Mapei Ultrabond ECO 995 introduced in early 2010 is a combination adhesive and moisture protection application. Benefits with the product offer a one step application with mostClip on trowels hardwood and bamboo floors. Project time and costs are reduced as ECO 995 can be applied with installation immediately following. No more waiting for other hardwood sealers to cure.
ECO 995 is sold in five gallon containers with costs near that of the Bostiks MVP. Recommended spread rates or amount that should be applied will vary slightly on type of hardwood being installed. A general rule of 40 to 55 square feet per gallon can be used for products less than 5/8 inch in thickness.
Another popular two part product is the Bostik Vapor Lock, described by the company as being a one part rapid tacking, moisture-cure urethane adhesive, and vapor retarding membrane. The application is similar to Mapei’s ECO 995, but does have significant differences in spread rates that depend on the hardwood thickness being used.
Both products mentioned above are not a cure all solution for excessive moisture problems or readings exceeding 15 pounds of moisture emission with concrete slabs. Consult with each manufacturer specifications for proper usage.
Another popular multi purpose adhesive is Taylor MS Plus. Similar in the benefits provided with others above, the company also supplies a trowel clip on insert to be used only once or when each container is emptied. This insures whoever is handling the work gets the proper coverage. I consider it to be a great innovation as there are some installers that simply use the same trowel over and over. In effect, trowel teeth are worn down which translates to improper coverage.
