Tile renovation putty

1. Product introduction:
This product is a new type of plastering material, an applicable product developed for exterior wall decoration of old buildings. It is the crystallization of high-tech formula and modern scientific processing methods. It has strong adhesion, does not need to be chiselled, does not crack, does not fall off, is waterproof and anti-cracking, reduces processes, shortens construction period, and reduces costs.
2. Scope of application:
1. Paint primer on the base surface of new walls;
2. Paint primer putty for renovation on old finishes (paint, ceramic tiles, mosaics, stone) ;
3. High-end metallic paint bottom putty;
3. Performance characteristics:
1. Strong adhesion to the renovation base material;
2 . Excellent water resistance and air permeability, ensuring the dryness of the wall and paint surface;
3. High crack resistance, effectively preventing micro-cracks in the bottom layer from extending to the surface;
4. Easy to construct;
5. Non-toxic, harmless and environmentally friendly products.
Four. Technical parameters:
Shrinkage (%) ≤ 0.5
Original strength of pressure-shear bonding ≥ 1.5MPa
Water-resistant shearing bonding strength ≥ 1.2MPa
Temperature-resistant pressure-shearing bonding strength ≥ 1.2MPa
Freeze-pressure-resistant shearing bonding strength ≥ 1.0MPa
5. Usage:
1. Mixing ratio: powder: water = 4:1, it also depends on the basic situation.
2. First pour the water into the bucket, then add the powder, and then use a mixer to fully stir it into a paste. After leaving it for 5 minutes, use a batch embedding tool to perform batch embedding. Wait for 4 hours after the first layer of batch embedding is completed. The second layer of putty is embedded and smoothed, and the thickness is controlled between 1.5-2mm. 1.5-2.5 kg/square meter (depending on the flatness of the base surface).
VI. Precautions:
1. Confirm the verticality and flatness of the substrate before use;
2. Avoid mixing the dried paste with water before use;
3. The wall surface should be moistened in advance before construction, subject to the absence of clear water;
4. This product is suitable for construction above 5℃, avoid construction in rainy days;
5. Pay attention to the process of putting putty embedding It should be uniform and flawless. It usually takes 48 hours after the batch is completed to apply various coatings
7. Packaging and storage:
25kg/bag, stored in a cool and dry place, with a shelf life of half a year. </p
