The article elicited the predictable response. Limestone is limestone. Stone is stone. Man, how many different limestones are there??? All have different characteristics and technical properties. Find out exactly what you have got before proceeding. For example, I was given the task by an international architect to select, investigate and then prioritize medium to high quality cream to beige to light-brown limestones. I started with 62 and finished with 3. He settled on a limestone from Portugal that suited the application. I also note from your post that you lay the limestone and then put adhesive on top. Most of the time the adhesive goes under the tiles
Of course you have. At an early stage. As I have said in the article the sealer companies employ an extremely good visual trick into you believing the repellency. That is shortly after it has been sealed. But come back in 6 months and repeat the trick - especially after the floor or stone has been cleaned numerous times with products that are alkaline. Or try the same after the stone tiles have been exposed to UV and general external conditions and try it then. Or watch what happens to the surface of sealed stone after a while after there has been sub-surface moisture. Then of course there is also the issue of which stone. It takes time for problems with sealers to develop. Only last month I had the task of stain testing white marble from China. The marble tiles had been professionally sealed by the company's applicator with a sealer with 10 or 15 years guarantee and regarded as one of the best that there is. What a miserable failure it was.
I know it well. And I know what a source of problems this limestone can be. For a successful job you need to be very careful with this one. I suppose a lot of it has to do with price
Well if u know it so well and I have to be very careful, and u want to validate your point of view, what are your recommendations?
