MS Flex Adhesive 15kg 

MS FLEX MAXI is a single-component hydro-curing prepolymer based adhesive with a silanic termination (MS technology) designed for use with timber flooring.  
Recommended for gluing of pre-finished wooden floor onto marble, grit, ceramic or marble-chip floor tiles, etc. Also suitable for gluing wooden floor onto underfloor heating and cooling system. MS FLEX MAXI has very good acoustic insulation characteristics. CERTIFICATES: EC1 PLUS, Ü-Mark of Conformity, heat conductivity (CSI test report n° 0013/DC/TTS/19). MS FLEX MAXI can contribute to the achievement of QI CREDIT 4.1 according to the parameters of the GEV dated 03 March 2009, because it meets the certification LEED protocol (Leadership in Energy and Environmental Design).

Apply MS FLEX MAXI paying attention to lay the wood blocks side by side and knock them down well to make sure the adhesive glues well to the entire surface. Perfect adhesion to the subfloor is ensured if at least 65% of each wooden component is in direct contact with the adhesive. 
Subfloor with radiant floor heating, apply one coat of PRYMER SF 1105 (see technical data sheet) and after 24 hours proceed with the application of MS FLEX MAXI. 
If the subfloor is porous or friable, we suggest to apply a coat of PRIMERFAST. The drying time for the subsequent coats depends on the primer used (see technical data sheets). 
If you need to glue the wooden floor onto glazed subfloors (such as ceramic, enamelled tiles or polished marble, etc.) remove and clean the surface from dust, grit, glue and waxes. Apply by cloth the adhesion promoter LEVIGATORE LIQUIDO following the correct application time (see technical data sheet), then apply MS FLEX MAXI. 
Sand the surface of anhydrite subfloors thoroughly using 24 or 36 grit sandpaper; remove dust and apply primer using PRYMER SF 1105 (do not dilute) or PRIMERFAST (diluted with 30% of DMC 50). Even PRYMER PUB 77 can be applied on the anhydrite subfloors with DILUENTE DMC 50 in a 70:30 ratio. 
MS FLEX MAXI must be acclimatized at room temperature before being applied. Sand the floor after 3-4 days, depending on the atmospheric conditions and humidity level of the wood species used. The possible excess of glue can be removed with a humid cleaning cloth. In case of left over, seal the bucket properly by using both lids to avoid waste.
