DRYWALL OR PLASTER TEST
MEASURING THICKNESS OF DRYWALL

DRYWALL OR PLASTER TEST
Many homeowners and professionals alike aren’t sure whether they have drywall or a plaster wall construction in a project until they drill a hole or pound a nail.

A simple solution to determine your wall type is to look for an edge of your wall, like along the base boards, inside a door jamb or inside a wall vent. If using a wall vent, you will need to remove the air vent faceplate, which is usually held by a screw. Observe the edge of the vent hole. If cut fairly clean, you should be able to observe the material type.

Drywall is characterized by face paper in front and in back of a center of gypsum (chalky) material. The face or backing paper can be torn. Plaster, a crumbly powder-like substance, will usually be a layer in front of a carrier material such as 1/8'' or 1/4'' wood slats or a wire mesh.

MEASURING THICKNESS OF DRYWALL
An easy way to determine the thickness of the drywall you have is to seek out an air vent in your wall. Remove the air vent faceplate, which is usually held by a screw. Observe the drywall edge of the vent hole. If cut fairly clean, you should be able to measure the thickness with a ruler.
