Hello there:


I should probably know the answer to this question - so sorry in advance for block-headedness....but....


I posted a question here earlier about how to prevent bleeding between the above-waterline section of the hull on my HMS Blandford (stained) and the below waterlne section (painted tallow).


I got a great description of a process from Randy (RNBrook). There he suggested that I first apply stain, then coat with a few coats of polyurethane, allowing this to dry thoroughly. Then sand with 320 grit paper. Then apply paint. Sounds good to me and this is the way I would like to go.


Here's my question - the paints I use are Golden artist paints (acrylic), while the stain is (obviously) oil based....so - do I use an acrylic or an oil-based poly? I'm assuming acrylic (for the sake of the paint) but will this have any adverse effects on the finish of the stained sections?


Again, I feel myself getting dumber even thinking about this question, but if anyone could set me straight I promise to be more thoughtful in the future! Thanks,

Hi Hamilton,

Oil based polyurethane.This goes over the stain, and the acrylic paint will go over the poly.The Oil based poly acts as a barrier coat between stain and paint.In the UK they are labelled either acrylic or polyurethane varnish.The acrylic based Isn't a true polyurethane.

Kind Regards Nigel.

I would not use acrylic over oil based polyurethane. It can scratch off easily.

I have never had a problem,however I always spray another coat of polyurethane over the lot, colour included,far more durable than acrylic on its own.
