Smile Slab Temperature

I am ready to lay an engineered Hickory floor using Roberts engineered flooring mastic on an above grade concrete slab. Floor is clean and level.

Mastic directions say that slab must be 65 degrees or warmer for a prior period of 72 hours.

This does not seem practical because the slab is laid on bare earth which is cool. Can I lay the floor on a slab cooler than 65 degrees?

Welcome to the forums!! Have you checked the temperature? You are assuming it is below 65. I would bet it is closer to 72, which will feel cool to a 98 degree body. Geothermal temperature will stay close to the 70 degree mark much of the year round. Let us know what the temp is.

Thanks Chandler... that's a reply with insight. I'd like to take the slab's temperature but it refuses to lift it's tongue. Says that it's set in it's ways. Maybe I can take a masonry bit and drill a hole in the slab, fill the hole with water and then insert a thermometer.

Any other ideas or suggestion?

Sounds like something you might wanna use if you have a pet gorilla with a fever.

Or an ornery MIL, but I digress. You can rent one most likely for cheap, but owning one is better. It looks good on the tool wall, anyway!!

Find a piece of Styrofoam insulation around 12" x 12" at least 2 inches thick, carve out a portion of the center only enough to hold the probe of a thermometer.
Place the Styrofoam on the floor with a weight on top and whatever reading you get will be the floor temperature.

Great idea. I like it! Now I've gotta put my hammer drill and bit back in the shed.
