Dado Finish Sealer

[John93]

I’ve just had the external seating area completed with dado rendering and would like to seal it so the concrete finish remains as it is.

Question 1: How long should I allow it to cure before sealing? I’ve read online that 28 days is recommended.

Question 2: I’ve purchased the Crommelin Satin Wet Look Concrete & Paving Sealer, which recommends mixing the first coat with 10% Crommelin Cleaning & Thinning Solvent. How do I accurately measure the 10% ratio?

Thank You !
