Adhesive Notched Trowel Complete with A2 Blade amtico & karndean

Product Information

It is easier to keep a standing ridge on a wall with smaller square-notched than with a larger U-notched.

You must add this amount to the minimum adhesive amount you want beneath the tile to get proper adhesive! Notice the 12mm square notched bed on the left side has the most coverage with the 8mm square notch in a close second.

This adhesive has GEV-EMICODE® EC1+ accreditation and is recommended for use with underfloor heating systems.

A finished placement requires a minimum of 2mm beneath the finished placement, aiming for a 3mm minimum makes it easier to calculate the proper tile trowel size. You can be confident that our adhesives protect indoor air quality and contribute to a healthy environment, both during and after installation. The trowel’s tooth shape and spacing determines how much adhesive is sandwiched between the tile and substrate once the tile is fully installed.When you use a 6mm x 10mm square-notched trowel you will leave 6mm wide by 10mm high ridges of adhesive on the substrate, with 6mm spaces between each ridge.

Measure the amount of space between the faces of the tile on the opposite corner then divide that number in half. They help us to identify popular products and understand your browsing habits so we can display relevant adverts to you. The height of the ridges and the space between each ridge will be the size of the trowel (in this case 10mm).If squeezing the tile in this manner produces a 6mm space between the tiles in the opposite corner, it means the tile is cupped by 3mm. A little extra adhesive beneath a tile is completely acceptable, not enough adhesive beneath the tile is not acceptable. There is more space between the half-moon ridges with a U-notched than there is with a square-notched. Since the spaces between the ridges have the same size as the ridges themselves, this will split the height of the ridges in half.

Using a U-notched trowel and embedding the tile into the adhesive leaves you with a bed of adhesive beneath the tile a little over 1/3 the size of the trowel teeth. There is more to that requirement such as complete coverage beneath all four corners of the tile, but those are the basics. Using a 12mm x 12mm square-notched trowel will leave 12mm ridges of adhesive on the substrate with 12mm spaces between each ridge. Since the adhesive spreads out, rather than folding over first, it is less likely that adhesive will fill the grout line as you embed the tile.Check this by placing the tile as you normally would, then pulling the tile up and checking the back. We offer a range of four adhesives suitable for our different product formats and project situations. While it is easier to obtain complete coverage with a U-notched, you must also use a larger U-notched trowel to achieve the same bed thickness beneath the placed tile. Since a 10mm U-notched trowel and a 6mm square-notched trowel will both leave a 3mm layer of adhesive mortar beneath an installed tile, why choose one over the other? The trowel size determines how much adhesive to put on the substrate, as well as how thick the bed of adhesive should be under the tile.
