I'm looking for suggestions for a floor covering for our screen porch. Here's what we've got:
The contractor told us it was a new kind that is weather proof. I was skeptical but trusted his judgment. Not so happy with it now. So I'm looking for some suggestions on what I can put down over it. Carpet doesn't seem like a real good plan. I figure it'll get wet when it rains in and just hold the moisture against the OSB. I looked into those vinyl floor planks. They looked promising but this is Minnesota where temps can be 20 or 30 below zero in the winter and up around 100 sometimes in the summer. The manufaturer of the vinyl planks says they're only for temperature controlled environments. If would be nice if the surface was smooth so it can be cleaned with a mop--I don't want to pressure wash it.
- The existing floor is treated OSB glued and screwed to the joists.
- The floor is level. Well, except where the edges of the sheets swelled after getting wet.
- There's no more than 3/4" between the OSB and the underside of the sliding door threshold.
- The siding on the house was trimmed right down to the OSB. Not fun to pull the siding off to put flooring under it but maybe we'll have to.
- The floor is held back about 1/2 in. from the exterior walls to allow water to drain off. Of course being flat, the water doesn't do that anyway.
- We plan to put car siding on the inside of the walls and leave it up off the floor a little.
- the porch is 12 by 20 feet.
Is there some sort of thick, somewhat flexible, durable coating that would go on reasonably smooth? Any other suggestions?
Thanks in advance.
