LowMoFo Posted August 26, 2019 Share Posted August 26, 2019 Hi all, STILL in the midst of a build, and unsurprisingly, having some more issues... I have an ash body, which I stained, and was immediately very happy with. I also really like the grain texture so decided not to seal it as I would lose the texture, and risk sanding through the staining. Both no-nos in my head. I want the grain visible in the clear-coat. I've opted for polyurethane as it's harder & less harmful than nitrocellulose. However. I have a few areas where the grain is so open, it has (somehow) caused a reaction when clear-coating. This has happened twice now. I've stripped the poly away so now I'm back to the spirit stain, and there are, in these open-grain areas, bare spots. Any & (so far) all attempts at re-staining these areas result in the wood slurping the stain away. The obvious answer is to seal these rogue spots, but I'm at a loss as to what kind of sealer to use with polyurethane clear-coat. I've been all over Google, with no answers. So, learned low-enders, should I:- Just keep hitting these bare spots with more & more spirit stain, or apply some poly to the bare spots, key these spots, then go over with stain, prior to clear coating? I really like the burst on the front, so really don't want to start from scratch. The back is stained a solid overall mahogany so provided the poly 'seal' accepts stain on top, hiding these patches should be ok. Right? I'm getting super frustrated with this, so am desperate for a solution. Please help!! I thank you in advance. Quote Link to comment Share on other sites More sharing options...
durhamboy Posted August 27, 2019 Share Posted August 27, 2019 For many years I've regularly used blonde shellac (or ordinary amber shellac if preparing for a color coat) as a sealer coat, as it will take just about any final finish, nitro, poly, acrylic for cars etcetera. A couple of coats of shellac wiped on is super thin and shouldn't affect your planned textural finish. Might just solve your problem. 1 Quote Link to comment Share on other sites More sharing options...
Dov65 Posted August 27, 2019 Share Posted August 27, 2019 I'm no expert m8..far from it but i think you'll have to grain fill first then sand & reapply stain, another method i read about was dewaxed shellac & meths mixed together as a washcoat for sealing prior to stain Shuker done this on a build thread on here. Possibly tint your poly with stain ? Quote Link to comment Share on other sites More sharing options...
