![]() | Question:
My gates get floor hadn't previously been sealed or painted. But it is very dusty when swept. What product shoul I use before paint with epoxy? |
Answer:
Assuming you are enquiring about a garage floor we would recommend Rust-Oleum Epoxyshield Garage Floor Coating Kit as this kit contains everything you would need. | |
![]() | Question: hi can I use this on a flat mirror to etch it with the liquid |
Answer: No, Blackfriar Professional Acid Etch is for use on concrete, it will not etch glass. | |
![]() | Question: Can I put Blackfriar Professional Acid Etch on a concrete floor that has already been painted.. but badly and is not really sticking that much. will it treat it... or should I just start with some Rust-oleum 9100? |
Answer: The Acid Etch will not be able to effectively prepare the concrete if existing floor paint (even if it is badly adhered) is on the floor. The best method of preparation in this instance will be to abrade the floor with a floor grinder or similar to remove the existing paint and provide a key to the concrete surface underneath. Once done the floor should be cleaned to remove any remaining dust from the grinding and then a floor coating of your choice can be applied. | |
