advice on cleaning adhesive from nonslip tiles

[mfj_02]

Hi


I laid some non slip porcelain paving in my garden on a concrete bed with dunlop cf-03 tile adhesive. Unfortunately I got some of the adhesive on the surface of the tiles and let it set. Any advice on how to remove these marks?


I have tried:
Scraping of as much as I can
Using an alkali cleaner to break down the polymer
Using an acid cleaner (grout haze cement remover) to remove the cement
Used a stiff brush on a drill

Open to options as its outside. will a steam cleaner work? or a jet wash?

Try using a stanley knife and carefully pick it away (like try to get the blade under the dried blob of adhesive).... if it's a big dollop, carefully use a sharp chisel and work it off, if you bang the palm of you hand on the end of the chisel the whole dollop can come off in one go.... Just be careful!

Try giving their technical line a ring and see whatthey suggest.
Failing that give Ltp a ring 01823 667242 ask for a sample of solved and Grimex, follow tech data sheet instructions extract when donewith a sponge and cleanwater Do NOt rinseof as this will spread residues and will reseton porcelain.
