12/8/2023 0 Comments Sanding cement tilesFull contact of the adhesive on tiles' back and substrate provides strong bonding strength and long lasting tiling work. on the corner, water seeping, and stain or efflorescent. Applying tile adhesive with notched trowel provides full spread on back of tiles and will reduce many problems like broken tiles esp. It makes tiles being laid in line and gives the aesthetic final look. Optimum setting time of tile adhesive allows tiles to be easily adjusted within a certain period of time. Tiles are then continuously laid onto notched adhesive and quickly adjusted into the lines. Notched trowel is normally and efficiently used to apply the mixture of tile adhesive on the area of about 1 m2. Tiles are not needed to be soaked, just un-box them and lay. Bagging product makes it convenient for transportation process, providing low dust and clean working space. It's very easy to use tile adhesive, it will be already ready to use after just mixing with water. High performance tile adhesive can be used to lay tiles on existing tiles, on polished cement, on wooden substrates (with the use of primer), or on other special substrates. Tile adhesive is ready-mixed and specially formulated from OPC, selected fine sand, and additives to improve its essential properties for laying tiles. Moreover, there will be material wastage since the mixture dries faster than the application. There will then be more loads onto structure. Thick layer of sand-cement mixture must be used to lay tile traditionally in lump and/or to adjust the floor level, in order to gain its bonding mechanism. On the areas with high pressure and impact.On substrates where subject to movement.Granito with 60 x 60 cm or greater size.Besides, there are limitations to use the mixture for laying following tiles in the following conditions. Poor bonding strength of sand-cement mixture causes by dirt in the sand and uncertain proportion of the mixture. Moreover, tile will be fragile at the area without any adhesive underneath. Laying tiles traditional way by applying sand-cement mixture in lump at tiles' back will create voids underneath the tiles and water can seep through. This leads to aesthetic problem of the line of tiles and also poor bonding strength, which will be the reason of de-bonded tiles later. Without additive to help retaining water, mixture of sand-cement dries fast and then causes the difficulty to adjust the tiles after being laid. To lay tiles with sand-cement traditional way is to apply the mixture of sand-cement in lump on tiles' back so it has to be done with one tile at a time. Tiles need to be soaked in water for at least one day before being laid with sand-cement, and this is time consuming. OPC and sand must be relocated to another area for mixing and the process is dirty and dusty. OPC comes in form of small bags and sand must be bought in huge quantity, which extensively occupies storage areas. OPC is used for rendering and masonry while sand is normally river sand, which is hard to control grain size, cleanliness, and quality. Sand cement composes of Ordinary Portland Cement (OPC) and sand. Traditional Cement Sand Mortar for Tiling and Its Problems
