Seal garage floor and new driveway - which should be done first?
Michael

I have a new asphalt driveway that I want to seal. I also want to seal/paint the garage floor. Which should I do first? The garage floor was painted many years ago and most of the paint is worn off. I suspect that I’ll have to use muriatic acid or something similar to remove the remaining paint, clean and etch the floor. Will the muriatic acid harm the unsealed driveway? If the driveway is sealed first, will the muriatic acid damage the sealer? Which should I do first?

I would do the garage first. Try power washing the garage slab first, then use a heavy duty scr aper to remove old paint. Last resort, if you are unsuccessful, use acid wash.

Go to a rental enter and rent a cement grinder. These look like a buffing machine, but where the brushes would be are diamond stones which will totally grind off the old paint while properly abrading the surface of the cement. The only finish I would consider for a garage which actually gets driven on , is a two part epoxy finish. These cure chemically and require floor temps of 65 degrees or higher. A two car garage kit will cost about $100 at a home center.

Regardless of what paint you use, the most important step is properly preparing the cement to get a good bond. The pros who specialize in garage floors use the concrete grinders or peening machines to abraid the surface and clean it.
