You’ll need to remove any existing colours, stain or varnish before applying anything new. Put on your safety gear, and then load a 60 grit sanding disc onto your power sander. This will cut into the top layer efficiently, removing the surface swiftly. Once you’ve completed one layer of the coarse grit, you can slowly transition up to a 120-grit sanding disc to finish it off and create a smooth finish. Sand any corners or tight spaces by hand.
Wipe down your wardrobe to remove excess dust before moving onto the next step.
Safety tip: Always wear the appropriate safety equipment (safety glasses, ear muffs and a mask, for example) and always follow the instructions for the product or equipment.
