Need some help fixing up my hollow doors!

There are many adhesives that will hold w/o clamping or nailing. I like Elmer' Pro-Bond, available at home centers or hardware stores.. I would lay the door flat, place the mouldings on the door and pencil mark slightly INSIDE. Sand, or liquid sand, to remove gloss. Apply the mouldings with masking tape for a "dry run." Follow the adhesive instructions and tape down for real. If you have ready access to a brad gun, tack the moulding but not absolutely necessary. You are right, nailing alone will not hold in the 1/8" veneer, but a few nails will somewhat increase the holding power.

I would take the doors off their hinges and lay flat. Have all your trim pieces cut and ready. You can use liquid nails to attach to the door. I would tape them in place with painters tape just to make sure they stay in place while they dry.

As a retired carpenter, I have fitted trim to doors many times, it is quick, clean and the best method, all you have to do is apply double sided tape to the trim, position it on the door and press down, no wet glue or waiting to set, it is instant just practice on a bit of scrap, when you put the tape on the trim, peel the first few inches off and fold over at a angle so that when you put it to the door you can pull the backing off and push the trim in position. Hope this helps

I have glued trim on doors before. but after reading david's comment I'm wondering if I should have been using double sided tape.

I use this product and it works well and fast too. It's by Liquid nails and its called POWERGRAB It worked so well my husband though I got into his tools and nailed it up. I put trim around my closet on a textured wall and its been up for a year no problems so far. Good luck Teresa

I would use a fairly strong glue,trims are usually very light weight so should adhere to your door.

I set up my router and made random grooves, added recycled fence boards along the top and bottom, then painted everything to look like barn wood. Finished with black oak-tag to resemble hinges, black tacks to attach, then added some old knobs. The doors hide the washer and dryer.

U can use liquid nails on it

I have also seen picture frames used on doors. Find 4 to 6 flat frames, depending on the look you are going for. No sawing or fitting trim, just measure and glue, then paint.

You only need to use a decent white wood glue. Try using a coloured stain instead of paint so that you see the grain coming through. Have fun!

If it was me, I would use glue and a brad nailer. But i've got a brad nailer... It sure would be faster...
