One thing to remember is that even the smoothest appearing concrete is porous.
Normally, most paints will lift off the concrete easily unless it is latex which turns to a liquid with remover application. Regardless, after stripping and removing paint from any concrete, it will have a hazy look to it from the paint film in the pores.
SOLUTION TO THE ABOVE PROBLEM: Following your final washing of the stripper, mix six or more cups of Trisodium Phosphate (Heavy Duty Detergent sold in hardware stores) in a five (5) gallon bucket of hot water. Stir until mixed. Use a stiff brush and proceed to clean with this solution. Rinse with hot water if possible. (If the concrete is extremely porous or rough, you may need to repeat the Trisodium Phosphate method more than once.
** Household soap powders may be used, but
they will not clean quite as well.
STRIPPING BRICK OR ROCK WALLS
This will be much the same as stripping concrete in that brick and concrete are both porous. However, brick and rock are even more so. We, therefore, recommend the following:
Note: The above stripping jobs are where a garden sprayer comes in handy. It leaves you very portable without having to stop for refills as often. However, be sure the equipment contains a chemical-resistant hose and a brass sprayer wand. Clean sprayer thoroughly with water after each use.
