Preparing Painted and Plastered Walls for Microcement
In the video below, Richie explains the prep work that you need to complete before applying microcement onto a painted or plastered wall.
If you’re installing microcement onto a plastered or painted wall, then a lot of the work will have been done for you already.
The wall should be completely smooth and free from any movement before you apply microcement.
Make sure the wall is completely dry (maximum moisture content 5%).
If the wall has been painted, then make sure there is no loose or flaking paint left on the surface.
For freshly plastered walls, you’ll need to apply a diluted coat of Primer 100 at a ratio of 50:50 with water, followed by a neat coat of Primer 100.
