HOW-TO > PROJECT TIPS > Thompson's® WaterSeal® Oxy Foaming Action Exterior Multi-Surface Cleaner
- Lightly wet surface prior to applying the formula.
- Thoroughly mix 3 caps full (6 oz) of Oxy Foaming Action with one gallon of (preferably) hot tap water. Mix until crystals are dissolved. Use 4 caps full (8 oz) for stubborn stains.
- Use solution within 1 hour of mixing.
- Apply with a watering can, pump-up sprayer, brush, mop, or roller.
- Wait 5-10 minutes and then scrub the surface with a stiff bristle brush to remove all residue that does not immediately come up. Avoid use in direct sunlight and excessive heat to avoid rapid drying. Do not allow surface to dry. Re-apply as needed.
- Thoroughly rinse the surface using a garden hose with maximum nozzle pressure or a pressure washer at 1200 psi with a wide spray pattern. Tougher stains may require a second application.
