Things To Know About Brick Pointing

Old Bricks Repairing

First, rake out the old mortar to re-point damaged joints and then insert a new mix. Usually, it consists of one part of cement, one part of hydrated powder lime, and six parts of soft sand. The lime renders the combination much more workable, but with a few drops of a patented liquid plasticizer, you can swap it. The mortar is likely to shrink and crack when it dries as you render the blend thicker by increasing the proportion of cement. Also, when wet, it will impede the drying of the wall.

If you are just re-pointing a few bricks, then you can acquire mortar mix bags that you simply add water to. Tip out the entire content and thoroughly mix it together, then put what you don’t want back into the bag. The ingredients tend to separate and you can avoid using too much or too little cement if you just tip out what you will need.

Preserving Bricks

If some bricks are spoiled, then the rest may be porous and will require protection. For a paintbrush or roller, the simplest way will be to add a water-repellent seal.

Patching up damaged or spoiled bricks with mortar, colour-matched to the adjacent ones, is one solution. This, though, is hard to do properly. And water may be drawn in by capillary motion if you have any flaws or openings between the patching mortar and the wall as well, creating more complications.
