Sunroom #3: false alarm

« Part 2: Slow progress... Part 3 of Sunroom series Part 4: SLC the only way.... »

so I got around to checking the concrete slab in the sunroom this afternoon and it appears I am at a full stop until I figure out how to either a)remediate or b) if it’s not worth the effort and take the flooring back. I bought a moisture meter at Lowes – just a simple one
as well as a 3/16 concrete drill bit. I drilled 1/4 in. deep holes in three locations in the slab – one near the back door, one close to the step into the kitchen and one at the corner opposite to both to form sort of a triangle.
The results were 21%,12%,and 9%. I’m guessing the adhesive that is still down from the exterior carpet does a pretty decent job of blocking the moisture since the surface reads I took were only 3-5%. Do I just put down plywood with tap con screws…or is that just giving it one more layer to get through? I don’t have long to sit on this decision though with the holidays coming quickly and the need to compete this project. Never a dull moment, right??

EDIT: I grabbed the installation instructions on the floor again -

A moisture test is strongly recommended to determine if high moisture exists in the subfloor. When using a calcium chloride moisture test for concrete subfloors (ASTM 1869), values must be ? 5 lbs/1000ft²/24-hr or <80>s less than 3/16 out of flatness/level.

You still need a moisture barrier between the cement and wood. I use 6 mil plastic or 30 lb. felt. The cement may be dry now but depending on what is poured, the stuff can be very porous. That moisture will rot the wood and attract a bunch of critters from termites to ants. I would also seal the cement.

hm – looks like it cut off the last part of my post – oh well :) Thanks DB! I have a 6mil barrier on hand to go over the concrete, under the laminate. I’ll see if I can locate a sealer – it has carpet adhesive over most of it which seems to act as some kind of barrier already. I don’t honestly want to go at it with an angle grinder or floor sander unless absolutely necessary.

The existing adhesive may be fine.

Thanks DB! Went to HF yesterday and got a 72in level to check for flatness. Thought I was good to go until I hit a spot that’s up to 3/4 to high/low. Checking to see how big this spot is and how big of an issue it really is
