TSP can cause irritation if you get it on your skin or in your eyes. Be sure to read all the safety information before using, and keep it out of the reach of children. If you don’t want to use TSP, you can use regular soap and water instead. However, it might not clean as thoroughly, and you may have to scrub a little harder to get rid of dirt and grime.

If there are any moldings around the wood paneling, lightly scuff them with the sandpaper as well. If there’s any dust left over from the sanding you did earlier, vacuum that up or wipe it away with a damp rag before painting.

Adding spackle will help disguise the wood panels more and make it look like a drywall wall.

If your wood panels are dark, you may have to use 2 coats of primer for full coverage.

To ensure even coverage, go for latex paint.

You can find pre wallcovering primer at most hardware stores.

Most wall liners are designed to have wallpaper plastered over them, but some are paintable. For most walls in good condition, a medium-grade (1200 rating) lining paper is a good choice. Patterned wall liners are available, but most are plain white.

If your wall liner is not pre-pasted (it will tell you on the package), simply brush a thin layer of wallpaper paste onto one side of the wall liner.

If your wall has any outlets or light switches, use the box cutter to cut around those as well.

Most wall liners need 24 to 48 hours to dry.

Most wall liner is made for wallpaper to sit on top of it, but you can also get wall liner that’s made for paint.

This thickness is also much easier to work with and carry, especially if you’re working on your own.

It’s important to find the studs before attaching your drywall—otherwise, your wall won’t be very sturdy.

A screw gun is similar to a drill, but it’s made specifically for driving screws into walls. As you screw into the drywall, press it flat against the wall to ensure there aren’t any gaps. If you notice any gaps or places where the drywall isn’t attached very well, use drywall nails to tack it down to the wall.

You can also use wallpaper to cover up the drywall.
