SPU301 ductile elastic one-component polyurethane waterproof coating
SPU301 ductile elastic one-component polyurethane waterproof coating is a kind of moisture reactive waterproof coating, which reacts with moisture in air to form flexible, continuous and seamless rubber waterproof film. Suitable for kitchen, toilet, floor, balcony, non-exposed roof, basement, swimming pool, square roof and so on.
Usage method HOWTO USE
1. Basic treatment: the base should be smooth, solid, dry, no sand, cracks, uneven and other defects, no dust, oil stains and other dirt;
2. Detail treatment: the yin and yang angle, pipe root and other nodes are first painted with 1 times twice as the additional waterproof layer, and the yin and yang angle is made into circular arc;
3. Large surface construction: waterproof coating should be coated 3 times and 4 times, and the total thickness of coating film should be 1.5 mm ~ 2.0mm. The first time should be thin coating, to seal the pores of the base, after each coating should be fully solidified and then carried out the next construction, to the interval of 24 hours is appropriate, and the last time is perpendicular to the direction of the previous coating. After the coating waterproof layer is completely dry, the protective isolation layer should be set up according to the relevant specifications.
4. Finishing layer construction: facade part, in order to increase the adhesion between the facing layer and the coating film, the general method is to sprinkle the clean medium sand on the surface of the coating film sparsely before brushing it for the first time. After the waterproof layer is completely dry for 48 hours, the finishing layer is constructed according to the design requirements.
Matters needing attention MATTERS NEEDING ATTENTION
The construction site should be well ventilated. The construction personnel should do a good job of protection: the paint should be opened immediately and used up within 4 hours after opening the cover; it is strictly prohibited to construct in the environment of high temperature, rainy and snowy days and above grade 5 gale:. Direct use does not require the addition of any diluent, special circumstances need to add diluent, please do tests to confirm that the diluent used will not affect the drying rate and film quality before use; non-exposed products, can not be directly used for exposure
In outdoor waterproofing construction, it is necessary to do protective layer when used for outdoor waterproofing; when a small amount of precipitation occurs, please stir evenly with electric agitator and use it evenly, which has no effect on performance and use.
1.7kg/ m' is needed to brush 1 mm thick film with reference dosage KEY POINTS OF CONSTRUCTION.
