Construction Method

Dry enough.
Remove foreign substances such as rust, remains, dust, sand, grease, paint, and etc. by adversely affecting the adhesion of urethane Waterproofing material to the grounding impregnation.
Since there is high risk of leakage around the penetration pipes and drains, remove 3-5 cm groove for sealing.
The drain should be protected with plastic to prevent clogging.
Seal the cracks in the slab and attach the insulation tape.

After arranging the grounding impregnation, apply primer with rollers, brushes, and sprays.
Make sure to not over-apply the primer.
Sufficiently dry and harden to avoid detachment.

Combine the subject matter and hardener with the specified mixture ratio.
Use a plastic container with a round bottom and a container with a capacity of appropriately 1.2 times the total amount to mix.
If necessary, add 3-10 percept of the specified solvents according to season and weather. Then, mix sufficiently.
Use a motor stirrer for 5 or more minutes to stir the combined subject and hardener.

Apply urethane from the vertical within the pot time with trowel, brush, or roller.
Second application shall start immediately after the texture dries up (There is a risk of interlayer detachment if the surface becomes contaminated or completely hardened.)
Apply evenly so that bubbles are not created.
