Among the mortar repair products are books and videos for How to mix mortar, how to repoint mortar, how to repoint brick, brick repair mortar, and custom pre mixed mortar.
What is Masonry Repair?
Masonry repair is the process of restoring brick and mortar. This is often done by pointing mortar joints or repointing brick mortar to repair the cracks or deterioration of the mortar between the bricks or replace the bricks themselves.
During the process of mortar restoration, the damaged mortar or brick are removed and the mortar joints are cleaned to prepare the wall for repointing. Repointing of mortar is often called tuckpointing, tuck and point mortar repair, or generally tuck pointing.
After the area is clean and ready for tuck pointing mortar, the cement mortar or lime mortar for pointing is mixed and pointed into the joints between the brick with specialized masonry tools.
This makes masonry brick repair sound simple, but there is far more to restoring masonry than just repointing the mortar. The first step in mortar restoration is identifying the mortar type. Pending the mortar type, the mortar will have higher or lower compressive strength. If the compressive strength of mortar used for tuck pointing repair is harder than the cement in the wall, the new mortar will not bond to the old mortar and will cause damage to the masonry units and wall around the repair. Similar issues occur when the mortar compressive strength of the repair mortar are softer than the old mortar. Cement Mortar Analysis provides a detailed mortar formula and mortar mix ratio through testing of mortar samples.
What is Mortar Analysis?
Mortar analysis is the process of analyzing samples of old mortar to identify the ratio of binder materials (often Portland and/or lime) in the mortar, and their ratio to sand. There are many different types of mortar analysis including: acid digestion, petrographic mortar analysis, x-ray, compression testing, and many more. The two most commonly used mortar testing methods are the acid digestion analysis of mortar and the astm-c1324 testing method for testing hardened mortars and cement. While each method of testing cement provides useful data, there are no known or commonly accepted mortar testing methods that can provide an exact ratio of the binder materials of a hardened mortar. However, by combining some of the cement analysis methods and performing some other tests of the sample materials, a more accurate and reliable result can be produced.
We offer a wider spectrum of mortar tests to acquire more data about the samples than any other single testing method is capable of providing, and we do offer the basic test of cement individually.
Along with our standard mortar analysis services, AMR Labs provides matching mortar color analysis, and a variety of masonry repair and brick repair products. We produce custom bags of mortar of both Portland cement mortars and lime mortar, and books and videos about how to repair mortar, fix brick, how to mix mortar, how to fix firebox cracks, and more. (Our pre mixed mortars require mortar matching. )
