Instead of pulling up that tired vinyl on your bathroom floor, give it a fresh look with a newly repainted surface. Follow these simple instructions for an inexpensive new look for your bathroom floors.


Step 1 - Clean the floor thoroughly with the TSP or ammonia mix cleaner to remove any built up grease and grime.

Step 2 - Sand entire floor with the 220-grit sandpaper to scratch the surface, creating better adhesion properties. Don't sand too hard, this is just a surface sanding, you don't want to create any pits or dips in the floor.

Step 3 - Wipe carefully with a slightly dampened cloth to pick up the sanded floor dust. Be especially careful with dust collection around the edges of the room. Find an old paint brush to pull out the accumulated dust in the corners or space between the floor and moulding. Painting grit into the floor can effect the finished look.

Step 4 - Apply the liquid deglosser to help with the floor paint adhesion.


Step 1 -  Cover trim edge with painters tape to protect molding.

Special note: If you are feeling uncomfortable about painting your floor, paint a 3' square piece of foam core and place it on the bathroom floor for a few weeks to get an idea of how it will look. Be brave and experiment. Using other foam core pieces, try different colors, a damask pattern, stencils and faux textures to create that  perfect look for your bathroom floor.

Step 2 - Prime the floor with the Latex stain-blocking primer. Paint the wall trim area first then do the central floor painting with the roller. An extension arm works best for limited bending and will provide a smooth, finished look.

Step 3 - Allow primer to dry completely. Refer to package guidelines for suggested drying times. Rushing this phase of the project will only lead to frustration later. Now would be a good time to pull in some sort of fan to either direct the paint fumes out of your home or just get the air circulating a bit more efficiently in that closed space.

Step 4 - Paint the color coat with the latex floor paint product, again using a roller.  Floor paint contains a harder binder than the standard wall paint.

Step 5 - Allow to dry thoroughly, again, based on manufacturer's instructions. Finish by painting 1 to 2 coats of the clear polyurethane to protect the finish.

Step 6 - Minimize traffic up to 30 days since the floor will need time to cure.

Keep in mind that you will need to re-apply the polyurethane coating to the floor yearly to preserve the floor color quality and continued wear protection.
