Adhesive Notched Trowel Complete with A2 Blade amtico & karndean

Product Information

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. 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. 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. The fibre reinforced format reduces lateral movement during installation and offers improved indentation and shear resistance. This adhesive has GEV-EMICODE® EC1+ accreditation and is recommended for use with underfloor heating systems. Karndean Universal is applied with A2 notched trowel and needs 10 minutes or less for airing, and allows for 20 minutes working time. A U-shaped ridge, on the other hand, spreads OUT when embedding a tile into the bed. 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. Which trowel size to use? 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.

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. 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 A2 adhesive spreaders are used as a Karndean trowel or an Amtico trowel, also suitable for use on all other LVT’S When you fully embed the tile into the bed of adhesive, it spreads out the adhesive ridges evenly into the spaces between the trowel lines. Since the spaces between the ridges have the same size as the ridges themselves, this will split the height of the ridges in half. So a 12mm x 12mm trowel will leave a 6mm high bed of adhesive beneath the tile. A 6mm x 6mm trowel will leave a 3mm bed of adhesive beneath the tile. 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.).

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 Karndean PSA: suitable for normal environments protected from direct sunlight, Karndean PSA is a solvent-free high grab Pressure Sensitive Adhesive with superior bonding strength. This type of adhesive is applied with A2 notched trowel and needs 20 minutes for airing, and allows for 120 minutes working time.

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