A flawless architectural finish is 70% preparation and 30% application. At Bulwark, we want your projects to stand the test of time, and that starts with mastering the surface.
Internal Walls
- Clean the surface of all loose particles and dust.
- Ensure the wall is completely dry before application.
- Remove any existing old paint or grease.
- Smooth out large irregularities before filling.
External Walls
- Scrape away any algae, moss, or fungal growth.
- Address structural cracks with appropriate base material.
- Wash down surfaces exposed to salt air or heavy dust.
- Avoid application during peak midday heat.

The Bulwark 1:3 Rule
For the perfect consistency, always mix 1 part clean water with 3 parts Bulwark Wall Filler. Use a mechanical stirrer or a clean trowel to mix until you achieve a smooth, lump-free paste.
Pro Tip: Only mix enough material that can be used within 60 minutes to ensure maximum workability.
