Sikkens Interior vs. Exterior Finishes
I am about to finish some exterior doors with Sikkens clear (Cetol 1? -it’s at the job site). I have only been able to find the exterior product and the local stores have never stocked interior.
I’ve been told that the only or main difference is the interior is harder to hold up to cleanings and resist stains better and the exterior more elastic to withstand wood movement outside.
Since I’m finishing an exterior door should I use exterior on both sides? It’s actually an accordian “slider” so will be exposed to exterior quite often.
Will using an exterior on interior surfaces in general cause problems down the road? it’s it really that bad of an idea and some thing to avoid absolutely?
I really like the product as it seems to brush and lay down very nicely, WAY better than any others I have used in the past and this is a plus for me.
