Application & installation
When to specify
For substrates that are slightly dusty or friable but still sound. Heavily delaminated or soft surfaces must be mechanically prepared instead.
Application
Remove loose material and oil, dilute 1:3 with water, roll on until fully absorbed and allow to dry before levelling. Two coats may be needed on highly absorbent substrates.
