Caberry Polymer Liquid Membrane High Elastic Rubber Waterproofing

I. Product Introduction

II. Core Selling Points

1. Ultra-high elasticity, with elongation at break of 800%-1000%, can cover substrate cracks within 3mm, adapting to substrate deformation caused by building settlement and temperature changes as high elongation rubber coating.
2. Seamless coating, the coating is completely bonded to the substrate, realizing skin-type waterproofing, completely solving the common problems of traditional membranes such as joint water channeling, hollowing and peeling.
3. Strong adhesion, active ingredients can penetrate into the capillary pores of cement substrate to produce chemical reaction, integrating with various substrates such as liquid rubber for concrete, metal, wood, ceramics, etc.
4. Water based liquid rubber formula, non-toxic and odorless, low VOC, complying with drinking water pool waterproofing standards, friendly to human living environment.
5. Excellent weather resistance, low-temperature flexibility can reach -30℃ to -40℃, high temperature resistance up to 160℃, passed 720 hours artificial climate accelerated aging test, service life up to 20 years as UV resistant liquid rubber.
6. High construction efficiency, can be sprayed, rolled or brushed. Mechanized construction can spray about 2000㎡ per person per day, no need for hot melting, cutting and lapping, greatly reducing labor costs as industrial liquid rubber coating.
7. Breathable and water-transmitting, combining breathability and water transmission, solving the hollowing problem caused by non-breathable traditional waterproof materials, can be constructed on wet substrates with moisture content of 40%.
8. Double-sided waterproofing, suitable for both water-facing surface waterproofing and back-water surface waterproofing, adapting to complex waterproofing scenarios such as basements.
9. Anti-aging and UV resistance, no protective layer required for exposed use, can be directly used as liquid rubber roof coating, reducing comprehensive engineering cost.

III. Application Scenarios

• Waterproofing projects for roofs, rooftops, glazed tile roofs, metal roofs, planted roofs of new and old buildings, including liquid rubber for roof, liquid rubber for metal roof.
• Waterproof and moisture-proof projects for grain depots, warehouses, factories, and large-scale infrastructure waterproofing such as bridges, tunnels and civil air defense projects, including liquid rubber for bridge.
• Waterproof and anti-seepage for water body projects such as swimming pools, fish ponds, water storage tanks and sewage treatment tanks, including liquid rubber for swimming pool.
• Anti-seepage and moisture-proof projects for facade exterior walls and new walls, especially suitable for waterproofing of complex special-shaped nodes such as gutters, internal and external corners, pipe roots.
• Indoor waterproofing projects for basements, garages, kitchens and bathrooms, can be used for back-water surface waterproofing treatment, including liquid rubber for basement, liquid rubber for bathroom.
• Waterproofing projects for special places where open fire is not suitable, such as oil depots, chemical plants, textile factories.
• Leakage repair of old building roofs, can be directly constructed on the original waterproof layer without removing the old layer as liquid rubber for renovation.
• Waterproofing for balconies, terraces and other exposed areas, including liquid rubber for balcony.

IV. Technical Parameters

V. Construction Method

1. Substrate Treatment: Clean floating ash, slag, oil, release agent and other stains on the substrate. Level the low-lying parts with 1:3 cement mortar, and remove the convex parts to keep the substrate firm, free of looseness and sanding. Fully wet the substrate with water, and construction can be carried out when there is no standing water on the substrate. It can be constructed on wet substrates with moisture content of 40%, which is an important advantage of flexible liquid rubber coating.
2. Detail Reinforcement: For special nodes such as internal and external corners, joints, dividing joints, pipe roots and water outlets, first use plugging materials for sealing treatment, then use a brush to thickly coat the node parts with slurry. Lay glass fiber cloth or polyester cloth for reinforcement if necessary to avoid water leakage at nodes, especially for crack bridging liquid rubber performance.
3. Coating Application: Stir thoroughly before use. It can be applied by brush, roller or spray. Generally, apply 2-4 coats with an interval of 2-4 hours between each coat. The next coat should be applied after the previous coat is completely dry, and the brushing directions are perpendicular to each other to ensure uniform film forming as single component liquid rubber. When used as a substrate treatment agent, it can be diluted with water at a ratio of 1:2, with a dosage of about 0.2kg/㎡.
4. Curing & Acceptance: Before the coating is fully cured, prohibit trampling, stacking heavy objects and sharp objects. Avoid rain within 24 hours after construction. After 3-5 days of full curing at normal temperature, conduct a water ponding test. The water storage depth should not be less than 20mm, and no obvious drop of water surface within 24 hours means qualified construction. As eco friendly liquid rubber, it is safe for both construction and use.

VI. Packaging & Storage
