The skirting is sanded and filled for a smooth and finished look and then appropriately cleaned to remove any dust or debris, either with a damp cloth or a firm brush.

Starting Caulking

The areas which need caulking are to be marked first and then start from one side of the wall. Different brands produce caulk; it comes in a long cylinder with a nozzle at the start, which is to be cut with a sharp cutter, making a straight cut for the perfect flow of the caulk.

Avoid cutting too far off the nozzle tip; in that case, you will have a thick caulk supply that can be messy and spoil the work area. Having a small bead of caulk is more desirable for a clean and professional outcome.

Caulking Techniques

To start the caulking, you must first put your decorative caulk inside the sealant gun and press the piston. If you are using it for the first time, it’s better to take some tries on an experimental basis before starting on the actual site.

Also, keep tissue paper and a basket with you to immediately wipe out any excess caulk from the nozzle to avoid any mess.

Now with a steady hand, start pushing out the caulk with the gun from one side of the skirting and take it along to the end of the wall.
