Using TSP (Trisodium Phosphate) on walls is an effective way to clean tough grime and prepare surfaces for painting. The key is to apply the solution properly using the right tools.
Preparation
Before you begin cleaning, ensure the area is ready. If you're cleaning an entire room, it's helpful to decide on a starting point and work your way around systematically to ensure thorough coverage and avoid missing spots. Protect your floors and baseboards with drop cloths.
Applying the TSP Solution
Applying the TSP solution involves using an appropriate tool and technique to clean the wall surface without causing damage or excessive moisture.
Here are the steps for applying the TSP solution to your walls:
- Prepare your application tool: Dip a sponge or soft cloth into the TSP solution. Ensure the sponge or cloth is clean before use.
- Manage excess liquid: Wring out excess liquid to avoid dripping. Too much moisture can damage drywall or lead to streaks. The cloth or sponge should be damp, not soaking wet.
- Apply to the wall: Gently apply the solution to the wall. You can use a circular or back-and-forth motion to work the solution into the surface and lift dirt and grime.
Work in manageable sections, typically from bottom to top to avoid streak marks from drips on uncleaned surfaces.
After applying the solution and cleaning a section, you will typically need to rinse the wall with clean water using a separate damp cloth or sponge and then dry the surface. (Note: The provided reference focuses specifically on the application step).
Remember to always wear gloves and eye protection when working with TSP, as it is a strong alkaline cleaner. It's also advisable to test the solution in an inconspicuous area first to ensure it doesn't damage or discolor the wall surface.
