Adhesive Notched Trowel Complete with A2 Blade amtico & karndean

Product Information

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.

Karndean Universal: ideal for our gluedown ranges and most subfloors, this is a fibre reinforced adhesive which allows planks and tiles to be laid almost immediately after application. e. a 12mm x 12mm), the bed of adhesive will be half of that measurement, or 6mm, beneath a flat tile over a flat substrate. The u-notch in the center has even coverage, but you need a much larger notch to get the same amount of coverage.They help us to identify popular products and understand your browsing habits so we can display relevant adverts to you. 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. The fibre reinforced format reduces lateral movement during installation and offers improved indentation and shear resistance.

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! 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. Pushing a tile into the bed of rounded ridges causes the ridge of adhesive to spread out, from the bottom, with less possibility of trapping air. 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.I also noticed although the centres stay the same ( 3mm ) the depth varies probably due to different batches. There are two basic ways to determine which size of trowel to use: calculating the warpage (cupping) of the tile and substrate or visual inspection.
