Had to pick between a full glue down or a floating floor for a big basement job
The client in Greenville wanted luxury vinyl plank in their 800 square foot basement, which had a concrete slab with a few small cracks. I was worried about moisture and the slight slope, so the choice was a full spread adhesive or a floating install with a heavy underlayment. I went with the glue down method, using a moisture barrier primer first and a trowel-on adhesive. It took an extra day to set up and dry, but the floor feels rock solid now with no hollow spots. Anyone else lean towards glue down on questionable slabs, or do you trust a good underlayment more?
