Mobile home walls-how to paint them and how to hang heavy things?

I use sheet rock nails with build in support and around the windows my husband install wood flat boards at the top from studd to studd ,Then I hung my curtains ( I Stan or painted the board first)

Always start painting with a good quality primer to seal the "plastic paper" on the walls.

This means you need to make the walls heavier as the cheap crap they are made of won't hold anything. The answer is to coat them in pallet wood, giving you both a better wall and something that can hang heavy things on.

If you're not doing this on a budget, you can always get wood flooring and attach it to the walls giving you a much better wall.

Pallets can be sanded and painted or oiled and coated with wax. Pallets make really beautiful walls and really improve the value of a trailer. If you're worried about noise, then use an adhesive on the pallet wood to attach to the walls and a hand saw is much quieter than an electric saw. It gives your body a work out too. Little sweat equity. It is pretty to let some of the flaws show through too. A knot hole with a little glass figure or a nail hole with a hook in it for your keys really makes it rustic and useful.

I have seen this done in a V shape, and just diagonal too. Both are beautiful.

I did my floor in my bathroom with pallets and it had a "picture frame" shape to it.. I used a router to give it a tongue and groove fit so they just snapped together.

i take a wild guess at using ''stud wall fixings'' i think thats what they r called for hollow walls. You can knock in put cant pull out as they 'flare' open to stop pulling thru drilled hole?? When you say heavy remember they aren't solid walls so keep it in mind.
