Designed for gun-injection, Parex Historic Mortar provides a cement-free mortar for pointing soft brick or stonework. Consistent in both colour and finish, Parex Historic mortars are pumped deep into the joint, providing a complete fill and a degree of flexibility. The mortar is porous allowing the passage of water through the mortar joint.
- Can be injected into joints as narrow as 5mm and will penetrate to a depth in excess of 100mm, allowing for the deepest of joints

Features & Benefits
- Fast application
- Cost effective
- Cement free
- Complete joint fill
- Srain free & colour consistent
- Dry packed blend of lime complying with BS EN 459-1, GGBS complying with BS EN 15167, selected silica sands and natural aggregates complying with BS EN 13139 together with additives to provide water resistance, thixotropic properties, workability and colour
Joint Preparation
- In order to ensure adequate bonding of the new mortar to the masonry, it is important that the old mortar is removed, to a minimum depth of twice the joint width, and that any residual dust is removed from the joint
- If the masonry is porous, joints should be wetted down prior to repointing to prevent excessive suction
Mixing
- Place 4-4.5 litres of clean water in a mixing tub and gradually add dry Parex Historic Mortar whilst mixing (the quantity of water will vary with the colour used)
- Mix in a wide shallow pan using a low speed drill and Parex Historic Mortar Eproblender
- Mix until a consistency of stiff cream is achieved, adding a little extra water, if required
- Allow mortar to stand for approx 5 minutes
- Remix with the addition of a small amount of water, if necessary
- Check correct consistency by filling the tube, the mortar should hang from the end of the nozzle when the tube is shaken
- Each 25kg bag of Parex Historic Mortar will yield approx. 13.5 litres of mixed material
Placing
- Keeping the nozzle just clear of the wall, inject the mortar into the joint, slightly overfilling, working from the top of the wall downwards
- The mortar should be tooled off after it has formed a semidry surface skin and lost its initial sheen
- The time this takes depends upon the absorbency of the masonry
- Parex Historic Mortar may be placed at temperatures between 5°C and 35°C
- Do not carry out jointing work if rain is expected
