STEP ONE: MIX THE MORTAR

 

 

Mix a small amount of filler, using one part Portland cement, one part hydrated lime and six parts sand. Mix the dry materials and add water slowly, forming a thin, pourable grout. Add mortar colouring, testing the mixture on a scrap of corrugated cardboard to match the colour of the old mortar. Next, mix a bucketful of grout in the same proportions.

 

Getting the mortar is right is vital. If you’re struggling to achieve a mortar mix that matches your wall, our professionals are willing to help. The team at SA & SJ Brick Restoration possess the skills and knowledge required to create a mix of mortar that is safe for your bricks, and is suitable for the type of crack.

STEP TWO: PREPARE THE CRACK

 

 

Wearing safety goggles, chisel out, wire-brush and flush the crack with water to clean it thoroughly. Scrape out the crack, ensuring that it’s clean from dirt and debris. Use a garden hose to flush it with water.

 

Working quickly, spray the inside of the crack lightly to dampen it. Mask the lower third of the crack with duct tape set over the opening, and set a wide board flat against the wall to hold the tape in place, wedging it firmly upright with a 2 x 4 prop.

STEP THREE: FILL THE CRACK

 

 

Filling a wide and deep crack is more complicated than a normal crack – which is walked through here http://brickrestoration.company/repairing-cracks-in-wall.html. More equipment is required, more steps are taken and a helper is needed. To begin with, you must use a wide-mouthed funnel and a length of rubber tubing to fill the crack. Next, push one end of the tubing over the narrow end of the funnel and set the open end into the crack. Hold the end of the tubing at least halfway into the crack and as near the bottom as you’re able to reach over the board wedged against the wall.

 

Pour the grout that was made into the funnel, filling the bottom of the crack. Finally, remove the tubing from the crack. Ensure to rinse the funnel, tubing and the bucket thoroughly. Let the partially filled crack set for about one day.

STEP FOUR: FINISH AND REPEAT

 

Having removed the board and the duct tape from the crack, use a mortar jointer – or thin metal rod that has been curved as a mortar jointer is – and a trowel to finish the crack, matching both joint and brick textures.

 

Spray inside the crack lightly with a hose and repeat step three. Mask the crack with duct tape and wedge the board back into place against the wall. Using the wide mouthed-funnel, pour the grout into the crack as before, leaving it to dry for a day. After it’s dried, again finish the grout with a mortar jointer to match the joints and brick.

 

Repeat the filing and finishing process daily, section by section, until the entire crack has been filled. Ensure that the colour and the mix of the grout is made in equal proportions each time, and spray the patched area lightly with a garden hose several times a day during the curing period.

How to repair bigger cracks

Does the crack in your wall seem bigger every time you look at it? It probably is. The longer a crack in your bricks is left, the wider the gap will become.
