Broadcast Flooring

Scope of work for broadcast flooring
The specified system of broadcast flooring shall provide a wearing surface with waterproofing properties.
The system is based on a solvent free epoxy, which has a good resistance to wear and chemicals.
Advantages of broadcast epoxy flooring
Good impact resistance
Skid-resistant finish
Good chemical resistance
Suitable for wet process area
High wear and abrasion resistance
System build-up for broadcast system
1.If needed, moisture barrier (if > 4% pbw moisture content into the substrate)
Epocem Primer ( Primer coat) 1 x Epocem Primer Approximately 0.15 Kg/m²
Moisture barrier (Body coat) 1 x Sikafloor 81 Epocem (2 mm minimum): 2.1 kg/m²/mm
2. Primer + levelling broadcast course
Wearing course 1 mm (Levelling layer) Sikafloor 161+ Silica Flour :Approx. 1,2 Kg/m²/mm + 0.3 Kg/m²/mm
Broadcast onto fresh resin (Broadcast) Quartz sand from 0.3 – 0.8 mm or 0.6 – 1.2 mm 4 – 5 kg/m²
Sealing coat (Coloured coat) Sikafloor 264 0.7 kg/m² (minimum)
(Approx. system thickness from 3 mm, without moisture barrier)
Application of broadcast epoxy flooring system
Primer and leveling broadcasted course: Apply Sikafloor 161 and Silica Flour on a 1 mm thickness.
Broadcast the surface of the resin to excess to achieve the desired degree of slip resistance. Next day remove all excess by brush and vacuum.
Sealing coat: Apply a sealing coat of Sikafloor264 by roller or squeegee.
[NB. Certain colors may require a slightly increased consumption applied in two coats].
