Paint, laitance, and other poorly adhering contents must be mechanically removed. • Substrate must have an open textured surface to allow Sika® MB to penetrate. (Le. Blast cleaning, grinding are considered acceptable means to achevie the desired surface profile. Acid and chemical etching are not acceptable). • At least 50 % of the surface area must be cleared of residual adhesive and cutbacks. (i.e. by grinding or mechanical 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 "recommended 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 Sikae 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 determine 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 similar 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 consolidation / adhesion promotor, prepare the Product Oata Sheet Sika- MB June 2019, Ver5nn 01.04 020512081000000017 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 accordance with the open time'. 2 coats application: Apply the first coat at 75-115 ftz/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 Sikae Level-02 EZ Primer in accordance with the application time window'. When the primer is dry, apply Sika' Level products. 'ref. to applicticn time in sections above CLEANING OF TOOLS • Clean all tools and application equipment with cleaning solvent (Xylene, MEK are effective). • Hardened/cured material can only be removed mechanically. LIMITATIONS • Proper coverage must be used to achieve moisture barrier 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 Possible curing and adhesion problems. • Sika' recommends the use of Sika' Level products on top of it. • Floor covering manufacturer's and Wood flooring manufacturer'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 maximum 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 adhesion problems. For detailed instruction contact our Technical Service. When used in conjunction with SikaBond•, Sikae MB does not need to be broadcasted with sand. 3/4 BUILDING TRUST BASIS OF PRODUCT DATA LEGAL DISCLAIMER Results may differ based upon statistical variations depending upon mixing methods and equipment, temperature, application methods, test methods, actual site conditions and curing conditions.
