How about the house guard polyurethane waterproof coating

House guards exaggerate the facts, the effect is generally very poor, it can be said to be a disposable waterproof product, roof waterproofing due to long-term exposure to the outdoor harsh weather environment, so it is necessary to use weather resistance, good performance of the material can also use O7911 polyurethane waterproof coating, its characteristics butcher easy to make temperature curing, short surface drying time, strong adhesion, large elongation, high tensile strength.

The roof is waterproof, and due to long-term exposure to the harsh weather environment outside, it is necessary to use materials with good weather resistance.

Ouqi 911 polyurethane waterproof coating is composed of polyether, isocyanate and other polyurethane prepolymer A component and curing agent B component formed by a series of chemical reactions.

Product features: 1. Easy coating, curing at room temperature, short surface drying time;

2. Strong adhesion, high elongation and high tensile strength;

3. It can be constructed on irregular and complex base surfaces, with excellent integrity and reliable waterproofing;

4. Cold and heat resistant, aging resistant, convenient construction;

5. It has a certain corrosion resistance.

Scope of application: 1 Underground buildings: subway, tunnel, basement, well pit, elevator pit,

pipes, concrete floors, etc.;

2. Roof waterproofing: flat roof, inclined roof, planting surface and sloped roof of concrete, wood, steel and asbestos product structure;

3. Interior and exterior walls, retaining walls, toilets, kitchens, non-edible pools, and swimming.

swimming pools, flower beds, sinkholes, etc.;

4. Expansion joints, construction joints, deformation joints, etc.;

5. It can be used as anti-corrosion floor, anti-corrosion pool and external anti-corrosion of pipelines.

Construction points: 1 base surface treatment: the construction base surface is required to be solid, smooth and dust-free

No oil stains, low concave and damaged areas should be filled and smoothed.

2. Ingredients: According to the ratio of component A: component B = 1:2, first put material A into the container and then add material B, and stir evenly before use.

3 Construction: The construction of the coating is usually carried out in two times, and the mixed paint is evenly scraped on the base surface with a rubber scraper or brown brush.

Consistent thickness ensures penetration and adhesion of the coating to the substrate. After the first coating is dry, the second coating can be scraped, and the scraping direction of the second coating should be perpendicular to the scraping direction of the first coating.

4. If the finished coating film produces bubbles (usually caused by the high moisture content of the base surface), the blistering place should be cut open, the moisture should be discharged, and then repaired with paint after drying.

Polyurethane waterproof coating market ** about 15,000 a ton, pay attention to the implementation of the product when buying, the market pure recall has a lot of polyurethane coatings are not real polyurethane coatings, pay attention to the product implementation standards when buying, the following report data for reference! Implement the standard GB T19250-2013
