questions Marina Gill on 10/02/2019

Hello, I am looking for a non-impregnating sealer for my concrete kitchen floor. It has underfloor heating and has been ground and polished to 1500 grit. I would like a durable glossy finish. What product can you recommend? Many thanks, Marina


The surface tolerance of the 305 HD Clear Sealer will likely not be good enough potentially resulting in a whole host of issues here due to you 'polishing' the floor. 401 Epoxy Floor Primer has the better surface tolerance and does work very well as a gloss sealer. We would recommend a trial area though to ensure you are happy with the finish and adhesion.
