Then, add more mortar to the substrate combing the mortar in straight lines, all going in one direction.The first step is to “key in” a coat of mortar into the substrate for a good mechanical bond with the flat side of the trowel.Furthermore, they assist with air removal to maximize mortar coverage and ensure a strong bond to the tile and substrate. This movement collapses the trowel ridges into the valleys leaving very few if any voids in the mortar which supports the entire back of the tile.Īs the NTCA video explains, trowel ridges running in straight lines are much easier to collapse. Place the tile into the mortar moving it in a back-and-forth motion perpendicular to the trowel ridges. Troweling mortar in one direction in a left-to-right direction, as seen in the National Tile Contractors Association Trowel & Error video (which you'll find at the end of this article) yields the best mortar coverage on the back of the tile. Trowel the mortar correctly by playing it straight! > See Have You Snapped a Chalk Line for Your Tile Layout? 3.

> See How To Select the Right Trowel Notch To Obtain the Required Mortar Coverage 2.

Using a notch that is too small will not allow enough mortar to be applied and likewise will not adequately support the tile.

When a “v” notched trowel is used, the narrow point of the mortar does not provide the coverage necessary to properly support the tile.

Make sure you select the appropriate trowel type and notch size. Select the right trowel type and notch size!

Three Steps to Follow for Correctly Troweling Mortar on Your Tile Installation 1. The best way to avoid these issues, avoid tile breakage, and create a strong tile assembly is to follow the following three steps. When the mortar isn't properly troweled, it creates unsupported space under the tiles which become weak spots that can be easily damaged by the same impact or heavy loads. Porcelain tiles, in particular, can withstand extra heavy service conditions by taking a lot of impact or point load (think of high heel shoes, pianos, refrigerators, or pallet jacks) when installed correctly over a sound substrate. The way you trowel mortar for setting tile makes a big difference. When these three key elements are in place, the tile installation will provide many trouble-free years. Thin-set and the new large and heavy tile (LHT) mortars serve several functions within a tile assembly: What function do thin set and large and heavy tile mortars serve? Let's focus then on how to properly apply the mortar. Not a good situation for the customer and a terrible one for everyone involved in installing tile correctly.

More likely than not, the tile will break - as you see in the image below. You see, when thin-set mortar is incorrectly applied, the installation will many times fail.

It's so critical that readers like you have made this CTEF Blog article the one with the highest readership since we originally published it on June 7, 2016. Hey Rick, do you buy much tile at The Tile ShoP? If so how is the tile there? I've been in there a couple of times but never got any tile.If you're asking how to trowel mortar when installing tile, realize that you are asking a fundamentally critical question. Yes I will roll some Redgard on it to try to save it. I had to take almost all of the thinset off because the idiot that tiled this bathroom installed the tile directly on the plywood (I know Bill does too) and the new subfloor & underlayment does not leave anyroom for anything xtra.I don't even have enough clearance to put down Ditra. Hince I moved just outside the garage door, took my table setup out there and used the grinder w/ diamond blade to get off most of the thinset. Well then I went back to the grinder.garage, my bicycle, my 73 VW and the whole garage was getting dusty and I was getting PO'd about the mess in the garage, on my bicycle and my 73 Beetle. Wet saw too cold and I didn't think it was doing a good job. I thought that was slow so I set up my wet saw. Then I started using the grinder with my diamond blade on it. I used the Multimaster 1st but it was too slow. Thanks to all.now I've learned a lot more ways to get the thinset off.
