In order to obtain perfect finishes, it turns out to be necessary to join a facade according to the materials which compose it, for a result without apparent defect. In fact, the joints not only embellish an exterior wall and give a pleasant appearance, but they are also essential in terms of insulation in order to avoid excessive energy expenditure.

Preparation before joining

Depending on the nature of the exterior facade (stone, brick, final plastering, etc.), to join a wall, you will need the necessary tools. The visible joints tend to deteriorate over the years: they should therefore be changed if necessary so that they continue to play their protective and insulating role. For this, a cat tongue trowel is essential and you will need to dig to a depth of 1 to 3 cm or up to 1.5 times the width of the joints, paying attention to the masonry. A grinding wheel fitted with a grinding disc or a small chisel is generally sufficient for grinding and chiselling of facade joints.

A clean facade before the works

Once the old joints have been removed or for the installation of new joints, generally made of cement, a mortar should be applied which acts as a binder to seal the wall. Beforehand take care to clean your walls and facades between the interstices with a wire brush, so that the surface remains clean and that no residue remains. This is an opportunity to take a closer look at your masonry, to check that the blocks of stones or bricks are stable, and that they are properly sealed. If necessary, you can replace these using a sealing mortar, so that the entire masonry retains its original strength. It is preferable to prepare the mortar the day before with 5 volumes of water for 3 volumes of lime, then cover the mixture with a damp cloth.

Optimal finishes

Several mortar colors are available, and once the mixture has been prepared according to the manufacturer's instructions, the preparation, which must be homogeneous, has a duration of use of approximately 1h30. Then fill your joints with a trowel by applying the mortar in the interstices with a jointing iron, vertically then horizontally. Once this is done, allow it to dry for about 15 minutes and remove the excess mortar with a trowel. Whether your facade is made of stone or brick, you should brush the walls for optimal finishes without residue. To protect your facade from infiltration and to benefit from adequate insulation, waterproof your facade to prevent possible penetration of water.
