TRFS Polyurethane SL is a three-component polyurethane flow -applied flexible floor topping with a semi-gloss finish.
Applications
TRFS Polyurethane SL is suitable for the protection of concrete floors subject to medium duty traffic (regular foot traffic, occasional fork lift truck traffic, occasional hard plastic- wheeled trolleys). TRFS Polyurethane SL can be applied to concrete, polymer modified sand/cement screeds, steel, timber and some asphaltic surfaces.
Features & Benefits
• Low odour
• Hardwearing, tough and resilient
• Seamless
• Hygienic / easy to clean and maintain Thickness 2.5 - 4 mm Temperature Resistance TRFS Polyurethane SL is resistant to occasional spillages up to 40°C. Typical Properties, 7 days at 23 oC
Coverage*
2.5 mm @ 4.5 kg/m2 4mm@7.4kg/m2 * Coverage figures given are theoretical. Practical coverage rates may vary due to wastage factors and the type, condition, profile and porosity of the substrate.
| All surface contamination, e.g. oil, paint and rubber, should be removed by mechanical means to expose the coarse aggregate. After surface preparation, all loose debris and dirt should be removed by vacuum equipment. A close visual examination should be made to verify cleanliness and soundness. Any weak or suspect areas should be repaired. | |
|---|---|
| Heavy oil or grease deposits should first be removed either mechanically, by steam cleaning, or by biological treatment, then by high pressure water blasting followed by the application of TRFS Damp Tolerant Primer. (see separate data sheet). | |
| Where oil or grease contamination has been severe or of long duration, none of these methods may prove satisfactory and in these cases removal of the affected base would be necessary. In existing buildings without a functioning DPM, the application TRFS Damp Tolerant of should be considered. | |
| Hydrostatic pressure may, under certain circumstances, cause adhesive failure between the flooring and the substrate. Where this is likely to occur, such as in areas where the ground water table is higher than the substrate, and where external tanking has not been applied, pressure relief must be provided e.g. by direct drainage. | |
| Priming Substrate relative humidity <75% | TRFS Standard Primer Substrate relative humidity >75% |
| If, when cured, there are dry patches, a further primer coat is required. Allow to cure for a minimum 12 hours at 20 oC. If the primer has been left to cure for >48 hours then the primer surface should be mechanically abraded and the area re-primed. Failure to do so may result in pin-holing of the surface topping. | |
