If you want minimum 3mm bed of adhesive beneath the tile cupped by 3mm, you must use a trowel that will leave a 6mm bed of adhesive beneath the finished placement. A 12mm square-notched trowel will accomplish the proper coverage in that instance. Visual inspection We offer a range of four adhesives suitable for our different product formats and project situations. U-notched trowels make it easier to keep adhesive out of the grout lines as you embed the tile. There is more space between the half-moon ridges with a U-notched than there is with a square-notched. This makes it easier to have the tile drop into the bed with the edge over an open area between the ridges than over the top of a standing 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.

For the best results, we recommend using Karndean adhesives. Specially formulated to be used in conjunction with our products, Karndean adhesives can be used in live environments without the need for special requirements or ventilation.Proper adhesive coverage meansa minimum of 85% total coverage beneath a tile for a dry area placement (most floors, fireplace, etc.) and 95% minimum total coverage in a wet area (showers, bath surrounds, etc.). A2 adhesive spreaders are used as a Karndean trowel or an Amtico trowel, also suitable for use on all other LVT’S When you calculate the amount of cupping in the tile to determine the properly sized trowel, you still need to visually inspect the coverage to ensure you use the proper size of trowel! Personal preferences U-notched trowel leaves a 3mm bed of adhesive U-notched or square-notched trowel? Which shape of tile trowel to use

Our adhesives are low in Volatile Organic Compounds (VOCs) with most boasting the highest GEV-EMICODE® EC1 accreditation to comply with the strictest environmental and health requirements. You can be confident that our adhesives protect indoor air quality and contribute to a healthy environment, both during and after installation. 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? U-notched trowels normally only have one number. This is both the width and depth of the teeth. I am using a 10mm U-notched trowel, which has a half-moon shaped notch. When you spread adhesive with a U-notched trowel, it will leave half-round ridges on the substrate. Spare handles & blades available.

Above and beyond using the proper method to get proper coverage for a successful placement, your personal preference will help determine which specific tile trowel you use for different types of placement. The square ridges, put down with a square-notched trowel, tend to collapse over on each side when you embed the tile into the bed. Pushing the tile down into the bed of square ridges causes the ridges to fold over from the top of the ridge, then spread out.

There is more to that requirement such as complete coverage beneath all four corners of the tile, but those are the basics.

The size and spacing of the trowel teeth are the basis to measure tile trowel size. This tells you how much adhesive the trowel will leave on the substrate when you spread it out. The trowel’s tooth shape and spacing determines how much adhesive is sandwiched between the tile and substrate once the tile is fully installed. Determining which trowel size is correct for your tile placement depends on both the tile itself and the substrate. More accurately, it depends on how flat the tile and substrate are. The less flat the tile is, the more adhesive you need beneath it, which means a larger trowel size.
