灰浆到时间就酥脆了，漏水。塑料或者金属siding不用维护，而且50年一换。 |

再用。买少量新砖就可以。

Repointing process
Sound mortar normally does not need to be removed from a building during the
repointing process, although such a practice is common. New mortar can be
designed to match the color and texture of existing mortar to avoid visual
aberrations. The repointing process begins by removing damaged pointing to a
depth equal to or slightly more than the width of the joint, or to the
point where sound mortar is reached. Depths greater than 2-1/2" or 4 cm
would be filled in several passes, allowing the mortar to cure for at least
24 hours. The joint profile would be as rectangular as possible as the new
pointing mortar should be allowed ample opportunity to bond with the masonry
unit.
Removal of old mortar between joints is done carefully to avoid damage to
masonry units. On very old buildings with soft materials, such as under-
fired brick, removal by hand is often the most effective to avoid damage.
Hard Portland cement mortar is usually removed with a grinder or power
circular masonry blade, taking care not to damage the masonry units.
Vertical joints in most cases are always done by hand or with small power
chisels.
Poor repointing work often raises the level of the mortar joint above the
face of the masonry unit, which causes the mortar edge to feather. Such a
process is aesthetically undesirable and can cause performance problems as a
thin layer of mortar will quickly erode. In addition, depending on the
nature of the mortar, mortar that rises above the level of the face of the
masonry unit can participate in damaging the arris or corner of the masonry
unit. In these cases, deteriorated mortar is often not removed to a
sufficient depth.

现在快40年，砖墙什么维护都没有做过。可是看上去情况很好。
老头没必要在这上面撒谎吧。

发帖数: 7156 | 14 如果是维护良好的 brick siding,只需从新勾缝就可以了。砖的寿命，理论上是100年
，但是砌砖的砂浆，寿命短的多。检修墙面往往会发现局部渗漏的情况（观察外墙表面
就可看见），这个时候，需要局部拆砖，甚至需要把整面墙的砖拆了，修复里面的防水
层，木板层。
