Installing a Sub-Floor over a Concrete Basement Floor - June 27th 2002



Question from Ron in Campbell River, B.C. -----

Dear Shell,

In the basement of a 40 yr old house, I want to rip up the old carpet and put a sub floor down and recarpet, should I place some kind of poly on the concrete floor 1st before I put down the sub floor and are there any other considerations I should be aware of prior to undertaking this project.

Thanks,

Ron

Dear Ron,

I might tackle your project like this:

1. Wash the floor with Shell Busey's Home Cleaning Formula.

2. Rinse well and allow it to dry thoroughly.

3. Apply Cloverdale Paint Aqua Seal using a low-pressure sprayer.

4. Lay down Delta FL Floor Membrane available through TimBrMart or Home Hardware Building Centres or call Basement Systems @ 1-888-379-3456.

5. Apply or 5/8 plywood over the Delta FL.

If you follow these steps, you will end up with the best thermo break sub-floor you can achieve when you want to steals just 1 inch of headroom.

Its Just That Easy
