TB autoclaved sand aerated concrete block binder

TB binder is a thin-layer bonding material designed for autoclaved sand aerated concrete blocks. The product has excellent water retention, is easy to operate, has good adhesion to the base material, and is suitable for lightweight materials. The thin-layer construction provides uniform bonding strength to the upper and lower blocks, ensuring the smallest joints between the blocks, and enabling the joint of lightweight materials to have excellent integrity and aesthetics.
2. Product features

2. Good water retention
3. Good crack resistance
4. Good weather resistance
>5. Easy to operate

3. Scope of application
This product is mainly used for lightweight walls such as autoclaved sand aerated blocks, lightweight blocks, lightweight boards, and ceramsite blocks. Bonding of bulk materials.
IV. Base layer requirements
The surface of the building blocks must be solid, flat, without cracks, release agents and media that may lead to isolation. Blocks with defects such as falling corners should be repaired first. If they are The surface of the block is prone to dust, so the surface should be treated with primer first.

5. Instructions for use
1. Stir with an open mortar machine or a hand mixer. Add clean water to a clean container, add the binder while stirring, and stir until a uniform consistency is achieved. Thick, no lumps and no bubbles, let it sit for 5 minutes, stir again and use. No need to add water when stirring again.
2. Use a spatula to apply the mixed slurry to the surface of the lightweight bricks, with a thickness of about 3-4mm, then lay the blocks in the corresponding positions and press them firmly.

VI. Precautions
1. The construction temperature should be above 5℃, strong sunlight and rain should be avoided during the construction process, and vibration should be avoided within 48 hours after construction.
2. The mixed slurry should be used up within 2 hours. The slurry that exceeds this time should be discarded.
7. Storage and Packaging
This product is packed in lined film bags, 25kg or 50kg/bag, stored in a ventilated and dry place, moisture-proof and sun-proof, with a shelf life of three months.
