The high quality of joints depends on the respect of the conditions of use and on the good care of the tool, which are far from demanding.

• Before connecting the machine and after having fixed one of the nozzles according to the width of the joint, you must wet the inner surface of the tank. That will prevent the mortar from sticking to the sides during the work.

• The choice of the appropriate mortar is essential. The mixing must be creamy and the granulation must be 0.2 mm (for the ground) or less (ideal for the homogeneity of the joint). «LP Joint» by Laporte which is ready to use and available in 4 different shades is perfectly suited.
  • For walls the granulation must be between 0,4 to 0,6 mm (Laporte recommends the Pierra products).

• The pointing is made sector by sector, beginning with all parallel joints. Place the nozzle in the joint, turn the regulator of flow on and pull the machine regularly and continuously, reducing the flow of mortar at intersections if necessary. Perpendicular joints are subsequently filled. At the intersections of tiles you simply reduce or stop the flow of mortar, depending on your first passage.

• When the tank is empty, or if you interrupt your work for a few minutes and before reloading it with mortar, make sure that you have cleaned the tank as well as the nozzle. Once the pointing machine is unplugged, you must first take out the pushing rod, which is linked to the motor block. The motor block is taken off and cleaned with a damp sponge only. The tank and nozzle can be washed with a water jet or by immersing. Make sure that no marks of mortar remain.
