Sanding Sealer
Posted by cprfan on Tuesday, December 5, 2017 1:36 PM

I used to build wooden kits like the Ambroid kit built in the December MR. I was looking forward to reading some modern tips but there weren't many. One tip I was looking for was sanding sealer. I can't find such a thing anymore. I used to use model airplane dope. That's gone the way of the dodo bird. The article shows him applying something from a can but doesn't tell what he used. I'd like to know.

Most of the major paint manufacturers have a sanding sealer.  I have used Minwax in the past.

Basically though, whatever you are going to use for the finish coat, can be used as a sanding sealer.  Every coat you put on, fills just a little more.  Lightly sanding between coats smooths/levels it out.  Just keep doing it until you have the desired finish, and the wood is filled in the way you want it.

Pretty much repeating Mike:

 

When I worked with wood model railroad kits, for sanding sealer I just used whatever leftover paint I had.  I stayed in brand, Floquil, in this case.

I saw that on their website but it is a different world here in Canada. The local guy who sells all kinds of Minwax products looked at me funny when I asked for sanding sealer. I work in acrylic now so I'll try something from the craft store.

My LHS, which doesn't have much in the way of trains, DID have clear dope.

I would suggest a thinned Mod-Podge or similar acrylic medium.

Try shellac.  Available in hardware stores, dries fast, thins in alcohol.  Accepts anything as a top coat.  Give it a coat.  Sand it a little bit, give it a second coat, and you have a good smooth surface.

Try shellac.

That is my suggestion as well.

https://www.rustoleum.com/product-catalog/consumer-brands/zinsser/primer-sealers/b-i-n-shellac-base-primer

There are several brands, Kilz, B-I-N, Bulls Eye. The pigment will help fill voids in the grain and it is easily sandable after drying.

 Mod-Podge? I'm not sure if the sanding qualities of this would be very good. I think it is a PVA based adhesive, like Elmer's glue, and may not take paint too well either.

I could be wrong on that.

Good Luck, Ed

My thought as well, but you could also use a slightly thinned dregs in an old pint of polyurethane or varnish you have lying around.  The idea is to have it penetrate a bit, fix, seal, and then lightly buff as a sanding procedure prior to the finishing coat. Maybe repeat as necessary prior to that finishing procedure.

I had a similar inquiry quite some time ago and it was suggested I use water based latex (white) paint.  I plan to do so on some 7 Ambroid kits I have ready to go.  The old hobby shop "Sanding Sealer" worked very well in taking out the grain appearance but I also believe several coats of the finish paint with light sanding will also work.

Hi guys,

Sorry for leaving that out.

I found Minwax Sanding Sealer at Home Depot. It's acrylic, so easy water clean-up.

The paint guys there didn't know they had it.
