CHINESE DRYWALL CAN CAUSE PROBLEMS

Recently I discovered that Chinese-sourced drywall can cause off-gassing, leading to corrosion of metal in the house structure and components. This was primarily an American issue and I have not heard of it in Canada.

If the metal in your house turns black, you may have this drywall installed. The corrosion can attack copper pipes, metal studs and the metal on faucets etc.

TILE BACKER BOARD INFORMATION

I choose this product because it will not absorb water. I did a control test leaving a piece of the material outside for two years and it did not deteriorate or mold. I love this stuff!
