I’ve done it every which way ’til Tuesday. Rubber mats, Red Guard, etc. etc.
But I like this method the best. The three “F’s” of skim coating:
FRUGAL: $50 all in. Durarock is relatively inexpensive, easy to cut and lay down. $8.00 – $9.00 for a 3’x5′ sheet. A bag of vinyl cement is well under $20.00.
FORGIVING: Well mixed vinyl cement is easy to trowel and works its way into cracks and mistakes like nobody’s business.
FAST: All this takes about 20 minutes (and is actually kind of fun!).
Here’s how we prep our cement:
Here’s how we prep our floor:
Here’s how we lay it down:
Here it is “Finnished.”
This has worked great for me for about 10 sauna builds. My cabin sauna is 23 years old. I found a crack in my floor and simply mixed up a little vinyl cement English milkshake consistency, poured it on, and filled the crack. And that was 7 years (and 348 saunas) ago.
Once skim coated, our floor is ready for duckboards or a suspended wood step.
All good on this Western front.
If there’s a better way to Finnish off our hot room and changing room floors, i’d like to know about it!
