Urethane Top Coating (PUC)

Use
  • Role of protecting urethane waterproof layer from external contamination
Packaging Unit
  • Motif(A) : 4kg / CAN
  • Hardener(B) : 12kg / CAN
Mix Proportion
  • Motif(A) : Hardener(B) = 1 : 3 = Weight Ratio
Construction Method
    1. Arranging Grounding Impregnation
  • 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.
    2. Apply Primer
  • 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.
    3. Mixing Urethane
  • 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.
    4. Apply urethane
  • 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.
