A table of control joint spacing recommendations (attached) appears in the reference document; The use and spacing of stucco control joints depend on several factors: type of materials, the orientation of the building, and the type of surface.Stucco can be applied over concrete and masonry surfaces and will only require joints over concrete or where there is a change in material. E.g. It is generally 20 – 25 times the thickness of the slab. For best performance, the vertical reinforcement should be placed in the cell immediately adjacent to the opening. Best, Mongo The system is very easy to use. They are used with tile between 3/16 in. A typical grout joint width would be 3 times the variation in tile size. Expansion joints are much different and, frankly, far more important, especially around pools. The following information is to show the proper methods and materials for installation of movement joints in tile and stone applications. But with bathroom tile installations, every detail is key.. Control Joints - Dimensions and Spacing The spacing of Control Joints is related to the thickness of the concrete or mortar slab. Install the caulk after the tiles have been set and before the grout is installed. This type of joint is a plane surface between two sections of concrete-concrete placed against concrete already in place which has hardened to the extent that consolidation cannot be effected by vibration or re-vibration. Maximum control joint spacing per Table 1 st nd. Ardex generally state that 4.5m is the maximum allowable spacing. Measure the variation in size from one tile to another. (The standard for joint spacing is 1.5 x the width of the slab. Since the slab will mostly be covered by ceramic tile, minimizing visible joint lines is preferable, but only so long as the design is sound. if you have a 4-foot skirt of decking, the joints should traverse the deck at no more than 6 feet apart. The clips (A) can provide 1/16 in. A similar ratio applies to larger slabs for joint spacing.) When installing wall and floor tiles, technicians place plastic spacers between each one to ensure the lines remain uniform.Tile spacers range in size from 1/16 inch to 1/2 inch. Table 1 indicates a maximum control joint spacing of the lesser of: a length to height ratio of 1½ : 1, which corresponds to 1½ x (20 ft) = 30 ft (9.14 m), or; control joints spaced every 25 ft (7.62 m). Example, the tiles are within 1/16th" of each other, then use a 3/16th" grout joint. Control joints to include expansion joints, saw cuts and other joints in concrete slabs and walls. It includes clips (A), wedges (B) and pliers (C). 4 NCMA TEK 10-2C each side, or a horizontal bond beam could be used, as shown in Figure 2d.

The following are among the recommended products for the installation of tile or stone using the movement joint method on interior floors (dry areas). Tile Was Installed Over a Control Joint . Control joints in concrete are essentially preplanned cracks. Since it is almost certain that concrete will crack at some point in the future, control joints allow you to place those cracks in a predictable fashion. The Masonry Detailing Series (MDS) is an exhaustive collection of illustrative construction details and diagrams produced by International Masonry Institute (IMI) for architects and engineers to use as a … Below is the control joint spacing specification I am referring to. In this example, the maximum spacing of 25 ft (7.62 m) governs over the length to height ratio. Caulk the grout gap between two adjacent rows of tile all the way across the floor. There are perimeter movement joints that allow tiles to expand when butting up … The maximum recommended control joint spacing for walls and ceilings without perimeter relief is 30 feet. Stucco Control Joints: Joint Spacing . However, due to congestion in the cell at this Selecting the right width for grout lines on your tile project may seem unimportant compared to picking tile sizes, patterns and materials.
