Varathane over stain…required?
Ok guys. I’m sorry, this is not really a “green” building question, but there is such knowledgable members on this forum I had to ask…I can’t seem to find a solid answer anywhere! Plus it deals with VOC’s, so thats green based 🙂
I have douglas fir 6×6 beam and 1×6 t&g. 50% will be used indoor, 50% will be used outdoor.
We stained the fir with a oil based stain labeled as “interior and exterior”. I could not find a water based “exterior” based stain and liked the idea of using the same for all to keep the color matching.
The wood is sandblasted so its really rough (to make it look aged).
My question is…do I “need” to use a varathane or similar top coat over the wood? I can see it providing protection for the exterior use (its under a soffit so it won’t see any sun) but for interior is it needed?
Is there any sort of VOC protection by using the varathane over-top of the stain, to sort of “lock in” the VOC’s of the stain? (this is more relevant for the interior areas)
The varathane I’m wanting to use is “Diamond Wood Finish Water Based”
Looking forward to the kind advice 🙂
