae growth is common on the exterior of homes that get a lot of shade or are battling humid and hot conditions. It often shows up on the east facing side of a home but can appear in other areas based on the amount of exposure to shade, heat or humidity. Algae is unsightly and can be time consuming to remove. Having a repair product that is mold, mildew and algae resistant means it won’t grow on or around the repair so the filler stays looking clean and new.
DAP® Platinum Patch should not be used for floors or as a caulk, sealant or joint filler over cracks & joints where expansion & contraction may occur or as a skim coat. It also should not be used when staining is preferred or for continuous underwater use.
