Lithofin KF Cement Residue Remover, 1 Litre

This thing will melt cement residue as stated. also did the mold! 😝. Please keep it away from children. otherwise its good for novice Tile DIYers like me.

Worked well for me, pretty pleased. Thought it was a good cleaner and didn’t suffer I any colour issues. It has a very strong smell so I used my respirator and kept the window open but you still get a blast from the odour. However this doesn’t linger after it’s just when you’re using it. Be sure to rinse off any residues and consider a sealer to prevent any water marks depending on the surface. I feel it’s a little over priced for what you get so drops a star for that.

Well, my stupid husband paid £10,000 for a new patio and shortly afterwards he put a large board on one part of it and mixed up a load of cement to do another job. Needless to say he got a lot of cement off the board onto the lovely patio and there was a lot of cement residue on it. I was hopping mad but it's been like it for quite a while now until I looked on Amazon and found this stuff among loads of other products. This seemed to have the best results so I bought it. Well, today, being a lovely day with no rain forecast, he did the work on it and it's fabulous. Not a sign of Cement residue. It was hard work he said, and you need a very stiff brush after it's been applied, but he had a wire one. Would highly recommend and a very good price too.

Its a good product but had to use without mixing as it did not remove the cement stains as sated so a bit expensive as it does not go far . Would not purcahse again.

After trying all sorts of remedies and other chemical products (none of which made the slightedt difference) this did the job with ease. This was a mixture of cement and grout residue with epoxy glue in it too that has built up over a year leaking from underneath an unsealed step. Layers upon layers. You can see it bubbles as soon as it makes contact. In my situation, the combination that worked for me was a slightly stronger solution than they recommended (this went on my porcelain tiles) 50:50 or in the more resistant areas, neat… using a wire brush, wipe with a micro fibre cloth and then a final rinse with water. I was about to call a builder to replace the tiles as nothing had worked but this worked. I needed 2 bottles but it was the best money I’ve spent.

Tried all measures of dilution on cement effect (porcelain tiles) which have grout hazing to no avail. This had no effect at all.

I recently laid a porcelain patio and did the grouting too. This was my first task as such and I’m no landscaper. 80square metres for reference. After grouting and cleaning up, the following day I noticed white marks, which when the patio is wet, doesn’t show. I was depressed ! After all that work thought I did something terribly wrong. After much research found that if your porcelain has tiny perforations or indentations, grout will seep in no matter how much you cleaned off before the grout dried. Wet you patio, get this in a 1 bottle product to 4 bottles water mix. Use a brush or squeegee ( depending on area ) and lather it on rich. Leave for 20/40 minutes depends on stains. If you have grass or plants then you want to mop this up into a bucket before rinsing with a hose. Any stubborn stains and you unfortunately have to scrub at it using same about steps and elbow greese. Leave for 20/40minutes. Hope this helps any that is in a position that I was in !

The builders had left lots of cement haze all over my new porcelain pavers. I tried lemon and vinegar which worked for small parts but I needed a lot. I bought this and you poured it on the cement blotches and it dissolved them straight away. Was so happy it worked
