Application

Preparation of the substrate
Remove all concrete which has deteriorated or is at risk of detachment, until a solid, strong rough substrate is obtained. Remove all loose parts with a hydro jack-hammer. All previous repair work which is not perfectly bonded must be removed. Eliminate all old paintwork, oil, dust and any other material which may impede the bonding of Mapegrout SV T to the substrate.  Saturate the substrate with water. Before applying the product, wait until all excess water has evaporated. If necessary, use compressed air.

Preparing the mortar
Pour 12.5-13.5% of water into a cement mixer (3.1-3.4 litres per 25 kg bag). Slowly add Mapegrout SV T and mix for 1-2 minutes. Remove all the powder which has not blended with the mix from the sides of the mixer and continue mixing for 2-3 minutes, until a smooth, homogenous blend is obtained.

Laying the mortar
Apply Mapegrout SV T using a trowel in the pre-prepared area. Compact the mortar to get rid of any voids, either manually with a trowel or with a vibrator with a pronged fitting. Smooth off the surface immediately with a finishing trowel. If required, after fixing drain covers or man-hole covers in place, lay fresh asphalt around the area. We recommend applying a layer of at least 3 cm thick in order to bond well and to bear the weight of traffic without cracking.
