Good afternoon,
I'm nearing completion of my wetroom 900mm X 900mm ,and have bought some glazed ceramic mosiac tiles (20cm by 33.3cm x10mm thick pic attached) for this. Each tile has unglazed grout joints which are not all the way through the tile. I have some questions regarding porosity of these grout joints.
I tested the tiles with water, and noticed that the water seeped almost immediately through these unglazed grout joints, and could see the watermarks on the underside. :yikes: Have I bought the wrong tiles??
I was planning to use Mapei ultracolor grout to seal the joints, and then seal the grout joints with a suitable sealer. Will this suffice? I'm not too sure now after doing the water test.
I have thoroughly tanked the wet room walls & floor with mapei wps & tilesafe membrane & have installed UFH as well.
I will appreciate any suggestions to the suitability of these mosaics for this area and the correct sealing & grouting procedure.
regards
