Instructions for Use

Joint Preparation

In order to ensure adequate bonding of the new mortar to the masonry, it is important that the old mortar is removed and that any residual dust is removed from the joint. Cut out defective mortar to a minimum depth of 8mm or 1.5 times joint width. Flush out with compressed air or water and leave surface damp.

Mixing

Place 3.75 L or 15 % of clean water in a mixing tub and gradually add dry Parex Historic Mortar AL-X whilst mixing (the quantity of water will vary with the colour used). Mix using a low speed/paddle mixer with clean water to produce a mortar with a consistency of finishing plaster. Allow to stand for 5 minutes and remix. To check consistency, fill the pointing gun to within 12 mm of the top and shake. Check correct consistency by filling the tube, the mortar should hang from the end of the nozzle when the tube is shaken. 

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 semi-dry surface skin and lost its initial sheen. The time this takes depends upon the absorbency of the masonry. Place the nozzle the face of the joint and inject the mortar filling the perpendiculars first and starting from the bottom of each joint. Finish the horizontal joints after 1-2 metres have been completed to the required profile. Parex® Historic Mortar AL-X may be placed at temperatures between +5 °C and +35 °C. Do not carry out jointing work if rain is expected.
