Hi there,

I on the advise of several sales people and a designer I bought br111 7/16 indusparquet, solid Amendoim. I think it is a type of oak from Brazil.

Anyhoo, I was assurred by Home Expo and their installers it would go fine on top of my cement slab w/o a plywood subfloor. The manufacturers website says it is fine too with simply using a specific sealer and adhesive.

However, I have had 3 hw floor installers run out of my house cause they say it cannot be done. Whats the deal? I live in sunny and usually dry Southern cali so moisture in the house is not a problem.

They ran out of your house, because solids over concrete are a high risk installation. There is a very fine line, you walk when you take on an installation like that. I guarantee the floor to cup eventually. Not immediately, but it will, even years later. All it will take is for the slab to hit a dew point. Sealers have nothing to do with dew point moisture

I run from those also. Just because i have inspected enough of then to know better.

Do concrete moisture test and document that with pictures and written documentation. Use the StatStuff sealer as they warranty it, then the StratStuff adhesive.

This way when it buckles and cups serverly, you will have the documentation and pictures to prove their inspector wrong.

Anybody ever use that stuff? Never seen it. It's always Bostiks with BR111. Even the first distributor to bring BR111 into the USA doesn't hardly keep any around.

Dry southern CALI>? Not from what i've seen the last few months--good luck out there!!

Remember, it's not the heat, it's the humidity!!
