July 19, 20187 yr We have just had our external garage retiled. I asked them to use epoxy grout. The tiles have a rough stone like finish and the tiler is having problems removing the excess epoxy from the surface of the tiles. You cannot see any residue but you can feel it as there is a slight stickiness to the surface. They have tried using an epoxy thinner but the stickiness remains. Any suggestions? The grout has The Crocodile brand name and the instructions on the tin give no helpful advice.
July 19, 20187 yr As the tile surface is rough, a steel wool skour ( Ive never written then word and unsure if it is right) might be a good option. If the tile are rough faced, they will accept some agitation. The other option might just be a bit of high pressure water. A photo might help.

July 20, 20187 yr you can also use grout and mortar remover, the hydrochloric acid you dilute with water. Its very effective at removing concrete from tools. you can buy it from thelikes of global home pro, i forget the brand name...like pro clean, or spa clean...one litre will cost about 400bt so its not cheap.

You cannot see any residue but you can feel it as there is a slight stickiness to the surface. What you said is raising a red flag. If you feel stickiness after using epoxy then the epoxy hasn't cured. The red flag is what are the grout lines like? Have they cured? If they have, why have they? 3 possible causes the epoxy was not mixed it was not mixed with the correct proportions the correct amounts of resin and harder were used but they didn't stir it for at least 1 minute. cleaning it, vinegar, acitone, AAA thinner, alcohol, abrasives
July 22, 20187 yr Author Thank you for the replies. We used HG grout remover which worked even though it’s designed to work with cement based grouts.
