The terms #pointing, #repointing and #tuck #pointing are often - TopicsExpress



          

The terms #pointing, #repointing and #tuck #pointing are often used interchangeably, which can lead to confusion for the average person or non-mason. The meaning of tuck pointing in one area of the country may be slightly different from that in another area, leading to conflicts regarding job specifications and expected repairs. Consequently, the following definitions of these terms were developed. * 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. * Tuck point - 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. Why Repoint? A common maintenance task for brick masonry is repair of mortar joints. 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. The longevity of #brick, however, may well exceed 100 years. Consequently, occasional repair of the mortar joints is expected over the life of the brick masonry. It is our observation that the most common reason for #repointing #brick masonry is to improve water penetration resistance. #Repointing #deteriorated #mortar #joints is one of the most effective and permanent ways of decreasing water entry into #brickwork. This is because the most common means of water entry into a brick masonry wall is through cracked or deteriorated mortar joints.
