Tile Adhesive

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

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.

Construction quality

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.

Many uses

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.

Cost savings

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.

Tile and flooring at the same time


Waste of time
Brick must be soaked
Moisture, water vapor can build up beneath the brick

Do not use drugs for less absorbent bricks such as granite 60x60cm brick or large size brick / stone.
It can not be used to paste bricks on old brick surfaces, or smooth cement surfaces
Can not be used to paste glass mosaics.

1) Select brick by type

- Normal water absorbent brick (water absorption more than 3%) such as ceramic tiles, common wall tiles, brick tiles.

- Less water absorption (water absorption from 0.5% -3%) such as solid brick, granite, granito, glazed tiles, marble tiles, industrial bricks, bricks used in swimming pools.

- Brick almost no water absorption (water absorption less than 0.5%) as marble, artificial stone, glass mosaics, and glass bricks.
Note: An easy way to test the brittleness of a brick is to drop a few drops of water on the back of the brick and observe the water absorption of the brick.

2) Choose bricks suitable for use

Brick tiles for flooring: should choose a few holes, less water absorption to bricks. Bricks will break easily if using wall tiles for the floor. The main purpose of using lining bricks is easy to clean, clean and gives solid foundation. Some other materials have the same features as granite, marble stone.

  • Brick for Wall Tiles: Tiles used for wall cladding are always lightweight. Wall tiles are designed to have good adhesion on the wall and can be used instead of painting or wallpapering. For exterior walls, special ceramic tiles should be used for this area.
  • Brick used in areas frequently exposed to water: Brick rough surfaces should be used to avoid slippery areas in bathrooms, balconies, laundry areas and parking lots.
  • Brick used in areas requiring high aesthetics: ceramic tiles should be chosen to decorate rooms in areas such as the lobby, the living room, and the bedroom.
  • Brick used in areas requiring high durability: High hardness bricks should be selected for use in parking areas, industrial areas, heavy load and circulation areas.

What are Volatile Organic Compounds (VOCs)?

Volatile Organic Compounds (VOCs) are gases emitted by a number of sources in the home. The concentration of most volatile organic compounds is higher in indoor air than in outdoor air.

Where do the VOCs come from?

Formaldehyde is one of the most common VOCs. Formaldehyde is a colorless gas with a strong odor. It is popular in many kinds of building materials such as plywood, sawdust board, and glue. In addition to some types of foam for insulation, formaldehyde can also be found in some types of curtains and fabrics.

Other sources of VOC include the burning of fuels such as gas, wood and kerosene, as well as tobacco products. VOCs can also be obtained from products for personal bridges such as perfume and hairspray, cleaning supplies, laundry detergents, paints, lacquers, varnishes, used for personal hobbies, and from copying and printing machines.

VOCs can be released from the products during use and even when stored unused. However, the amount of VOCs emitted from the product tends to decrease as the product becomes old.

What are the health concerns caused by VOC?

VOCs include a number of different chemicals that can cause itchy eyes, itchy nose and throat, shortness of breath, headache, fatigue, nausea, dizziness, and skin problems. Higher levels of diastolic blood pressure may be lung damage, as well as damage to the liver, kidneys, or central nervous system.

Some VOCs are suspected of causing cancer in humans and have been shown to cause cancer in animals. The health effects caused by VOC depend on the concentration and duration of exposure to the chemical.
