I would like to give the exterior a freshening up, after I fill the checks and seal it up.
I like the fairly natural colour that is on, and with the exception of a bit of wear and fading it looks pretty good.
My question is can i use a water based stain (looking for a lower VOC) over the house if it was previously done with Cetol?
Thanks everyone for your help,
Call Sikkens, but I'm pretty sure they'd tell you no. In general, it is a bad idea to mix technologies (oil- vs. water-based) that way, and here's why: water-bases are usually more elastic than oil-bases. If you put the more elastic product over the less-elastic product, one will pull at the other and could lead to peeling. We've seen it happen when people have used our Cascade clear coat (a water-base) over other oil-based products.
THAT SAID - It's quite possible Sikkens has come out with something that is lower VOC and/or water-based that you CAN use over their Cetol product, so I'd call them. Manufacturers often try to come out with products that are designed to work within their product line, so they just might have something for you.
Hope that helps!
