Tile Talk: A New Era for Thinset Has Arrived
So what does all this mean to the average installer? It means you better start reading up on things. Around my old shop the saying used to be these setting material guys must think we are chemists. That was when manufacturers were averaging about 10 different types of products each, not the 30 typical of most manufacturers today. Do you really need to be a chemist? No, but you do need to follow the directions about mixing water, temperature ranges, drill speed, and working time. Gone are the days when you can adjust your thinset with water to suit your needs. The 20 or so thinsets we have on hand here range from 4 quarts to 8 quarts for a 50-pound bag, which is chemistry at work. Of course then again, in one instance we have 50 pounds of coverage in a 25-pound bag with 6 3/4 quarts of water and up to a 3/4-inch notch trowel; now that is a lot of chemistry. This chemistry is all about making your job as an installer easier in spite of the outward appearances. Much has been written about "regular" thinsets. Let's take a look at some of the pluses and possible minuses of some of these newer setting materials.
