Applications

HydroFort™ VB can be applied by brush or roller. A 270mm microfibre 5mm NAP roller cover is recommended. First coat should be thinned with water 10%, with the second coat applied undiluted to achieve an overall dry film thickness of 80 to 90microns.

Surfaces

All surfaces to be coated must be sound and free from dirt, grease, oil, or other surface contaminants. Holes, nonstructural cracks must be filled using a two component epoxy filler or equivalent. HydroFort™ VB can be applied to a damp but not saturated substrate or where there is freestanding water. When the product is to be applied to dry concrete it is advisable to wet the surface with a fine mist of water before application and allow to just surface dry.
