Polymer cement mortar waterproof latex
The polymer cement mortar waterproof latex is made of imported polymer building emulsion and supplemented with various compound additives. Incorporating into cement mortar can form a unique composite network structure with certain toughness, which greatly improves the crack resistance and impermeability of cement mortar. Due to the different types of polymer emulsion, this product is divided into three types: A, B and C.
product advantages
1. It can double the adhesion of cement mortar;
2. It has excellent impermeability, crack resistance and impact resistance;
3, high temperature resistance, good alkali resistance;
4. The product is non-toxic, harmless, non-polluting and environmentally friendly.
Scope of application
1. Waterproof and anti-leakage works for all parts of buildings such as exterior walls, roofs, toilets, and pools;
2. Waterproof and leakage prevention works for various underground projects such as basements, tunnels, dams and subways;
3, especially suitable for aerated concrete, hollow brick and other porous materials wall anti-leakage surface or brush.
user's guidance
1. Main materials and requirements:
1 cement: general Portland cement with a strength grade not lower than C32.5;
2 sand: according to different construction objects, using medium sand or fine sand;
2. Preparation:
1 When preparing the cement paste, it is only necessary to mix the cement and the latex with a proper amount of water according to the formula ratio, and the amount of the latex is about 0.1 kg/m;
2 When preparing waterproof mortar, first mix the cement and sand according to the proportion of the formula, then add the specified latex and water, and mix it evenly by mechanical or manual. The prepared waterproof mortar is used at room temperature (20 ± 2 ° C), preferably within 1 hour.
3. Construction:
1 Base surface treatment: mortar (or concrete) should be smooth and solid, surface dust, dust, oil and so on should be cleaned. The leaking water should be treated with plugging material first. For parts with different materials of metal and plastic pipe, The surroundings should be polished.
2 waterproof mortar construction:
A. Applying a cement paste on the surface of the treated base layer to improve the adhesion to the base surface;
B. After the cement paste is not sticky, the mixed polymer cement mortar can be evenly scraped on the surface of the base layer and smoothed with a trowel. The thickness is generally 3-5 mm; the basement, Pool: 5-8mm;
C. Polymer cement mortar should be layered: after the first layer of polymer cement mortar is initially set, apply a second layer of polymer cement mortar until the thickness is required (initial condensation for 4 hours, final condensation for 8 hours);
D. Wet maintenance should be carried out after 24 hours of construction. The curing time varies depending on the temperature conditions. It is suitable for 3-5 days at room temperature;
E. When pasting the facing material, apply “cement, pure paste†or “waterproof mortar†evenly on the surface of the base layer and the decorative surface of the decorative material, and then attach it to the base surface and find it compact.
Storage and transportation
1, should be sealed and stored in a cool place, the shelf life of 12 months.
2. The three types of product packaging are: 4kg/barrel, 20kg/barrel, 50kg/barrel (can be used with 50kg/bag of cement)
