Easyflow in Shrewsbury ask are you unsure which products to use on your Anhydrite screed floor

Here at Easyflow we have put together a list of recommended compatible products that you may want to consider using to ensure compatibility between products at all stages of the flooring process.

If you are using a final floor finish which will be fixed to the screed’s surface using an adhesive then you will need to lightly sand the laitance off the surface of the screed before using a compatible primer and adhesive. We recommend sanding your screed floor between 7 to 10 days after installation.
