After I have cleaned wood with Roof & Deck Concentrate should I apply a protectant?
Yes! Yes! Wood naturally “grays” over time due to weathering and exposure to U.V. rays. Unprotected wood, even though clean will still “gray out” rapidly without a protectant. Top • When cleaning cement how much pressure should I use? Cement, due to its porous nature, is very difficult to clean. The higher the psi, the better. Note that our products will brighten and remove oils, grease and mold and mildew stains but will not remove rust stains. For rust removal, we recommend our rust and stain remover called Premier Surface Prep Rust and Stain Remover to remove the toughest rust stains easily. Top • When using Roof & Deck Concentrate to clean vinyl siding, aluminum siding or painted surfaces at thirty to one should I allow it to dry? No. On these surfaces only, you should not allow Roof & Deck to dry. A dwell time of five minutes is sufficient. Also, at this dilution it may be run through the downstream injector for application. A small test spot should be performed prior to cleaning
