Application instructions

Start by cleaning the surface thoroughly to remove dirt and any mould release residue and then allow the surface to dry for 1-5 days depending on the time of year.
NB! New concrete must harden for a minimum of 28 days before sealing with WC 1701 is carried out.
Shake the product prior to use! Apply the sealer with a low-pressure spray gun or roll it on using a roller in a primary layer – then apply a second layer wet-on-wet to maximise the depth of penetration. The treated surface must have a minimum temperature of approx. 2°C. After approx. 14 days the anti-graffiti coating can be applied.

Before you begin – Always evaluate the product on each surface to be treated, for suitability and results before overall application. It is important to include previous repairs and repairs in the test area. Different materials / surface compositions can result in absorption and / or appearance differences. Also test the application speed, pattern and technology needed to obtain a smooth surface.
