Application Guidelines
Application Method
Surface Preparation
Substrate must be clean, dry, and structurally sound. Remove all dust, loose material, grease, and curing compounds. Concrete moisture <5%. Repair defects with compatible mortar.
Priming
For porous substrates, apply ProTek-Crete diluted 1:1 with water at 0.1-0.15 L/m². Allow to dry 2-4 hours. Non-porous surfaces generally do not require primer
Application
Apply by brush, roller, or airless spray. First and second coats both undiluted. Maintain wet film thickness 180µm per coat to achieve target DFT.
Curing & Protection
Protect from rain for minimum 6 hours at 20°C. Full cure achieved after 7 days. Do not apply below 5°C or above 35°C substrate temperature.
Drying Timeline @ 20°C, 65% RH
