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 a high-tech formula and modern scientific processing method. The crystal has strong adhesion, no need to chisel, no cracking, no falling off, waterproof and crack-proof, which can reduce the process, shorten the construction period and reduce the cost.
2. Scope of application:
1. Paint primer on new wall base;
2. Old finishes (paint, ceramic tiles, mosaics , stone);
3. High-grade metallic paint bottom putty;
3. Performance characteristics:
1. Strong adhesion , has 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 resistance cracking performance, effectively preventing micro-cracks in the bottom layer from extending to the surface;
4. Easy to construct;
5. Non-toxic, harmless and environmentally friendly product.
IV. Technical parameters:
Shrinkage (%) ≤ 0.5
Original strength of compression shear bonding ≥ 1.5MPa
Water resistance Compression shear bonding strength ≥ 1.2MPa
Temperature resistance compression shear bonding strength ≥1.2MPa
Freeze pressure resistance 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 blender to fully stir it into a paste. After leaving it for 5 minutes, use a batch embedding tool to batch the embedding. Wait for 4 hours after the batch embedding is completed before proceeding to the second step. Apply putty and scrape it smooth, keeping the thickness 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 adding water to the dried paste. Mix 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 rainy days Construction;
5. During the process of embedding the putty, attention should be paid to uniformity and flawlessness. It usually takes 48 hours after the embedding is completed before applying various coatings.
7. Packaging and storage:
25kg/bag, stored in a cool and dry place, shelf life is half a year.
