If you have noticed a sagging ceiling with a clear cracking along the water-damaged ceiling, then it is the right time for you to organise plaster ceiling repair.

However, if you are still in doubt, better to contact the opinion of experts for your ceiling in Mount Barker so you can get the best solution to your ceiling issue.

Here are some tips to fix a sagging plaster ceiling.

1. Leaking Plumbing Could be the Main Issue – Fix It First

Before repairing a damaged ceiling, you need to first find out what caused the problem. There are several reasons why your ceiling may be sagging, potentially from leaks in your plumbing, roof and/or appliances. Never skip this step or the damage will only get worse in the future and the repairs will only be a temporary and inefficient fix. If you need help determining the root cause you should call the professional ceiling Mount Barker contractors for peace of mind.

2. Inspect the Ceiling and Clean the Debris

Get a step ladder to help you reach the ceiling and push the surface with both of your hands until it touches the lath. Take note of how far the gap between the ceiling and the lathis is. You can do ceiling reattachment if the gap is around 1/4″ to 1/2″.

When pushing the ceiling back, you might be able to hear the sound of the debris above the ceiling. If there is too much debris and the ceiling is badly damaged, you need to opt for a plaster ceiling replacement from the experts of Ceiling Mount Barker instead of reattachment.

3. Drill Holes to Apply Adhesive Injection

Drill holes for adhesive injection right below the lath to make it bond. Make holes with the enclosed 3/16” masonry drill bit, being sure to drill 1” to 2” from the crack. Then drill separate holes 3” to 4” apart along the sagging area. Stop drilling when you feel the drill reaches the lath.

For the adhesive, you can use a water-based latex product for vinyl flooring adhesive or any latex adhesive. Instead of injecting the adhesive directly from the tube, use a caulking gun which will help you fill the hole properly. Inject the adhesive gently to prevent it from coming out of the hole, then wipe off any adhesive residue with a damp cloth.

4. Installing Clamps to Attach the Plaster Ceiling

Next is to attach the plaster to the lath. To attach it perfectly, you are going to need to install clamps. Screw the clamps slowly to each hole within an 8” to 12” distance (you don’t need to install the clamps to all holes).

Wipe off any excess adhesive with a damp cloth, and let the clamps sit for 24 to 48 hours to ensure it is perfectly dry and attached. Use the drill to unscrew the clamps. If they get stuck, use a putty knife to help to remove it.

5. Filling the Holes and Cracks

Fill the holes and cracks with the joint compound until it is full. Flatten with a putty knife, let it dry and then sand it with fine sandpaper. For the finishing, apply a few light coats of paint to camouflage the repair.
