Using Ronascreed Mortar – High strength floor screed and repair mortar

Preparation

The substrate to which RonaScreed Mortar is to be bonded must be structurally sound and stable. Minimum compressive strength should be 25N/mm2 and minimum pull-off strength should be 1.5N/mm2. Surfaces should be vacuum shot blasted, planed or scabbled to expose aggregate, remove laitance and provide a mechanical key. All grease and oil must be removed. Dust, debris and loose material must be removed by vacuuming. Any defect or weakness in the substrate may result in failure of the topping or screed applied to it. The recommendations given in BS8204-3 section 7 should be followed, to assess the suitability of the substrate and ensure the performance of the topping. When repairing concrete with RonaScreed Mortar, repair perimeters must be saw cut and the concrete scabbled as required, to allow the minimum depth of mortar to be placed throughout.

Wetting

The prepared surfaces must be thoroughly wetted with clean water. Very porous surfaces may require soaking for up to 24 hours. All surplus water must be removed before the primer is applied.

Priming

Brush apply a coat of Ronacrete Rapid Primer to the damp surface immediately before applying RonaScreed Mortar. Mix the primer thoroughly and apply evenly
over the surfaces ensuring total and uniform coverage taking care to avoid ponding. Only prime an area of floor which can be covered by the mortar within the working time of the primer. The coverage rate of Ronacrete Rapid Primer is 1.5-2m² per kg. Note that the primer must not be allowed to dry. Dry primer must be thoroughly abraded and reapplied.

Mixing

RonaScreed Mortar must be mixed by forced action mixer (e.g. CreteAngle, Baron or similar) or high powered, slow speed drill and suitable spiral paddle (MR4 or similar) for approximately 3 minutes, shorter mixing times will not fully disperse the components and workability will be reduced. (continued) Free fall mixers must not be used. Once mixed the mortar should be used as quickly as possible.
