Grout Stop grout going black in new bathroom. - Tile Advice

Bathfix Bob · Sep 16, 2018

Just doing a bathroom with white ceramic wall tiles and grey porcelain floor tiles. I've been asked to prevent the grout going black and dirty over time and to ease cleaning. Can I use something like Stain Stop on the grout?

Its Mapei on walls and Bal on floor.

Grout sealant will help. Try to avoid white grout. Epoxy only sure fire way

Also tell them keep their bathroom warm in the winter and use their extractor fan so that water doesn't condensate on the tiles surface . This will help with black mould which is caused by condensation .

Thanks guys, which is the best grout sealer?

In my experience it is the LTP aerosol

Really? So you wouldn't use Lithofin stain stop, is that just for tiles?

No, it seals grout too and is an excellent product. I just find the aerosols easier to work with on just the grout

Got a feeling they are not to concerned about drying times as well unless that is just the universeal one

We've got some aerosol already on site but its been warned from CTD that you need to be careful around the bath and other plastics as it may mark them. I don't want to spray stuff around that's going to ruin everything it lands on.

Used this product quite a few times in bathrooms at rental properties and it works

I’ve used LTP grout sealer and I spray it into the lid and apply it with a paint brush so I know I got 100% coverage and it’s less messy

Does it stain or mark the tiles? I can't bring myself to use what smells like clear laquer all over the tiles.

These sprays are invisible once sprayed and dried, plus it works!

The biggest cause of mould will be lack of ventilation, as already mentioned.

You need a mixed flow or centrifugal extractor fan. They’re not expensive (about £60 to £100) and will clear the room far better than the in line all in one kits.
