Smoothing Knock-Down Textured Wall

December 20, 2019


This newish home in Kingwood (northeast Houston) had a typical suburban tract home knock-down texture. This would look horrible under the new wallpaper, as well as interfere with complete adhesion.

So I skim-floated the wall by troweling on joint compound (like plaster), and then sanded smooth. After wiping sanding dust off the wall with a damp sponge, I primed with Gardz, a penetrating sealer / primer by Zinsser. Sorry, no “during” photos. 😦

The last photo shows the smoothed surface, primed and ready for wallpaper. (The dark spots are where the original texture was thick and therefore peeking out from under the smoothing compound.)

Knock-Down Texture on a Wall

October 3, 2019


Here is a new sheet of drywall, installed to repair damage from flooding during Hurricane Harvey. The drywall is grey.

The splats of white stuff you see on top is joint compound that has been sprayed on, and then “knocked down” to about a 1/8″ height by a worker with a wide taping knife.

This creates a texture on the wall that is pretty common in newer suburban homes.

The surface should be primed, and then a coat of paint can be applied.

In the case of wallpaper, the wall would have to be “skim floated” and sanded smooth, to get rid of the texture.
