![]() ![]() Mortar Differences Between Repointing and Tuckpointing This often makes tuckpointing a better choice for outside corners because it can be easier and faster to do. Repointing outside corners may also require additional materials and labour because so much more original mortar must be removed in order to create the right angle for the new mortar. This can save money since it doesn’t require as much material to achieve good results, but it will take longer than repointing if fast construction schedules are needed. Tuckpointed joints also require less time than repointed joints because no mortar bed needs to be built up before tuckpointing is done. Tuckpointing is more suited for small, inconspicuous areas that would be difficult or impossible to repoint because they are too high or too low on the wall surface to allow enough working room with a trowel. This means that the exterior surface of a masonry wall will probably look cleaner after it has been repointed rather than tuckpointed, but this does not mean tuckpointing is necessarily a bad way of doing masonry restoration. Also, repointing allows the original stone surface to be cleaned before new mortar is added, whereas tuckpointed joints need only be brushed clean after they have cured completely. Repointing will generally provide more strength than tuckpointing because a large percentage of degraded mortar is replaced. If you’re only considering tuckpointing, you need to consider the age of your home or building, and the quality of mortar, to ensure that the best possible restoration results are achieved. However, tuckpointing may not yield as much long term improvement because there is so much less mortar being replaced. This means there is less time spent on restoration with tuckpointing than with repointing because so much more material will need to be removed for complete repointing. Tuckpointing may require less removal of deteriorated areas than repointing because tools are used which do not remove as much of the original mortar. Repointing should be used whenever deteriorated masonry needs to be stabilised without actually removing much of its original material. ![]() A knowledgeable person can usually determine just by looking at a stone building whether or not it has had one of these types of masonry restoration work done on it recently. When done properly, either method can strengthen old masonry walls while preserving their original appearance. In both cases, sand must be added to standard masonry cement to produce the desired colour match, and the new mortar must be allowed to cure before any water is allowed to penetrate it.īoth repointing and tuckpointing are generally considered standard conservation practices, but each has its own advantages. The tools and techniques for repointing and tuckpointing are similar.Both require that any deteriorated mortar be removed carefully with a grinder, wire brush, chisel or other tool before new mortar is applied with a small hand trowel. This coloured mortar will closely mirror the brick colour, and therefore the mortar line between the bricks will appear very fine. It refers to a final layer of coloured mortar being applied to the top of a repoint. Tuckpointing is an extra step in the restoration process. Although some minor deviations may be allowed for corners where masonry joints have shifted slightly, too great a difference can create an obvious visible mismatch. The new mortar applied during repointing must closely match the original composition and colour of the old mortar in order to blend in with it. Repointing is usually done around openings in a stone building to prevent water penetration at these weakened areas. Repointing is defined more specifically as rebuilding or replacing mortar which has deteriorated from age, weather, or other causes. ![]()
