Product Data Sheet Sika® MB December 2018, Version 01.03 020512081000000017 2/4 BUILDING TRUST APPLICATION INSTRUCTIONS SUBSTRATE PREPARATION • Substrate must be clean, dry, sound and homogeneous, free from oils, grease, dust, and loose or friable particles. Paint, laitance, and other poorly adhering contents must be mechanically removed. • Substrate must have an open textured surface to allow Sika® MB to penetrate. (i.e. Blast cleaning, grinding are considered acceptable means to achevie the desired surface profile. Acid and chemical etching are not ac- ceptable). • At least 50 % of the surface area must be cleared of re- sidual adhesive and cutbacks. (i.e. by grinding or mech- anical substrate preparation) • Old cutback can contain asbestos which is dangerous for the health so do not grind, sand or blast. Refer to the Resilient Floor Covering Institute's publication "re- commended work practice for removal of resilient floor coverings" for instruction. • Minimum substrate compressive strength > 1,160 psi. Tensile Bond strength > 116 psi at the time Sika® MB is applied. • Repair with Sika Level SkimCoat or SikaQuick' mortar before priming. • The floor must be cleaned with an industrial vacuum prior to installation of the Sika® MB. • On fiber reinforced concrete, fibers should be flamed off the surface prior to application of Sika® MB as a moisture barrier. • Before overall installation begins, Sika® recommends the application of several small test patches to determ- ine primer application requirements and acceptability of final product performance. MIXING • Add one full can of component A to one full can of component B then mix with an electric drill and mixing (Jiffy Mixer type) paddle at a low speed to reduce air entrainment (300-400 rpm). Using a paint stick or sim- ilar is not sufficient to mix the primer. • A minimum mixing time of 3 minutes shall be observed; mixing shall continue until a homogeneous mix has been achieved. • Scrape sides of pail with paint stick or paddle to ensure all contents are thoroughly mixed together. • Unmixed material applied to the floor will not cure properly. APPLICATION METHOD / TOOLS • Apply Sika® MB uniformly (in 2 directions 90°) to the substrate using a medium nap roller, ensuring that a continuous coat is achieved over the entire surface (MUST produce a mirror like finish). • Pour contents of pail onto the floor for best working time. Attempting to work from the pail will reduce working time. • When used as a moisture barrier and substrate consol- Product Data sheet Sika' Me December 2018, Version 01.03 020512081000000017 3/4 idation / adhesion promotor, prepare the substrate mechanically as in accordance with the guidelines stated in subtitle "Surface Preparation". Apply the first coat at 10 mils Apply the second coat at 15 mils in ac- cordance with the open time*. 2 coats application: Apply the first coat at 75-115 ft2/gal Apply the second coat at 150-225 ft2/gal in accordance with the application time window*. Then follow one of the option: • Option 1: Broadcast to refusal with oven dried silica sand (20/30) on the second coat immediately. Sweep sand once the epoxy is cured. Apply Sika® Level products on cured epoxy. • Option 2: Apply Sika® Level -02 EZ Primer in accordance with the application time window*. When the primer is dry, apply Sika® Level products. -ref. to appliction time in sections above CLEANING OF TOOLS • Clean all tools and application equipment with clean- ing solvent (Xylene, MEK are effective). • Hardened/cured material can only be removed mech- anically. LIMITATIONS • Proper coverage must be used to achieve moisture bar- rier properties. • Will not act as a moisture barrier for gypsum screeds. Gypsum based subfloors are very susceptible to excess moisture and will be degraded if exposed to excess moisture from below or above. • Only protects from moisture coming from below the concrete. • Will not prevent hydrostatic pressure. • Must not be applied to a visibly wet substrate. • Does not prevent moisture occurring between the epoxy and the floating floor due to secondary sources of moisture or acclimation, e.g. water condensation. • Is not suitable for use with bonded systems due to pos- sible curing and adhesion problems. • Sika® recommends the use of Sika' Level products on top of it. • Floor covering manufacturer's and Wood flooring man- ufacturer's recommendations, like room humidity levels and wood acclimation requirements should be strictly followed. • Sika® does not make any standing recommendations as to the structural integrity of old adhesive residues or subflooring materials that are not manufactured by Sika'. • When left on the substrate for more than the maxim- um allowable open time of 36 hours, prior to placing the adhesive, the surface must be thoroughly cleaned and mechanically prepared (i.e. screened sand) and solvent wiped. Failure to do this, may result in adhe- sion problems. For detailed instruction contact our Technical Service. When used in conjunction with Sika - BUILDING TRUST Bond®, Sika® MB does not need to be broadcasted with sand.
