This will stay around until the glue, prep boar trim and marble are done off-gassing. A typical air purifier will not even touch these gasses, so you need to. Just rough up the surface for the glue hang on better.
Hi cam, I m gonna guess this is likely cultured marble slabs, rather than real marble, but I may be wrong. Regardless, at a minimum I would paint on Redguard or similar waterproofing membrane to help as a vapor barrier. Cultured marble offers a palette of designed veining and color options. Once cut to fit, installation of cultured marble consists of gluing the marble in place and allowing the adhesive to dry.
Formulated for adhering marble , granite, quartz, solid surfaces and other similar materials to most common construction materials. Acetone is best to remove dirt or oily substances from the surface of the marble. If you don’t have acetone available, use detergent.
Epoxy glue comes in parts which are mixed together before gluing. Acetone is used to clean the back surfaces of the products prior to install. IMPORTANT – use Acetone only. Denatured alcohol or other water based cleaners are not acceptable. The cleaner the surface, the better the material will adhere.
Once the cultured marble has been cut to fit your surroun test fit each panel in place. Begin with the back panel of the shower and then the two side walls for the best fit.
