can I lay porcelain floor tiles butted up with no grout. These will be laid on underfloor heating? They are quite large 600 x 600. Any info will help. Thanks
No you shouldn t.. Dirt, dust and every day stuff will accumulate in the joints and be almost impossible to get out. All tiles are designed to have a space, some smaller and some larger than others. The grout the goes between the tiles is part of the system to make it stable. Sealing the grout is a major help in keeping it clean and stain free, if this is your concern. Porcelain is made to have a sanded grout along with a space of 1/8 to about 1/4 inch. Or 3/6 mm This spacing will also help make up for minor tile sizes that will throw you off if you try to but them tight. Any questions you can e mail me through my avatar and check my qualifications there.. GL
