Sealing render


New Member
Question for you experienced renderers, I had monocouche applied to my house in the summer the guys did an amazing job but when there is wind driven rain the render looks quite ugly (k rend, polar white)

The main area is a circular bow window that gets hit by the rain and half of the bay gets wet while the other doensnt, my question is if I seal the reachable areas with paraguard or everbuild sealer will this change the appearance of the render and will it look strange if I only seal some areas.

Many thanks for any responses
