Plesons Brick and Stoneworks Signature Tuckpointing Procedure

Step 1-Evaluate the mortar, 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 are often used.  Mortar type is also a big factor in

         tuckpointing.  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

         tuckpointing 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, we use the

         prosoco brand.  Prosoco carries a wide variety of masonry detergents, acids, restoration

         cleaners, mold killer, effloresance 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 contactor 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.

Tuckpointing Definitions & Brief Information

      Tuckpointing can be defined as the removal and replacement of old crumbled mortar

between bricks and stones. Tuckpointing is also known as repointing 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:

Point - to place plastic mortar into joints to correct defects or to completely fill joints in newly

laid masonry.

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. (2) see repoint.

Why Tuckpointing?

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 tuckpointing 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 selected 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.

Brick Replacement and Plugging Procedures on Existing Buildings

  Spawled or cracked brick can severely detract from the visual as well as the structural

integrity of your building or home!
 
   Brick replacement is an art by itself when considering replacing damaged brick in a wall,

ornamental borders, tight joint home fronts and other decorative masonry.  It takes a keen

sensed mason to perform these tasks and end up with satisfactory job.
   
   The end result is affected even more before one brick is even laid.  Unsatisfactory brick

matches are all too common in the St. Louis region, drive around the city and look at old

buildings and you will see what is being talked about here. 
   
   Matching brick on older homes and buildings can be a chore.  If the brick cannot be found at

a local brick yard and are no longer made, the only option is to find used brick that are a close

match to the original.  This can take many trips and phone calls to used brick dealers to find a

satisfactory match.  Taking the time to find these matches can make the difference between a

tolerable brick match or an exceptional brick match which we take great care and pride when

doing so.
