Filling Cracks Between Wall And Ceiling

Do not let the patch become raised over the crack.

Filling cracks between wall and ceiling. Homeowners can fill these commonly occurring hairline cracks with new plaster and repaint the ceiling. Cracks that appear where a ceiling intersects a wall may be due to truss uplift roof trusses tend to move a little when there is a seasonal change of temperature or humidity. Cracks that cause concern are those which run across the length of a ceiling and then continue down a wall along the same line.

Step 5 cover the tape with more joint compound. So the crack between wall and ceiling is hidden by the sliding cove molding. Start by cleaning loose material out of the crack and fill it with joint compound.

Depending on the depth of the crack you may need more than one coat. Countersink holes first then screw coving up then use decorators caulk to fill gap between coving and walls ceiling. It works best on hairline cracks but it s worth a try on wider cracks too.

This is common and most homes are engineered to handle movement due to truss uplift. It forms an elastic film that stretches and contracts along with the crack. This is the one fix that is comparatively easy to retrofit but do not paint the walls in the summer to avoid having an unpainted stripe around the room when the molding rises during the winter.

The coving shouldn t fall off then. It should be flush with the wall ceiling. Then spray on two to three light coats of good bye cracks.

Install decorative cove molding where the walls meet the ceiling and fasten it to the ceiling but not the walls. This is a sign of structural damage usually related to a weak wall. Let each layer completely dry before adding another one to two hours.
