Hey guys,

Finished a project with water based Varathane high traffic. Everything is good but I’ve found out the surface may be exposed to materials with heavier staining properties and just harsher treatment in general than I planned for. So now I’m a little worried about the durability of the varathane.

Could I put general finishes high performance over it if I prepped the surface or should I really consider putting a clear oil finish on top? If oil is the best answer, do I need to wait for the varathane to completely cure before putting oil over it? I know that can be several weeks.

Project is an interior piece. Thanks!!

What are the environmental concerns?

Candle wax, turmeric, and some kind of vermillion powder. At least that’s what I could see being used currently around what this is replacing.

I would certainly think the high traffic stuff would do well with abrasion but trying to offer protection from that environment could be tricky, I’d contact Varathane directly and see what theory had to say.

It sounds like this is some sort of “work” counter.
The varathane will take a lot of wear but serious staining products may penetrate it.
I would consider a black plastic laminate like they used in chemical labs.

What made you conclude the HP is going to fare better than the Varathane? Just curious. Personally, I don’t think any durability difference will be measurable between the two.

Hey Fred,

Well honestly I just figured GF is a good brand and at over twice as much for a quart of the stuff it should have magical properties heh.

I don’t know the answer to your question but I wouldn’t fix it unless it breaks. Switching up finishes often leads to trouble. Just use an extra coat or two of the original varathane. Or don’t, and wait and see if it’s a problem.

Any idea what those staining properties and harsh treatment might be? Sort of pointless to contemplate changes without knowing the specifics of what you’re trying to counteract or protect from. Then Varathane can guide you with a specific solution. You might even be fine as you are.

Hi Pyro
Welcome to Ljs
Anytime you want to place one finish over another you can run into compatibility factors so to play it safe you can put a coat of dewaxed shellac over the first layer and any finish will stick to it, that’s one of the great things about shellac.
