Application
Basic waterproof solvent (1st waterproof solvent) for every concrete building
Product configuration
It is made from reaction between special rubber and synthetic resin and has strong penetration, water resistance and adhesion. It is used as basic waterproof solvent (1st waterproof) having excellent adhesion on wet surfaces in case of dust prevention on steel and water resistance on concrete. It is a state-of-the-art highly-enriched liquid waterproof solvent that can be used for different purposes such as reinforcing background, reducing material on waterproof solvents, and increasing life cycle of waterproof solvents if used as primer before carrying out construction on the membrane.
Product characteristics
– As a basic waterproofing agent for all concrete waterproofing (first waterproofing), use it as a primer, mix it with water 1:1 and apply it on the background.
– It is very waterproof even if you use it mixed with cement 1:1.
– It is resistant to temperature changes and vibrations and has excellent adhesion even in moist places.
– It can also be used as a high concentration waterproofing agent.

How to use and caution
| How to use | – Remove the foreign substance from the construction area and fill the crack part and carry out drying before the 1st construction. – For 1st construction, spread the undiluted solution of water bladder using brush, roller, or spray. – For 2nd construction, mix 18l of water bladder and 20kg of cement and use the paint roller for construction. – Carry out drying after 2nd construction and take 3 hours at 20℃. Then, carry out 3rd construction or apply protective mortar. – Water can be added to undiluted solution of water bladder, but it is recommended using water within 1 time in the repair construction or rooftop waterproofing construction. – In case of using water bladder, water can be added depending on the user’s criteria, but it is recommended that additional input is within 10 times. – If you wish to carry out oil urethane or epoxy construction in humid area, use the “water primer” for adhesion on moisture. *** Recommended specification: In rooftops applied with machine plastering (finisher), sanding work should be carried out first. When the concrete strength or background surface is fine, sanding should be applied to background surface. In case of using water bladder, 3 times water should be added. If you wish to carry out intermediate coating with single-liquid urethane, it is recommended of using oil urethane primer and epoxy primer. |
|---|---|
| caution | – Completely remove oil and foreign substances from the construction part. – Freezing might be occurred at 5℃ or under, so refrain from construction. – It should be stored at 5℃ or higher where it is not exposed to wind. |
