Tuck-pointing can be defined as the removal and replacement of old crumbled mortar between bricks and stones. Tuck-pointing is also known as re-pointing or just pointing. All three terms are often used interchangeably to describe the complete process of restoring older masonry joints. The following definitions of these terms have been recommended by The Brick Institute of America:
Repoint – to place plastic mortar into cut or raked joints to correct defective mortar joints in masonry.
Tuckpoint – to point masonry with a flush mortar joint that approximates the color of the masonry units and a mortar of contrasting color that is shaped into a thin strip.
The most common reason is to remove loose or cracked mortar from brickwork or stone installations. The longevity of mortar joints will vary with the exposure conditions and the mortar materials used, but a lifespan of more than 25 years is typical. Persistent damage from water, sun, acids in the rain, changing temperatures, building settlement, impact damage, and dirt take their toll. Damaged mortar joints become a waterproofing problem, and eventually a structural issue, if not repaired. When visual inspection reveals that the mortar joints are cracking or otherwise deteriorated, restoration is necessary to help maintain the integrity of wall systems and products.
Tuckpointing and repointing are two effective ways of ensuring structural integrity and decreasing water entry into masonry as well as old structures. Tuck-pointing can also be used for newer jobs where mortar may have been damaged or needs to be replaced because of different problems with color or finish. In these instances mortar for tuckpointing must be carefully done to ensure that the color and texture of the new mortar closely matches the existing material that was not compromised and did not need to be removed.
Steps for Tuckpointing
Step 1-Evaluate the old mortar removal process
Old mortar removal is accomplished by either grinding, chiseling or hand raking the deteriorated mortar from the joints to a minimum depth of 5/8”. Then the joints are either hand brushed or blown out to remove dust and debris to insure a strong bond with new mortar.
Step 2-Repointing procedure
Once the joints are cut out and properly cleaned, new mortar can be applied to the joint with a jointer. There are many different joint styles available. Concave, flat, weathered, raked and grapevine just to name a few that are often used.
Mortar type is also a big factor in Tuck-pointing. Historic homes often used softer brick than the units available today. These soft brick cannot tolerate the high compression strength of Portland rich mortars used in present masonry construction. This hard mortar commonly causes the soft brick to give way when settling, expansion and contraction, and other movements occur which result in spawled or sheared brick faces, severe cracking, and chipped brick edges. To avoid these problems a lower compression strength lime mortar must be used.
Color match Tuck-pointing is an art that is accomplished by highly experienced masons who can break down the mortar to find out what was originally used. Type of sand and tooling techniques play a dominant role in proper matching of mortar. This process can be a time consuming but rewarding task when the project is completed. Once the joints have been pointed and properly brushed the curing process begins.
Step 3-Cleaning process
Once the joints have cured it is time to determine if a cleaning procedure should be performed. There are endless masonry cleaning products and procedures. Upon inspection we will determine and discuss the options that will be best for the type of brick and mortar installed. We have a wide variety of masonry detergents, acids, restoration cleaners, mold killer, efflorescence removers and white scum removers to bring grungy looking building or homes back to their original beauty.
Step 4- Waterproofing
To get the best performance it is always recommended that a sealer is applied after tuck-pointing, replacing brick, replacing stone, new brick, new stone on parapet walls, chimneys, or any other masonry unit that is exposed to the elements. Not all sealers are created equal! Please do not be fooled into a low quality sealer sold at the home improvement stores, they simply do not last. If a contractor tries to apply something of this nature to your building, simply refuse these products. A breathable, silicon based sealer such as prosoco Siloxane PD is a high quality product that goes on clear so there are no shiny, discolored, or patchy looking areas after application. This product has been tested to last for up to 10 yrs. In even the harshest environments. This is a breathable sealer which means if water were to enter the wall through a hole or crack it can still escape.
