Ressi TA 220
Ressi TA 220 is a dry premix ready to use white cement based general purpose tile adhesive which can be used for standard tile bonding application for internal and external floor and wall tiling. Ressi TA 220 is an ideal tile adhesive for installing mosaic, ceramic, and other general homogenous tiles where a white non yellowing base tile adhesive is required. Ressi TA 220 can easily be applied using the application spectrum as defined by BS EN 5385-1.
- Crack Resistant
- Better bonding
- Salt Free Mix
- Longer open time
- Nontoxic Material
- Excellent workability
SURFACE PREPARATIONAll loose particles and oil shall be cleaned off the surface prior to the application. For hot climatic conditions, the surface may be dampened with potable water. Application on most type of cementitious surfaces like block work, concrete and rough plastered surfaces is possible. The surface should be sufficiently aged (At least 7 days for newly erected masonry surface and freshly plastered surface) before the installation of the tiling may begin. It is also recommended that expansion joints should not be tiled over, and suitable treatment should be done over them. Highly absorbent surfaces should be dampened before spreading Ressi TA 220. Defective and unsound surfaces should be repaired before the installation of the tiles. It is also important to ensure that there is no dust at the backs of the tile, otherwise it may cause hollow sounds and improper adhesion of the tiles to the substrate.
PRODUCT PREPARATIONIt is important that water is premeasured in accordance with the amount of material used. The Mortar powder should be added over the water to avoid the settlement of the material at the bottom of the mixing container. The Mixing container should be uncontaminated, non-corrosive and clean. Only potable water should be used for mixing. It is also recommended that the material should be mechanically mixed with a mortar mixer or other mechanical mixing methods to obtain a consistent lump free mix.
APPLICATIONButtering of the material onto the back of the tiles is usually not recommended as it this may cause poor adhesion. Spread the material evenly onto the surface using a suitable straight edge trowel and then notch immediately. To ensure good bonding, it is recommended not to spread the material more than 1m2 at a time as the mortar may dry up resulting in poor adhesion and causing difficulties in application. After the application and levelling of the mortar, the tiles should be firmly knocked into the position. Adjustment of the tiles should be done at a maximum of 15 minutes after application.
