Do I need to sand the bed before adding a coat of polyurethane?

i would recommend sanding only the surfaces that will show. as i recall, the rougher spots on the alder will stain a loi darker than the rest, so you want to achieve a very uniform color on the surface.

The wood is very smooth and it could be fine without polyurethane. We did put polyurethane on, and as Gennaro says below, you need two coats and should lightly sand the first coat before putting on the second. So you don't need to also sand the wood.

No, the wood was very smooth, however you will need to sand lightly with a between coat sand paper (I used 400 grit) between coats of poly, remember to use a tact cloth (available at any hardware store) to remove the dust and achieve a professional finish.

We didn't sand it, but the corners can be a little rough. I would sand the edges and corners if I had to do it over. We do love this bed. Especially because it is made of solid, chemical free wood and because we were able to finish it ourselves with non toxic stains. It looks great and I don't have to worry about the bed off gassing toxic chemicals in my son's room.

No! DON'T EVEN THINK ABOUT THAT? Use sanpaper, starting with 200 grit. Finish with 600 grit. If it is real bad gel coat, consider filling gouges weth gel coat, sanding andpossibly reshooting gel coat in real bad areas. Always sand out finish and polish with non wax fiberglass polish.

I really don't know, but I will say this... it is ALL ABOUT THE PREP. Some of my cabinets needed sanding, some were fine with the product they provide in the box for use with the scrubbie pad. If I was going to try it on a veneer I would probably sand.

Didn't sand ours, but it is a little rough. At least 2 of the boards split upon screwing in, too. It's an OK bed, but nothing fancy for sure.

Yes, if you follow the correct procedures for application. The work depends on how the surface absorbs the polyurethane. When I used it on oak, it took three coats sanding lightly with 220 grit sand paper between each coat. Use a tack cloth or clean damp cloth to wipe all dust off between coats. Best applied with a foam brush. Do not place in direct sunlight on a hot day to dry or the finish will bubble. And have fun!

Yes but you will have to paint/stain over. Product is can be sanded smooth.

I added extra polyurethane onto the top myself - three coats, But I still use placemats anyway. I have set stuff like glass of iced tea down for short time and it did not leave stains, etc. ( after adding the poly ) Note the poly I added is just a bit rough in a few spots, but I'm not a carpenter or furniture refinisher :-)

Not sure. I believe it should be correctly sanded before using. My process was strip, prime, wet sand, prime, wet sand, clean, paint ( at least three coats) ,sand between coats, paint should look dull. Clear coat, sand, clear coat, sand. Rubbing compound, buff, polishing compound, buff. I did my motorcycle gas tank like this and my friends thought it was professionally done.

You would definitely want to add a finish. Although the wood is sanded to smooth it, it's bare plywood.

I would think so. I went over a stained and finished bedroom set. No sanding required. Sanding left scratch marks in the finish which showed through the gel stain.

I did not sand mine down and they were fine. I did use TSP, rinsed well and then used windex to get any leftover residue. So far paint has adhered very well. The brush that comes with the kit is amazing but I used an artist brush to go around the hinges so I didn't have to take off doors.

Yes, you do. THis is not a self-etching formulation. Therefore, it is very important to scuff as well as remove all residues properly from the bed. Remember, you have wax and other chemicals built up on the surface of even a new truck. A Spray-Lining Formula would burn right through the paint of a new bedliner which U-Pol does not make. I would use a medium grit sandpaper.

Im no expert here but i would think if you did a light sanding beforehand it would be alright.

I would think so. The adhesive isn't terribly sticky though so painting that first coat might be tricky. I would make certain that if you're sanding first that you clean the dust residue well to ensure the best adhesion prior to coating - and if possible float on the coating rather than painting. I would just be concerned that some of the finer details might get moved by brush strokes.

It depends on the look you are going for. Some of the pieces are quite rough and do benefit from sanding. They do recommend oil, and some pieces have a lot of oil already on them. But I wanted a more durable finish on it that would be easy to clean, and since I do not use the top to prepare food (I have a great big cutting board for that) my husband went with a polyurethane finish. I love it. It is very smooth and well protected. It is also easy to clean.

You could, but if it's for a large area like a whole room it would take a very long time. If you plan on refinishing the floor you will end up needing to sand it smooth anyway after using this tool. So may as well use a floor sander right from the start. Depending on how much paint you are removing you might need to use a chemical stripper to remove the bulk of the paint before any sanding.
