Epoxy resin flooring mortar for detailing work.
Sikafloor® 280 is a three component, solvent free, epoxy resin flooring mortar, particularly suited to detailing work.
Suitable areas of application:
The cementitious substrate should be sound and of sufficient compressive strength (minimum 25 N/ mm²) and pull off strength (minimum 1.5 N/mm²). The surfaces must be dry and free of all contaminants, e.g. oils, grease, surface treatments and coatings, etc. The substrate must be prepared mechanically to achieve an open textured fine gripping surface, free of cement laitance. Weak concrete should be removed and surface defects such as blowholes and voids must be fully exposed. All dust, loose and friable material must be completely removed, preferably by brush and vacuum, from all surfaces before application of the coating. Repairs to cementitious substrates and filling of blowholes, levelling of irregularities, etc. should be carried out using an appropriate product from the SikaDur®, Sikafloor® or SikaGard® range of materials. Prior to application, confirm substrate moisture content and RH. If >4% by weight and >75% RH, Sikafloor® EpoCem® may be applied as a DPM system.
Surface finish/ treatment
Standard product features
Compact to the appropriate thickness then trowel to a smooth finish. For thicker sections bulking of the product is achieved using clean, dry pea gravel (3–6 mm size) to create an ‘epoxy concrete’ typically used on sections 15–70 mm thick.
4 to 10 mm recommended.
Other colours to order; minimum quantity applies.
