The most common repairs to brick and block walls, chimneys and brick veneer are cracks caused by wall movement or foundation settling and the deterioration of the mortar joint from exposure to the element over time. Once a crack develops it is important to seal the crack from water to prevent further deterioration.
Accordingly, is sealing brick a good idea?
Although brick is tough and durable, water can wreak havoc on this age-old building material. ... Apply a sealer to your exterior brick for protection against water damage and minimize moss growth. Clean the brick and allow it to dry completely. Apply a top-quality sealer using a pump sprayer and a paint roller.
In addition to, how long does Thompson's Water Seal last on brick? 10 years
In all cases, how do you seal brick mortar?
Scoop a dollop of mortar onto a brick trowel or hawk, hold it up even with a bed joint, and push the mortar against the back of the joint with the tuck-pointing trowel. Eliminate voids with a few slicing passes of the trowel's edge, then add more mortar until the joint is filled.

Warm water alone is typically sufficient in cleaning exposed brick but if the wall is particularly dirty, then the dish detergent and table salt mixture can cut through grease and stains. Apply it to the brick and let it sit for about 10 minutes before using the brush to scrub away the dirt.
However, most pressure-treated wood should have periodic sealing against moisture, preferably every year or so. ... The directions for some, such as Thompson's Water Seal, specify pressure-treated wood as a suitable use.
Using a small, sharp trowel, fill the cleaned-out joints with mortar, working first on the verticals and then on the horizontals. Pack the mortar in tightly, making sure there are no gaps or air holes. Finish each joint as you fill it; don't fill all the joints first and then go back.
Yes, mortar is waterproof. It is "relatively unaffected" by water "under specified conditions". However, anything claiming waterproof is likely a long way away from being watertight or impervious to water. M4 mortar is actually just concrete, with one part portland and four parts sand, according to Boral.
Cracking of Lime Mortar has several possible causes: Lack of moisture control – Drying and carbonation are two different processes, just because a mortar is dry it does not follow that it has carbonated. ... If pointing dries before sufficient carbonation has taken place then cracking can occur.
Mix in powdered latex bonding agent, an additive commonly used to turn any type of mortar into a stickier, flexible finished product. The latex additive functions exactly like the premixed latex mortar, but you can vary its stickiness factor by changing the amount of latex you add to the mortar.
