General waterproof coating related introduction
Universal waterproof coating, also known as GS waterproof coating. It is a two-component waterproof material composed of a liquid material composed of an acrylic emulsion and an auxiliary agent and a powder composed of cement, sand and mineral powder in a specific ratio. After the two materials are mixed, a chemical reaction occurs, which not only forms a surface coating waterproof, but also penetrates into the inside of the substrate to form a crystal repressing water, thereby achieving a double waterproof effect. The company that produces such waterproof coatings on the market is Leibangshi.
Features

â—ŽScope of application:
·Indoor and outdoor cement concrete structure, mortar wall structure wall, ground;
· Waterproofing of the bathroom and bathroom, kitchen, floor, balcony, pool floor and wall;
·Used for smearing treatment before laying stone, tile, wooden floor, wallpaper and plasterboard to prevent moisture and salt pollution.
â—Ž base surface (substrate) treatment:
·The substrate must be firm, flat, clean, free of dust, greasy, wax, mold release agents, and other debris;
·There are pores, cracks and unequal defects on the base surface. It must be repaired and smoothed with cement mortar in advance. The expansion joint is recommended to be affixed with plastic strips. The joints must be coated with a layer of non-woven fabric. The nozzle filling is recommended to use Leibangshi nozzle grouting. filling;
· The yin and yang corners should be smeared in a circular arc shape (or V shape); ensure that the base surface is fully wet, but there is no clear water;
• Newly poured concrete surfaces (including plastering surfaces) should be allowed to dry completely before application.
â—Ž How to use:
· Stirring: first pour the liquid into the container, then slowly add the powder, and stir for 3-5 minutes until a uniform slurry without powder and particles is formed; (preferably using a stirrer)
· Brushing: brush directly on the base surface with a brush or roller brush, the force is evenly used, can not be missed brush; generally need to brush 2 times (depending on the use requirements), each brush thickness does not exceed 1mm; before Once it is slightly dry, apply it again (just not sticky, usually 1-2 hours apart), vertical cross-over brushing, the total thickness of the brush is generally 1-2mm; if the coating has been cured, brushing The other layer is first moistened with water.
· Maintenance: After 24 hours of construction, it is recommended to cover the coating with a damp cloth cover or spray water.
·Protection: Before the construction is completely dry, please take measures such as prohibiting stepping, rain, exposure, and sharp damage.
·Inspection (closed water test): Please make sure that the waterproof construction is qualified after the waterproof layer is dry (at least 24 hours in summer and at least 48 hours in winter) for 48 hours. Lightweight walls must be tested for water spray.
â—Ž Note:
· Please follow the above basic treatment and use method;
· Suitable for use in the environment of 5 ° C - 40 ° C, to avoid high temperature, low temperature and outdoor rainy weather;
· Single layer coating should not be too thick, especially at the nozzle and corner to prevent cracks;
· Please keep a ventilated environment after construction to facilitate the drying of the waterproof layer;
· Please avoid damage to the waterproof layer during the later construction;
· It is forbidden to use pure cement paste when laying tiles on waterproof layer, and please apply according to the requirements of tile use and leave gaps. It is recommended to use Leibangshi tile glue or Leibangshi mortar glue;
â—Ž Reference dosage: 1.5-2.0 kg square meters under normal circumstances; the actual dosage is determined by the use, the location of use, the roughness of the base surface, and environmental factors. For details, please go to the place of purchase.
â—Ž Product transportation: According to non-dangerous goods requirements. Prevent rain, exposure, freezing, collision, inversion, damage to packaging, etc.
â—ŽStorage method: Store in a cool dry place;
â—Ž Shelf life: The shelf life of the original package is 12 months under normal storage conditions.
Synthetic polymer waterproof coating
Ast synthetic polymer waterproof coating film, with a variety of polymer polymeric materials as the main film-forming material, adding thixotropic agents, anti-sagging agents, anti-precipitation agents, thickeners, leveling agents, anti-aging agents and other additives and catalysts, The synthetic polymer aqueous emulsion waterproof coating film processed by the special process has excellent high elasticity and excellent waterproof performance. The product is non-toxic, tasteless, safe and environmentally friendly. The coating film has high water resistance, alkali resistance and UV resistance, and has high elongation at break, tensile strength and automatic repair function.
Features
(1) Green environmental protection
Compared with other solvent-based waterproof coatings and waterproofing membranes, “Osta†waterproof materials are environmentally safe. The product is non-toxic and tasteless and has no adverse effects on the environment and the health of personnel.
(2) Excellent aging resistance
The product has stable performance under the action of ultraviolet light, light, heat and oxygen, and the service life of the material is more than 20 years.
(3) Strong adhesion
The products have excellent repairing and bonding properties for common building materials such as concrete base, glass, ceramics, plastics, metal, asbestos tile, floor tile and original waterproof material base, and the bonding strength is extremely strong. It does not peel off or delaminate under the action of external force, and can form a stable waterproof whole.
(4) good permeability
Due to the good permeability of the material, the material can be infiltrated into the pores of the cement-based material when the material is applied, and the water seepage channel is blocked, and the waterproof effect is reliable.
(5) Good elongation
The elongation at break of the product is ≥600%, and its crack resistance is excellent. It has a high shielding effect on the cracks in the base layer. Even if the base layer produces micro cracks due to external factors, fracture and leakage will not occur.
(6) Good resistance to high and low temperature
The product can withstand high temperature up to 170 °C without flowing, and low temperature -20 °C without brittle fracture.
(7) The product has vivid colors
The product can be blended according to the design requirements and user needs, with excellent thermal insulation and decorative beautification. Therefore, the product belongs to decorative and multifunctional waterproof materials.
(8) Convenient construction
The product can form a continuous waterproof layer by brushing and scraping on any regular or irregular base surface. It can be applied on the wet base surface, the product can not be foamed, the film forming effect is good, the curing is fast, and the construction period can be effectively shortened.
(9) Wide range of applications
Products can be widely used in building roofs, basements, underground garages, indoor kitchen and bathroom, water room, balcony, facade façade, slats, window sills, window sills, column sills, pipe trenches, grain depots, water towers, swimming pools, The tunnel, steel structure factory floor, power plant cooling tower inner wall waterproofing, etc., are suitable for construction in construction climate zones across the country.
Construction process
1. The base level requires flatness, no sanding, no bumps, no cracks.

4. When painting, it should be applied horizontally and then vertically.
5, special parts can be used for reinforcement treatment with non-woven fabric or fiberglass cloth.
6, the general waterproof project using the product coated twice to achieve waterproof effect.
Construction requirements
1. Base treatment: The waterproof base layer is required to be firm, flat, clean, free of clear water, crack-free, and uneven. The cracks must be treated with cement mortar or Osset repair mortar.
2, the product for different waterproof projects, different construction requirements, the use of 2-4 times construction, if necessary, add tire base cloth treatment.
3. If the product has a precipitate that is evenly stirred, it can be directly applied.
4. The water storage test is generally carried out after the coating film is applied and dried.
Reference dosage
1.2mm thick usage 2kg/m2.
Coating film thickness: The film thickness per square meter of material per square meter is about 0.6 mm (excluding the thickness of the reinforced cloth).
Precautions
It should be applied at temperatures above 0 °C.
