Yes, with these limitations: Tile must be installed per installation standards published in the most current TCNA Handbook, ANSI 108 specification. And if the OSB is weather-beaten or delaminated, it must be properly overlaid with a cement backer unit or an additional layer of subfloor.
For homeowners and building owners, the advantage is after installation. MAPEI’s BioBlock products will not support the growth of mold/mildew/fungi – with adequate cleaning and maintenance practices.
The advantage for contractors and installers is that MAPEI’s BioBlock products do not support the growth of mold/mildew/fungi – with adequate cleaning and maintenance. Therefore, their use can prolong the life of an installation, resulting in fewer callbacks for installers and contractors.
Since the introduction of the BioBlock logo in 2003, MAPEI has continued to develop and expand the range and depth of products that include this technology. The list of MAPEI products that carry the BioBlock logo is evolving with the technology and is constantly growing. Look for these innovative products across the following categories: Liquid membranes, adhesives, sealants, caulks, mortars, grouts and finishes.
The type of stone, tile and grout that you have will determine if sealing is necessary. Glazed ceramic and porcelain tiles have almost no porosity and are highly resistant to staining; therefore, sealing is not required. However, it is beneficial to seal unglazed, polished porcelain floor tile. If either the tile or grout is considered porous, such as natural-stone tile, terra cotta, Saltillo, brick or cement-based grout, sealing is recommended.
Although not required, for optimal results, Ultracolor Plus FA or Ultracolor Plus Max may be sealed - especially in places such as showers. Sealers make grout maintenance easier in the long run. The solution: UltraCareGrout Sealer.
