Guest guest Posted July 18, 2010 Report Share Posted July 18, 2010 I just got the following message from a friend and fellow mold avoider. Best, * - Yesterday while at Home Depot I discovered a huge stack of HardieBacker Cement Board Tile Underlayment, which is in extremely common use under ceramic tiles, wet and black with mold! The Home Depot flooring guy admitted that HardieBacker Cement Board Tile Underlayment does contain cellulose ( " mold food " ). (By contrast <cement> Wonderboard and <plastic> Ditra are cellulose free.) Amazing, our tile guy was considering HardieBacker Cement Board Tile Underlayment as an option for our kitchen! -Rock Quote Link to comment Share on other sites More sharing options...
