LAYING PORCELAIN FLOOR TILES

[Steve Barnes]

I've heard that laying unglazed porcelain floor tiles can be problematic as opposed to ceramic ones. One problem being with the grouting, staining the tile or 'clogging up' the textured surface. Any words of wisdom/tips/warnings/techniques would be appreciated.

First of all do a test on a spare tile and see what happens

You could try using a washboy to remove all the grout quickly to reduce the exposure of the grout to the surface of the tile

I have them on my website.

Some light coloured porcelain can stain even if you are quick with the grout. Usually only pigmented grouts with strong colours .White and grey grouts don't have dye added but beware of black and brown grouts and indeed other strong colours.

Best action is to apply a sealer over the tiles first
