How to use
Surface preparation
The surface should be clean, dry, sound and free from oil, grease and wax contamination. Cement laitance, loose particles, mould release agent or curing membranes must be removed. Fill the surfaces irregularities with suitable product.
Priming
For concrete substrate which will be subjected to negative water pressure, KingProof Primer W should be applied and left to cure before applying KingProof PUT200.
Application
Mix the two components of KingProof PUT200 with a low speed mixer (300 rpm). Keep the mixture cool and away from the sun. Apply the material with a roller in two coats leaving between each coat at least 6 hours and not more than 48 hours.
Cleaning
All tools should be cleaned after finishing with paper towels and then wipe by using KINGKRETE solvent PU. Do not try to clean the rollers.
Limitations and notes
KingProof PUT200 may yellow when left exposed to sunlight.
