Mixture of sand and cement
Sand and Portland cement are commonly used. Portland cement (OPC) is used as plaster mortar, mortar while sand is mined in the river so it is difficult to control sand grain size, cleanliness as well as sand quality.
Very inconvenient to use:
Ordinary Portland Cement (OPG) is usually packed in small bags and sand is bought in large quantities so it is very costly to store. When used, cement and sand must be brought to another location for mixing and due to the mixing of dirt and unhygienic cleaning. Brick should also be soaked in water for at least 1 day before lining with cement mortar mix, and this takes time.
Time consuming and ineffective:
To paste the brick in the traditional way, we plastered plaster into the back of the brick and proceeded to paste the brick, so doing so only made one tablet for each tile.
Aesthetic problems and peeling problems:
If no water is mixed during use, the cement sand mix will dry quickly so it is difficult to adjust the tiles after the tiles. This can easily lead to poorly laid tiles that cause aesthetics and cement sand mortar with poor adhesion, so it is easy to peel off after a period of use. Brick tiles in the traditional way by plastering the plaque on the back of the brick easy to create holes under the brick to water easily penetrate deep below. This will cause staining of the stain. In addition, the brick will break in the area without any binder underneath
Restrictions on use:
Sandy cement has low adhesion due to sand mixed with impurities and mixing doses are not guaranteed. In addition, cement mortar has many limitations when used for tile in some cases such as:
- The type of brick less water absorption
- Granite brick 60x60 cm or larger size brick
- Glass mosaic - on the surface smooth
- Tiling on the old brick surface
- On the surface is easy to move
- On high pressure areas
Causing waste of materials:
By traditional bricklaying by plastering the tiles on the back of the brick to adjust the flatness of the floor and ensure adhesion requires a thick layer of mortar. This will make the load structure heavier. Moreover, wastage of raw materials when the mixture dry faster before using to paste.
Tile Adhesive is a ready mix and includes carefully calculated ingredients such as OPG Portland Cement, carefully selected fine sand and additives to improve the characteristics of tile adhesive. . High-grade brick adhesive can also be used to place bricks on the surface of old bricks, on smooth cement surfaces, on wood surfaces (with lining) or on other special surfaces.
Easy to use
Tile adhesive is easy to use, just mix it with clean water and use. The product is packed to facilitate transportation, less dust and therefore the construction area is cleaner. Brick does not need to be soaked first, just remove the brickwork and conduct slices with tile adhesive
Adhesive lining is commonly used to coat tile adhesive on the surface of 1m² and provides high adhesive performance. Then continue to paste the tiles on the glue and quickly adjust the tiles to align.
Brick tiles allow bricklayers to easily adjust bricks for a specified period of time. This improves brilliance and brings aesthetics to the area. Using serrated jaws to glue the tiles to cover the back of the brick and thus reduce the incidence of broken bricks in angled way, the water penetrates beneath the brick and causes the condition. brick and flowering (salt, calcified, tarnished). In addition, the adhesive is coated on the surface of paving and back of brick to provide good adhesion and high durability.
Tile Adhesive is manufactured specifically for special applications such as glass tile mosaic tiles, large size granite tiles (from 60x60 cm or more), paste tiles on smooth surface, on dry walls, on on the surface of old brick, exterior wall area, parking area, industrial areas - workshops, swimming pool area and other areas.
Using sawdust to paste tile helps to consume less material. Tile adhesives are much thinner than tiling by cement sand, and this makes the structure lighter. A 20kg tile adhesive can be used to tile the area of about 4-5 m². A 25kg tile adhesive can be used to tile the area of about 6-7 m².
Note that the coating thickness depends on the flatness of the substrate, construction tools and techniques of construction workers.
BENEFITS AND LIMITATIONS OF TILE ADHESIVE AND MIXTURE OF CEMENT
Fast and effective
