What is the working time for Thinset? Is Thinset waterproof? As Jason described, thinset itself isn't waterproof. It isn't degraded by water, and does resist the flow of water somewhat , but definately does not "waterproof" any tile installation the way a membrane will.
How do you know when thinset is dry? You may notice that the edges of the thinset or the thinset showing through the grout lines looks dry. Don't be fooled by this. The thinset under the tiles isn't receiving as much air as the edges and is therefor not fully cured. What happens if you put too much water in Thinset? If you put too much water in thinset several things happen. This can easily make the tile go too low, sending thinset up the grout lines causing an unnecessary mess, and then you have to peel the tile back up to add more thinset to bring it back up to the level of the other tiles.
It takes a very long time to cure. Which is better thinset or mastic? Mastic is a non-cementitious material that exhibits some pros and cons compared to thinset. Thinset is much stronger structurally than mastic and a waterproof product that will not lose strength when exposed to water. Thinset is the only product that I recommend be used in showers, bathrooms and even floors.
How much water do you add to Thinset? Water Mixing Ratio Thinset is available in powder form in both and lb. The ratio of water to mortar for thinset tile is or 6 qts. Can you use too much thinset? Use just enough thinset mortar to form a solid bond between the back of the tile and the surface beneath. Thinset mortar is not designed to be used to level surfaces before installing ceramic tiles.
It is meant to form a thin layer that follows the contours of the surface. Using thinset to fill gaps results in cracked thinset and poor tile adhesion. Correct an uneven surface with backer board or other patching materials before tiling. If your thinset application is too thick, you will often have difficulty leveling your tiles as you install them. It is also common to see thinset squeeze out from under the tile into the gaps between the tiles.
The result will be an uneven, messy tile job. If you see the signs of too much thinset mortar during installation, immediately remove the tiles you installed. Then, scrape the thinset off the floor or backer board, as well as the tiles themselves. The terms thinset cement, thinset mortar , dryset mortar , and drybond mortar are synonymous. Tile needs a smooth, level surface to be installed on.
You can put new thinset on top of old , but only if the old thinset is perfectly smooth and level. Use a floor grinder and pass it back and forth over the old thinset until it is perfectly smooth and level. Thinset mortar is often the adhesive of choice for installing ceramic, porcelain or stone tiles. Behaving much like cement or mortar, this material creates a tight bond between surfaces that can stand up to the weight of the heavy tiles. The thickness of the thinset is set by the size of the notches used in your trowel.
So for the size tile you quoted, x mm, I believe the recommended trowel size is 12 mm notches. In theory this would bring the floor height up around 6 mm plus the thickness of the tile. Thinset , once mixed, should resemble warm cake icing. Not too thin , but thin enough it's pourable or it falls off the mixing knife.
Only mix enough thinset as you can use in 15 or 20 minutes. The thinset can be sanded using a sandpaper anywhere around 24 to 80 grit. Wrap the paper on a block of wood and the thinset will sand quite easily. Thinset bonds best with a porous surface, such as new drywall or backerboard, which needs no preparation, but you can apply it over painted walls or tiles that are flat and in good condition as long as the shiny finish is removed.
Use the type of thinset mortar specified for your particular tile. If shrink cracks develope overnight don't worry about them, they will fill-in when you set the tile. Go for it. Thinset will adhere to thinset just fine.
To lay tiles with sand - cement traditional way is to apply the mixture of sand - cement in lump on tiles ' back so it has to be done with one tile at a time. Vacuum the surface before pouring the cement. Self levelling cement is liquidy. Very liquidy. Pour your cement.
