Progrout Raking Out:

When repointing existing brick / stone work, old mortar should be taken out to a suitable depth, usually twice the width of the mortar joint. Using a hammer and chisel can be a slow job and result in damage to the face brick/stone work.

Progrout offers these solutions:

Diamond Raking discs in sizes 115mm and 125mm dia. Used on an Angle grinder the discs offer a most efficient method of removing all types of mortars - even hard ones.

Tungsten Carbide and Diamond Rakers. Used with a Sole Plate fixed to an Angle grinder. The Sole plate offers you the capability to attach to a vacuum to reduce dust and can also determine the depth of cutting by a simple adjustment.

Hosing the brick/ stone work with water before and after raking can substantially reduce dust and removes debris to provide a good key for the new mix.

Pointing with Progrout:

Progrout offers you the capability to repoint large areas in less time. On average using a Progrout can increase productivity by 300%.

To assemble your machine; attach the bottom bracket, the bar being cut to length to suit the drill of your choice, slot the Auger into position in the hopper and attach your drill.

Select the nozzle size required and screw onto the end of the hopper ensuring the rubber O ring is in place - tighten to prevent leakage and you can begin.

Key points to remember:

All mortars should be free of stones and lumps - It is important to sieve the materials with the sieve provided.

Use only 'fresh' cement and lime.

Do not use Play Pit sand or Kiln Dried - a good Builders Sand is perfect.

The consistency you require to use Progrout effectively needs to be wet but not watery. Many different mixes can be used as long as the mix has enough fattiness to enable it to be pumped.

A common mix is: 6 Parts sand; 1Part Lime and 1Part Cement

The mortar in any work should be sacrificial to the bricks or stone- the latter being more costly to replace. On older properties where soft bricks have been used a lime mortar is preferable since it will be forgiving where movement is occurring and will allow the bricks to breath and so save the face from being destroyed by frost.
