Where to Use ■ Moisture barrier to help control moisture propagation in cementitious substrates with a moisture content Cure Time not exceeding 6% by Tramex Method and residual moisture up to 100% R.H. or 25 lbs./1000 sq.ft./24 hrs. ■ For substrate consolidation on concrete, cement and gypsum screeds. ■ Adhesion promoter for old and new adhesive residues in conjunction with other Sikae products. ■ Sika® MB is suitable on concrete, cement, self -leveling and gypsum substrates, OSB, plywood, quarry and terrazzo tiles, water-soluble adhesive and cutbacks. Advantages ■ Solvent -free (100% solids) Shore D Hardness ■ Easy roller applied application, low viscosity Water Vapor Permeability ■ Convenient, easy to mix packaging (ASTM E-98) ■ Shorter construction periods VOC ■ Excellent penetration and stabilization of the substrate ■ Reduction of adhesive consumption ■ Suitable for use on floors with radiant heating Is Compatible with SikaBonde wood flooring adhesives, Sika® Level products. ■ Can be used below floating floors Coverage ■ 250 - 300 sq.ft. per 2.64 US. gal. pail when used as a moisture barrier ■ 400 - 450 sq.ft. per 2.64 US. gal. pail when used as an adhesion promoter or surface consolidator alone ■ MUST produce a monolithic, pinhole -free finish with a Continuous film. The need for multiple coats is directly related to surface absorption. (Coverage figures do not include allowance for surface profile and porosity or material waste). Packaging 2.64 US. gal. pails Typical Data (Materia/ and curing conditions @ 73°F (23°C) and 50% R.H.) RESULTS MAY DIFFER BASED UPON STATISTICAL VARIATIONS DEPENDING UPON MIXING METHODS AND EQUIPMENT, TEMPERATURE, APPLICATION METHODS, TEST METHODS, ACTUAL SITE CONDITIONS AND CURING CONDITIONS. Shelf life 2 years from date of production if stored properly in undamaged sealed containers Storage Conditions Store dry at 50°.F (10°C) to 77°F (25'C) Service Temperature -40°F to+158°F Color < Blue Chemistry Two component epoxy Density 69lbs/cu.ft. Cure Time ■ 50°F (10°C) 18 hours ■ 73°F(23°C)8houre ■ 86°F (30°C) 6 hours *Minimum curing time, prior to walking on primer/or for applying SlkaBond®or Sika® Level SdmCoat. Compressive Strength 10,000 psi (69 MPa) at 7 days Shore D Hardness '83 at 7 days (mixed A&B) Water Vapor Permeability 0.06 g/m' 24hour-mmHG (ASTM E-98) VOC <50 g/L (A+B combined) How to Use Surface Preparation ■ All substrates must be dry, stable, sound and free of all contaminants such as grease, oil, paint, wax, dust, curing and sealing compounds that will interfere with the penetration of Sika® MB. ■ All loose friable material, including preparation residue (i.e. Paint, laitance), must be completely removed using an industrial vacuum before application of the Sika® MB. The compressive strength of the concrete substrate should be at least 1,160 psi at 28 days with a minimum tensile strength of 116 psi at the time Sika® MB is applied. Repair with Sika® Level SkimCoat or SikaQuickO mortar before priming. ■ Substrate must have an open textured surface to allow Sika® MB to penetrate. Blast cleaning, grinding are Considered acceptable means to achieve the desired surface profile but acid and chemical etching are Onot acceptable. RRIOR TO EACH USE OF ANY SIKA PRODUCT, THE USLK MUS I ALWAYS READ AND FOLLOW THE WARN INA INSTRUCTIONS ON THE PRODUCT'S MOST CURRENT PRODUCT DATA SHEET, PRODUCT LABEL AND SAFETY DAT SI EET WHICH ARE AVAILABLE ONLINE AT HTTP://USA.SIKA.COW OR BY CALLING SIKA'S TECHNICAL SERVICE DE PARTMENT AT 800.933.7452 NOTHING CONTAINED IN ANY SIKA MATERIALS RELIEVES THE USER OF THE OBLIGATION 0 READ AND FOLLOW THE WARNINGS AND INSTRUCTIONS FOR EACH SIKA PRODUCT AS SET FORTH IN THE CUR RENT PRODUCT DATA SHEET. PRODUCT LABEL AND SAFETY DATA SHEET PRIOR TO PRODUCT USE. ■ 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. ■ 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. ■ Consult Sikes Corporation's Technical Service Department for recommendations. Mixing Add one full can of ComponentAto 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 ■ Apply Sika® MS 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). Application Recommended Coatings Results in Moisture barrier only Minimum lx Mirror like finish Substrate consolidation only Minimum 1x Good penetration Adhesion promotion only Minimum 1x Mirror like finish Moisture barrier+ substrate consolidation Minimum 2x Mirror like finish Moisture barrier+ adhesion promotion Minimum 2x Mirror like finish A waiting time of > 8 hours and < 36 hours must be observed between coats of Sika® MB ■ Pour contents of pail onto the floor for best working time. Attempting to work from the pail will reduce working time. Pot Life (Max. open time), If primer is left out of the pall after mixing: at +50°F (10°C) - 60 minutes at +68°F (20°C) - 30 minutes at +86°F (30°C) - 15 minutes ■ When used as a moisture barrier in cement substrates prior to applying Sikes Level products, 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 accordance with the open time (8 - 36 hrs.)'. If using Sika® Level products over Sika® MB, please see options below ■ Option 1: Broadcast to refusal with oven dried silica sand (20/30) on the 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 open time" window. When the primer is dry, apply Sika® Level underlayment products. 'When Sikes MB is left on the substrate for more than the maximum allowable open time at 36 hours prior to placing adhesive, the surface must be mechanically prepared (i.e. sanded) and solvent wiped before proceeding. Removal ■ 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. ■ Sika® MB 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. ■ Sikes MB only protects from moisture coming from below the concrete. ■ Sikes MB will not prevent damage to gypsum based subfloors that are exposed to excess moisture levels. ■ Sika® MB will not prevent hydrostatic pressure. ■ Sikes MB must not be applied to a visibly wet substrate. ■ Sika® MB does not prevent moisture occurring between the epoxy and the floating floordue to secondary sources of moisture or acclimation, e.g. water condensation. ■ Sikes MB is not suitable for use with bonded systems due to possible curing and adhesion problems. ■ Sikes 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. ■ Sikasdoes notmake anystanding recommendationsas tothe structural integrityofold adhesive residues or subflooring materials that are not manufactured by Sikas.

Failure to do this, may result in adhesion problems. For detailed instruction Contact our Technical Service. When used in conjunction with SikaBonde, Sikae MB does not need to be broadcasted with sand.
