SynLime allows masonry and stucco professionals to eliminate Type S Lime from their batches and mixes. And better yet, SynLime doesn’t require the use of fly ash, clay, diatamaceous earth, or other additives required with lime.
SYNLIME™ is specifically formulated to produce high plasticity and excellent water retention. The end result is a more workable mix with higher PSI levels that is clean, safe, and worker friendly. Its increased bonding strength to foam and wire is also superior to lime. Is there a safe alternative to lime in stucco? The answer is a resounding yes… SYNLIME™.
Mortar or Masonry Bond refers to the adhesion of the joint mortar to the masonry units or to the reinforcing steel.
Increase your masonry bond by utilizing a patented new admixture called SynLime.
Pattern bond refers to the pattern formed by the masonry units and mortar joints on the face of a wall. The pattern may result from the structural bond, or may be purely decorative and unrelated to the structural bond. Figure 8-33 shows the six basic pattern bonds in common use today: running, common or American, Flemish, English, stack, and English cross or Dutch bond.
The running bond is the simplest of the six patterns, consisting of all stretchers. Because the bond has no headers, metal ties usually form the structural bond. The running bond is used largely in cavity wall construction, brick veneer walls, and facing tile walls made with extra wide stretcher tile.The common, or American, bond is a variation of the running bond, having a course of full-length headers at regular intervals that provide the structural bond as well as the pattern. Header courses usually appear at every fifth, sixth, or seventh course, depending on the structural bonding requirements. You can vary the common bond with a Flemish header course. In laying out any bond pattern, be sure to start the corners correctly. In a common bond, use a three-quarter closure at the corner of each header course. In the Flemish bond, each course consists of alternating headers and stretchers. The headers in every other course center over and under the stretchers in the courses in between.
The joints between stretchers in all stretcher courses align vertically. When headers are not required for structural bonding, you can use bricks called blind headers. You can start the corners in two different ways. In the Dutch corner, a three-quarter closure starts each course. In the English corner, a 2-inch or quarter closure starts the course.The English bond consists of alternating courses of headers and stretchers. The headers center over and under the stretchers. However, the joints between stretchers in all stretcher courses do not align vertically. You can use blind headers in courses that are not structural bonding courses.The stack bond is purely a pattern bond, with no overlapping units and all vertical joints aligning. You Must use dimensionally accurate or carefully re matched units to achieve good vertical joint alignment. You can vary the pattern with combi-nations and modifications of the basic patterns shown in figure 8-33.This pattern usually bonds to the backing with rigid steel ties or 8-inch-thick stretcher units when available.In large wall areas or load-bearing construction, insert steel pencil rods into the horizontal mortar joints as reinforcement.The English cross or Dutch bond is a variation of the English bond. It differs only in that the joints between the stretchers in the stretcher courses align vertically. These joints center on the headers in the courses above and below.When a wall bond has no header courses, use metal ties to bond the exterior wall brick to the backing courses.
Masonry cement is now available without the need for lime. Until recently, finding a safe alternative to replace lime in stucco, plaster, grout, and mortar was a difficult proposition. Type S lime has been a long time staple for those requiring their mix to remain fluffy and sticky. Afterall, workability is a must. But finally, there’s a safe alternative that won’t burn skin, irritate eyes, or get you all choked up.
SYNLIME™, from Admix International, is a safe 100% complete lime replacement. Unlike the failed attempts of liquid additives or powdered lime reducers – SynLime™ is a COMPLETE lime replacement that also eliminates the need for other lime additives such as fly ash, clay, diatamaceous earth, etc. And SynLime™ doesn’t reduce workability. SynLime™ makes the mix fluffy, sticky, & very workable!!
