I measured a very nice large home on Friday. It's going to have a wide plank LVP throughout. After drawing the layout, I went around with my 6' angle aluminum straight edge..... Oh dear The slab has 1/4 inch wide saw cuts about 10 feet both directions. Some may have been separate pours. Where they meet, some edges have curled up a little or one side sunk a little bit. The home is 36 by 75 and only 45' is concrete. Where the wood framing and concrete meet up, it's fine. The slab joints... Read more ..read more

I have done a lot of research about concrete and how it's possible to finish it. I did a quick water droplet test and the concrete does not seem to absorb the water, the drops pool on the surface for a long time, maybe 20 minutes. Specific questions: - Would staining the concrete be an option (to avoid paint, which I've been warned about many times)? If so, do I need to etch the surface before staining it? - If etching is necessary, what's the safest / simplest way to do it, since it's not... Read more ..read more

I'm considering sanding down these swirls and restoring the shine by progressively using diamond resin pads of increasing grit levels. However, I'm concerned about potentially altering the...

I'm trying to decide whether to redo a gypcrete floor underlayment completely or just repair what I can and go with it. We have a third floor condo that flooded, the living room floor now sags about two inches to the center. It was inspected and is structurally ok. The gypcrete that is currently laid down is intact but softer than it should be. To contract a company to come repour the entire floor, they want $5350. Or I could cut out the areas that are sagging the most and fill in the worst... Read more ..read more
