New Grout Crumbling


Postby Did it myself » Thu Jan 08, 2009 12:32 pm

Can anyone advise please.
My bathroom was tiled a few weeks back by a professional tiler. The bath surround was boxed and then tiled.

Some small areas of grout are crumbling away on the bath side and I'm wanting to repair these areas. The tiler left me some grout (powder) and am hoping someone can tell me what ratio I should mix with water?

Also, is this type of crumbling to be expected with it being new grout? or is this crumbling happening because of the movement of the bath? Is this likely to be a consistent problem in the future or will it settle?

Thanks

Mix with water until it look similar to double cream. Run your finger through the mixture and it should leave a groove. Some should stick to your finger without falling off. For a small area, mixture is not critical.

If the tiled area is flexing this problem will keep re-occurring. If the area is allowed to dry for a week or two without being disturbed, it may crack but not fall out.
