Sealing Coloured Concrete with Oxide in the Mix – 7 days after the pour
Same day sealing not recommended. Due to the possibility of unknown additives that can be present in oxides or colour concrete premixes, we take the following approach to sealing new coloured concrete.
DAY 7 – (minimum 7 days after pour)
Lightly broom and rinse the surface of the new concrete with water thoroughly. Do not use high-pressure systems this early in the curing process on a fresh slab. Whilst the concrete surface is wet, apply Pro Seal 770 (mixed with 4 parts water:1 part concentrate) at a rate of 1 Litre per 5m2. Wait for 15 minutes and see if there is any puddling. Be sure to broom out the first coat evenly, pulling puddles to dry areas. Let dry for 24 hours before applying the second coat of Pro Seal 896.
Rinse the surface of the concrete down clean and apply the Pro Seal 896 (mixed with 4 parts water:1 part concentrate) at a rate of 1 Litre per 5m2. Wait for 15 minutes and see if there is any puddling and then broom the surface evenly.
