It's not unusual to see stress cracks on the plaster walls in older homes. Stress cracks happen when a structure moves or settles. These crevices can appear anywhere on a wall. They just don't happen on the seams of the drywall. They are commonly seen starting from the corners of doorways or windows. Stress cracks can easily be repaired no matter how long they are. All you need is stress tape.
Pull the end of the stress tape out from the roll. Hold the end onto the start of the crack. Pull the roll out and over the length of the crack to determine how much stress tape you need.
Cut the length of tape you need with a pair of sharp scissors to repair a plaster wall.
Peel the protective backing off the tape. Position the end as close as you can get to the beginning of the stress crack. If you can place the end underneath the trim on a doorway or window, do so.
Press down on the end of the stress tape and hold it in place. Hold the rest of the length taut with your other hand. Slowly spread the tape over the crack so it covers it completely. The crack should be in the middle of the tape.
Press the stress tape down onto the plaster wall while you spread it out along the crack. Keep it taut to avoid wrinkling. Press the tape down firmly once you have it in the proper position.
Cover the repaired area with a wall paint that matches the colour of the surrounding wall.
To make the stress tape blend in with a textured plaster wall, spray it with wall texture first. Follow the manufacturer's directions for the best results. After it dries, you can paint the repaired area.
