I want to replace my vinyl-phthalates – flooring for something ‘greener’. Can I cover it with plywood ?

Since phthalates are emitted from vinyl tile flooring will covering this flooring with plywood sheets – then putting down new floor covering be sufficient. Or do I need to have the vinyl pulled up ? They can measure the phalates in house/floor dust and in the home occupants blood and urine now. Will sandwiching in these tiles with plywood be enough.

Just do the right thing and take it out. Short cuts always come back and bite you in th a**.
