It is important to treat woodworms as soon as you find out that your furniture has been infected.
To kill woodworms on varnished wood, place it in an open area that is well ventilated.
Step 1 – Dry and Clean
First, clean the item well so it is free from dust and debris.
Also, you can remove any stains.
Step 2 – Clean the Varnish or Paint
After cleaning it, let it dry completely before you remove any varnish or paint.
Sanding is the best way to remove varnish or paint.
It is important to get rid of all the paint and varnish so that it can be repainted/vinished again once it’s complete.
Step 3 – Shake and Pour.
Once the item has been completed, find a suitable place to work. It is best to work outdoors with lots of ventilation.
You can shake the can of woodworm killer (Ronseal or Cuprinol) and open it.
Use the recommended amount to brush the entire surface.
To ensure complete coverage, you will need to cover all joints and ends.
Woodworms love to get into corners, crevices and ends grains.
Step 4 – Dry and apply two more coats
The first coat takes approximately two hours to dry.
After it has dried completely, apply another coat to the surface.
Allow it to dry, then apply a third coat.
Step 5 – Paint, varnish, or repair
After the third coat is dry, you can make any repairs if necessary.
You can then prepare the surface for a coat of varnish, or paint if desired.
This is because the woodworm killer has penetrated the surface completely and killed all the worms.
You should fill the holes left by woodworms with wood glue. You can now stain, paint or varnish the surface.
The woodworm insecticide has been trapped inside and is protected from the elements. It will continue to kill woodworms that get past the paint, varnish, or stain.
