A question i get asked all the time is “should you seal porcelain tiles”.
Well, porcelain is becoming a very popular stone for both domestic and commercial clients. It looks great, has a long life and is relatively easy to maintain. Whether it is polished or honed porcelain, its a fantastic and very practical stone to have on a floor.
However, recently i have been called out to view more and more problems on porcelain floors and there seems to be some confusion as to whether to impregnate / seal porcelain tiles or not.
In my opinion you can’t take chances. Sealing/impregnating of porcelain is absolutely vital. Sealing porcelain should be undertaken with a solvent based impregnator, specifically formulated for use on less porous stones such as ceramic & porcelain.
I recommend this to be applied prior to, and after grouting. Why? because I have seen numerous porcelain floors where the grout has bled into this so called “non-porous stone”, causing permanent damage. Look out for my upcoming episode on Stonecare.tv. regarding grout bleeding on polished porcelain (Grout Residue Removers).
So, in answer to the question “Do porcelain tiles need sealing” its a massive YES from me.
The impregnator you chose, should ideally be specifically formulated for low porosity stones and you may need to a apply very thin coats, removing any surface residues as you go (details can be found at www.stonecareuk.co.uk)
