Parex Reproface

Stone and Brickwork Repair System

Parex® Reproface provides an effective lasting repair to natural stone and brickwork damaged by erosion or accident. It is a versatile  cementitious mortar that is through coloured, quick setting and can be moulded and textured to blend with the existing surface.

Parex® Reproface is available in 3 main colours – red, white and yellow and a range of shades to complement the natural stone and brickwork colours most prominent within the UK.  Where subtle variations in the colour and texture are required, a pigment based solution can be brushed into the surface to provide additional colour to emulate natural variations.

Usage

Typical repairs are to features such as: Cills, Headers, Mullions, Arches, Balustrades and other Mouldings. Parex® Reproface is a dry packed blend of Portland Cement, selected silica sands and chemical additives to provide excellent water resistance, thixotropy and workability. Excellent adhesion enables layers to be easily built up ready for finishing by marking to replicate the joints of the surrounding masonry or  textured using a variety of finishing methods to match existing.

Application steps

SUBSTRATE PREPARATION

  • Cut back the existing masonry surface to remove all loose and defective material to a minimum depth of 15 mm. The mortar bed should be included in this process.
  • Plugged stainless steel screws can be inserted into the existing masonry to assist the strength of the protruding repairs i.e. corners, corbelled brickwork etc.

MIXING

  • Parex® Reproface powder should be added to clean water whilst mixing is in progress.
  • Water demand is between 5 - 5.5 litres per 25 kg of powder depending upon the consistency required for installation.

APPLICATION

  • Wet out the area to be repaired, but avoid standing water.
  • Brush on a slurry coat of Parex® Reproface ensuring that all surfaces are covered. Whilst still tacky, force in repair mortar to cover the area being repaired, including the mortar joint.
  • When stiffening occurs, scratch the surface and add a second layer, if required.
  • After the Parex® Reproface stiffens, cut the perimeter back to form a new joint
