That sunroom vinyl job taught me to always check for dampness first

I installed vinyl planks in a sunroom last week, but the edges curled up after a few days. The concrete slab was wet from a leak, so I dried it out and redid the job. Now the floor is solid. How do you handle moisture problems?

Moisture issues aren't always a deal-breaker for vinyl! I've installed planks in slightly damp garages and they stayed flat. Using a good underlayment or sealant can make a big difference. Maybe the problem was the specific leak, not general dampness.

Even with sealant, sunroom heat can still make vinyl edges curl.

Moisture meters are cheap and save so much hassle... I test the slab in a few spots and let it sit for a day. A leak is different from general dampness, but both can cause trouble. Sean854 has a point about underlayment helping with slight dampness, but a wet slab needs to be bone dry first. After a leak, I'd run a dehumidifier in the closed-up room for at least 48 hours before a retest.

Forget sealant, wet slabs always ruin vinyl eventually.
