Question:
I have a garage floor that is 7 years old and want to know what is better
stain or paint? I have some stains on the floor from paint and oil which
have been power washed twice already but still are visible. What would stick
better and also cover up?
Answer:
Nothing will stick to oil stains for long, powerwashing is worthless
for oil. Rent a floor scrubber-buffer and get strong soaps, TSP ,
Degreasers etc. and clean until its clean, then etch with Muriatic acid
and check it to specs. Concrete oil stain that Sherwin wiliams carries
doesnt peel if done right . I beleive its called H.C, stain. Paint
can peel eventualy, and usualy does. Cleaning is the most important
step. It will take a day.
No matter what, you are going to need to get it clean first. Power
washer will not do it. Heavy duty cleaners and then an acid wash is needed.
After that I suggest using a quality epoxy garage floor paint. Those of
us who have used it and have followed the prep directions with no shortcuts
have all been very happy with the results. In addition the results will not
let new oil in so you can clean it up.
