Tile adhesive

1. Product introduction:

This product is a high-quality environmentally friendly polymer cement-based composite material. It is a powdery flexible bonding material made of high-quality quartz sand and cement as aggregates, redispersible polymer powder imported from Germany and mixed with a variety of additives. The mortar has a certain degree of flexibility and can be safely released A certain degree of alternating load (internal and external stress) can fundamentally solve the problems of cracking, hollowing, falling off and leakage in building decoration. Add water and stir to use.

It has the characteristics of simple operation, convenient construction, good water retention, high bonding strength, good workability, long adjustment time, and the ceramic tiles will not fall off. It has good water resistance, temperature resistance, waterproof and impermeability, freeze-thaw resistance, cold and heat rapid degeneration resistance, good anti-aging properties and long-term durability.

2. Product application: Choose different models suitable for the adhesion of interior and exterior wall tiles, facing tiles, floor tiles, partition boards, marble, granite, copper tiles, floor tiles, thunder tiles, ceramics and other decorative materials. Knot.

3. Implementation standard: JC/T547-2005

4. Reference dosage: 3-5kg/㎡

5. Construction key points:

1. Base treatment: Clean oil, dust, concrete curing agent, release agent and other loose objects on the surface of the base. When the tensile strength of the base layer is less than the bonding strength of the exterior wall facing bricks, reinforcement must be carried out to ensure it is strong and smooth.

2. Prepare adhesive: water: tile adhesive = 1:4 (weight ratio). Mechanically stir the tile adhesive according to the above ratio for 3-5 minutes (or stir evenly by hand). When the consistency is suitable for construction, let it sit for 5 minutes and stir again to start construction.

3. Paste the tiles: Apply the evenly mixed flexible tile adhesive on the base layer with a toothed trowel. The mortar thickness is 3mm-5mm (the actual thickness depends on the material of the bricks), and then apply The tooth surface of the toothed trowel scrapes out concave and convex grooves, and then the tiles or flake stones are pasted and pressed flat. The tiles can be straightened within 20 minutes.

It can also be pasted using the traditional bonding method. Apply the evenly stirred flexible tile adhesive to the back of the ceramic tile or flake stone, paste it piece by piece, and press it flat. The construction thickness is 3-5mm is suitable, and the tiles can be straightened within 20 minutes.

For bricks with larger thickness and mass, the adhesive thickness is 5-7mm. The setting time is related to factors such as temperature, dryness and humidity. Generally, the initial setting time is 4 hours and the final setting time is 24 hours.

The adjusted adhesive should be used up within 5-6 hours.

24 hours after the ceramic tiles or flake stones are pasted, caulking agent can be used for jointing.

4. Notes: The construction temperature should be above 5℃; outdoor construction is prohibited when it rains; it is prohibited to add sand, cement and other additives without permission.
