Premium modified mortar contains latex which provides a stronger bond over unmodifed mortar. modified mortar will also adhere well to wood substrates. we have tested this with ttmac and tcna along with mortar manufacturers and they all recommend premium modified thin set mortar.

10” from the end and 16” on center.

16” from the long side and 30” from the ends.

24” from all sides.

Yes you can but it is important to remember that the bond from the tile to the provamat is stronger than the bond from the prova-mat to the substrate within the same day. If you have to remove the tile in the same day, it might pull the prova-mat off the substrate which will create a loss of bond. same thing is true for the prova pan. You cannot walk directly on the prova pan with the prova-mat pan liner immediately after installation.

Prova-mat should be allowed to dry at least 12 hours before tile is installed to avoid loosening bond.

Note: prova pan should be protected at all times until tiles are installed and set.

Yes, but try to cut equal amounts off both sides if at all possible.

You can either purchase our extension kits or fill the space with dry pack.

It is a sand and cement mix purchased where you buy your mortar. mix it with just enough water to form a ball, which holds its shape.

No problem at all. mortar takes 28 days to fully cure but in 7 days it is 75% cured. if you try to pull it off after 7 days it will be hard to do, and in 28 days you will hear the scrim tear apart. The area that was peeled back must be refastened to the wall with fresh mortar before you install the tiles.

A minimum size of 2” x 2” tile can be laid in the prova pan. any smaller might get crushed with heavy weight. for any tiles larger than 3” x 3”, install the tiles to honor the axis lines along the pan. this will ensure the tile installation travels along the planes of the pan without peaking up along the corner.

Yes, they do not get hot enough to cause a problem. You can install prova flex-heat over the pan, insert the heat cables, and cover the assembly with prova-mat to avoid water pooling in the cavities of prova flex-heat.

The base can be poured (drypacked) instead of using a foam pan. Simply follow the prova board plus installation instructions starting from the prova pan assembly and omitting the foam pan. All other steps apply to this type of installation.

Note: concrete base should be cured and dry before covering with prova mat. drying and curing times of concrete bases vary depending on climate conditions. prova-mat must be installed on the shower base prior to the installation of prova board plus.

 Unless it is a stainless steel product, it is not recommended for outdoor use, as it will change color due to oxidation. 

You can use a miter saw with an 80+ tooth blade, or you can use a hacksaw. Tin snips are helpful for cutting the flange (the part that doesn’t show).

Yes, you can paint these products using a can of spray paint.

Stair nosings are secured using a combination of premium construction adhesive and flat head nails.

 No, these products are not UV stable. They will not stand up to the elements. 

For the smaller trims—stair nosings, reducers, and caps—you should use contact cement/tape. For larger profiles—stair treads and equalizers—you can use a vinyl adhesive applied with a notched trowel, or you could use contact cement/tape as well. 

Depending on the profile, you can use tin snips, a knife for the smaller trims, or a saw/miter saw for the larger items.
