What is Monarcoat 500?
Monarcoat 500 is a flexible high build polyurethane floor coating with excellent abrasion and impact resistance and provides a medium duty coating for floors. Two coats of Monarcoat 500 provide a build equivalent to almost 10 coats of conventional solvent containing coatings. Monarcoat 500 can be applied as a one coat application at a coverage rate of 0.365g per m² or over (the aesthetics are dependent on application technique and substrate quality).
Fast curing at low temperature
Very low odour
Tough but flexible
Can be applied onto a wide range of substrates
Can be used in decorative and functional environments
- Where a high-build UV stable coloured top-coat/seal coat required
- Areas where fast turnaround but high-performance finishes are required
- Commercial and Industrial
- Decorative floors
Supplied in 5 kg and 10 kg units
Monarcoat 500 is suitable for the protection of concrete floors subject to medium duty traffic (regular foot traffic, frequent fork lift truck traffic, occasional hard plastic-wheeled trolleys). Monarcoat 500 can be applied to concrete, polymer modified cementitious screeds, steel, timber and asphalt. Typical uses include areas requiring good wear resistance combined with economical cost such as storage areas, plant rooms, warehousing, toilets etc.
Monarcoat 500 provides a medium gloss surface in a range of colours with a slightly stippled finish.
Excellent wear resistance can be expected from a two coat application.
0.25 – 1 mm depending on application rate and number of coats.
Inadequate preparation will lead to loss of adhesion and failure. In coatings, there is a tendency for the finish to mirror imperfections in the substrate. For concrete substrates, grinding or light vacuum contained shot-blasting is the preferred option.
Monarcoat 500 does not normally require a primer on dry substrates. When treating extremely porous or damp concrete, prime as follows:
Substrate relative humidity <75%: Monarprime
Substrate relative humidity >75%: Monarprime DPM
The ideal ambient, substrate and material temperature range is 15 – 25 ºC. Localised heating or cooling equipment may be required outside this range otherwise the surface finish and application viscosity may be impaired. The maximum substrate and atmospheric relative humidity should be 75%. The substrate and uncured floor must be kept at least 3 ºC above the dew point to reduce the risk of condensation or blooming on the surface, from before priming to at least 48 hours after application.
Prior to mixing, the temperature of both components must be between 15 and 25 oC.Add the hardener component to the coloured resin component and mix using a low speed electric mixer (300 – 400 rpm) for at least 3 minutes until homogeneous. Keep the mixing paddle fully submerged to avoid the entrapment of air and scrape the sides and bottom of the vessel several times. Decant the mixed material to a second mixing vessel and mix as above for a further minute. Apply with a medium roller directly from a paint tray. Push the resin well into the surface making sure the floor is fully wetted and then pull back lightly with the roller to the required thickness. For a 1 coat application we recommend that a rubber lipped squeegee is used followed by a short nap roller. This may produce a slight orange peel effect across the surface.
Store off the ground in un-opened packs in a dry store, under cover between 10 ºC and 30 ºC out of direct sunlight. Protect from frost
Coverage (nominal 0.5 mm thickness)*
1st coat approx. 0.500 kg/m²
2nd coat approx. 0.300 kg/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.
Monarcoat 500 is not colour fast and may yellow over time. This will be more pronounced with lighter colours and blue shades and does not compromise the product’s performance or chemical resistance characteristics.
Regular cleaning is essential to enhance and maintain the life expectancy and appearance of the floor. Monarcoat 500 can be easily cleaned using industry standard cleaning chemicals and techniques. Consult your cleaning chemical and equipment supplier for more information.
