I am installing marble pieces over old brick around a fireplace opening. The old brick is stable, but not perfectly flat. The mortar joints have receded (flaked off) a bit over time. Should I parge with mortar first, or multiple coats of thin set. thank

Asked by: Tim
A substrate should always be clean, flat, level/plumb, and ready for tile installation- you'll want to make sure this is done as your prep before you install. UltraFlex 1 may not be the best option to use with marble; a better choice may be using an epoxy adhesive after using a primer. Some good choices would be the Ultraflex LFT or Keraflex Plus.

can this be used for shower tile install

Asked by: mark
Yes, UF1 is fine for tile installation in a shower as long as you are not installing large format tile or glass tile. For those installations, we recommend Ultaflex LFT, LHT & Adesilex P10 Mosiac & Glass tile Mortar. Please note that UF1 is fine for intermittently wet areas (shower) but should not be used for submersion in water (pool). Please refer to all manufacturer’s recommendations for installation.

Can I use this with mosaic 1 inch tile on the floor?

Asked by: Kb
UltraFlex-1 can be used on floor for tiles up to 15 x 15. We recommend reviewing the technical data sheet for more information about your specific installation requirements. For glass mosaics we recommend using Adesilex P-10. Please note that if any one side of the glass mosaic is larger than 6in Keraply should be used in place of water.
