Heavy Duty Polyurethane Hybrid Flooring System
Uramassetto M1 is a single layer, seamless, solvent free, polyurethane based flooring system. its textured matt finish possesses excellent chemical resistance, withstands abrasive wear; has high impact resistance and withstands direct steam contact and cleaning practices.
30 Kg kit
Design Criteria: Uramassetto M1 is designed to be a hard wearing trowel applied Polyurethane screed on cementitious or metal substrates at thicknesses 6, 9, or 12 mm. The applied product will be resistant to water as well as a wide range of chemicals.
ConsumptioN: 2.2 – 2.5 kg/m2. Stated consumptions data are for general guidance. Actual consumption depends on the nature of substrate, method of application and wasteage.
Original sealed bag of Uramassetto M1 has a shelf life of 12 months provided it is stored clear of ground in a dry and shaded place below 35ºC.

All surfaces receiving URAMASSETTO M1 should be primed with URAPRIME W which is designed for maximum absorption and adhesion to concrete substrates. Add the entire contents of the hardener tin to the base tin and mix the two primer components thoroughly for at least 2 minutes - only mix full packs.
Once mixed, the primer should be applied immediately to the prepared substrate using stiff brushes and/or rollers. The primer should be well ‘scrubbed’ into the substrate to ensure full coverage, but care should be taken to avoid over application or ‘ponding’.
Allow the primer to become tacky before proceeding to the next stage. Porous substrates may require a second primer coat - when the first coat is directly absorbed into the substrate - but minimum over-coating times must still be observed.
Uramassetto M1 is supplied in three pre-weighed packs (base, hardener and aggregate) which are ready for immediate on-site use. Part mixing of these components is not acceptable and will affect both performance and appearance of the finished floor.
Mixing should be carried out using either a forced action mixer; or a heavy duty mobile mixer fitted with a suitable jiffy type mixing paddle. All such equipment should be of a type and capacity approved by Colmef Monneli.
The components should be mixed in a suitably sized mixing vessel. Stir the base and hardener components individually then empty them into the mixing vessel scrapping the edges and mix for 2 minutes.The contents of the graded aggregate pack should be slowly added and mixing carried out for a further 3 minutes until a completely homogeneous material is obtained.
Should be spread to uniform thickness on the primed surface using either a screed box or the edge of a steel trowel. The material should be tamped with a wooden float to ensure complete compaction and finally finished to a closed even texture using a steel trowel.
Screeding rods are useful to maintain a minimum compacted thickness of 6 mm. The material must be applied within the pot life after mixing.
Uramassetto M1 can be used to form perimeter edge coving up to a height of 225 mm. Skilled applicators can also use it to repair stair treads and fix expansion joint edges.
Although Uramassetto M1 is impervious at 6 mm thick in constantly wet operations areas or where a high degree of cleanliness is required.
All tools and equipment shall be cleaned immediately after use with water.
The surface should be sound, clean, free from loose material, grease, laitence, dirt curing compound, etc.
Laitence and weak surface layer shall be removed using mechanical methods such as grinding or blasting in order to provide a sound well profiled surface. All necessary repairs should be made prior to application by using the same material. New concrete floors shall be at least 5 days old and visibly dry with no standing water on top.
Uramassetto M1 should not come into contact with skin and eyes or be swallowed.
Avoid inhalation of vapour and spray. Use only in well ventilated areas. In case of insufficient ventilation wear suitable respiratory protection.Wear suitable protective clothing, gloves and eye/face protection. Barrier creams provide additional skin protection.
Should accidental skin contact occur, remove immediately with a suitable skin cleanser followed by washing with soap and water. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
If swallowed, seek medical attention immediately - do not induce vomiting.
