blasting the floor, an expensive, time-consuming subcontracted pro- cess. New primers, like TEC Multi- Purpose Primer, just need to be applied to the substrate, allowed to dry and the concrete is ready for the tile-setting process. When crack isolation and/or water- proofing are needed on concrete or other difficult surfaces, the required membrane can be installed directly over these advanced primers. Always review the manufacturer directions and recommendations for use of the priming products. As tile contractors discover the capabilities of new primers such as TEC Multi-Purpose Primer, old meth- ods and many surface prep steps are being eliminated. These primers can offer additional benefits for the tile installation. For instance, TEC’s product improves the adhesion and bond strength of TEC leveling prod- ucts and works on both porous and non-porous sub- strates. As today’s tile-setting tech- nology, the game- changing priming products give contractors the oppor- tunity to save prep time and money by eliminating labor-intensive steps without sacrificing the quality of the installation.
