Portland cement-based plaster is such a material that uses portland cement as the binder. There are several issues; the most common being the use of the wrong (interior vs. exterior) agent and the use of non-compliant (ASTM C932) exterior agents. A fog coat is a light application of a cement-based slurry, the same proportions of cement, lime (if any), and water as used in the original application minus the sand, used to even out a surface’s appearance. crete Bonding agent failure. These finish coats are often made with white cement and pigments, providing the widest range of colors. Sto Bonding Agent and Admixture 80245 Sto Bonding Agent and Admixture Technical Data Sto Bonding Agent and Admixture is an acrylic latex for bonding StoPowerwall® Stucco to properly prepared concrete and concrete masonry. Southcrete 45 Concrete Bonding Agent is a poly-vinyl acetate emulsion that can be used as a primer for binding over various substrates such as concrete, stucco, brick and stone. bonding agent is a patented formulation incorporating polyvinyl acetate homopolymer. Trowel. Certain parts of the country may call a specific texture by another name than described by the TSIB. It can, however, be adequately accomplished by preventing evaporation of moisture from the plaster—and placing the next layer of plaster on top of the other does that. Bonding agent is used to keep moisture from the new stucco from soaking into the existing wall, which minimizes cracks and damage over time. You always should test the method on an inconspicuous area to first demonstrate its effectiveness and to assure that it won’t damage the plaster. 2. ASTM C1063, Installation of Lathing and Furring to Receive Interior and Exterior Portland Cement-Based Plaster, provides guidance on the size of metal lath, number and length of fasteners, and appropriate spacing of contraction joints. Stucco a Masonry or Concrete Wall. That is why this site is so beneficial: it provides visual depictions of each finish to prevent misinterpretations that might occur with verbal descriptions. When stucco is applied to any construction using metal lath, joint spacing recommendations should be implemented. That means that many materials are suitable for this application, but the common ones remain plywood, oriented strand board (OSB), cement board, and exterior grade gypsum sheathing. Water. It is possible to paint with other types of paint, though these are usually not as long lasting as cement-based paint. Bonds concrete, plaster, and more to difficult surfaces Add to patching cement to increase the resiliency and elasticity of the patch Improves the performance of … Shop concrete, cement & stucco mix and a variety of building supplies products online at Lowes.com. After Grade D is a water-vapor permeable paper. No length should be greater than 18 feet in either direction. The metal lath may add a small additional amount of weight, so the end result is that three coat stucco weighs about 10.4 pounds per square foot (psf) installed. After the bonding agent has dried, the next step in applying stucco to masonry is to add the first coat of stucco. such as concrete, old stucco (unpainted), is wet down. A bonding agent (bonding adhesive) needs to be painted onto the existing concrete first to ensure that the fresh concrete will successfully adhere. Dip the paint roller into the paint tray and apply the bonding … The three coats consist of two base coats and one finish coat. Bonding agent should be applied by brush or roller to at least 0.25 mm film thickness. Concrete Bonding Adhesive has very strong adhesive characteristics that eliminate the need to roughen up the surface of the existing substrate before applying new material. band-aid patches. Epoxy based, multipurpose, bonding agents for use on concrete, steel and other substrates. The acrylic mortar mix can be troweled on Use of Whitecap Bonding Agent is appropriate for new or existing concrete, stucco and masonry construction. For cast-in-place or precast concrete, the thickness for two-coat work is 3/8 inch. / Concrete, Cement & Stucco Mix / Masonry Additives. 2020 Energy and Environment Award Winners, 2020 Chairman’s Manufacturing Performance Award Winners, 2019 Chairman's Safety Performance Award Winners, 2019 Chairman’s Manufacturing Performance Award Winners, State & Market US Summary (13 Categories, 1 Year), State & Market Trend (46 Categories, 20 years), Construction PIP by State (23 Categories, 20 years), Resiliency Potential in the Wildfire-Prone Single-Family Market October 2020, The Potential Impact of Tariffs Levied Against Chinese Cement, Railway-Related Cement Consumption Outlook, Trump Infrastructure: Potential Taxpayer Savings from the Use of Life Cycle Cost Analysis (LCCA), Attitudes & Perceptions Study: Soil Cement, FDR and RCC Pavement Market, Long Term Cement Pavement Consumption Outlook, Energy-Related Cement Consumption, September 2017, Airport-Related Cement Consumption Outlook, July 2017, U.S. Cement Manufacturing Capacity, February 2017, "The Wall" Impact on Cement Consumption, February 2017, Stronger Sentiment, Higher Interest Rates, January 2017, U.S. Portland Cement Industry: Plant Information Summary, Leadership in Energy and Environmental Design, COVID-19 State Resources and Environmental Policies, MIT Concrete Sustainability Hub Pavement Research, Cement-Stabilized Subgrade (CSS) Soils and Cement Modified Soils (CMS) Case Histories, Full-Depth Reclamation (FDR) Case Histories, Roller-Compacted Concrete (RCC) Case Histories, Roller-Compacted Concrete (RCC) Performance, Find a Roller-Compacted Concrete (RCC) Contractor, Storm Water Management by Pervious Concrete, Sustainable Cement & Concrete Manufacturing Toolkit, Sustainable Cement & Concrete Construction Toolkit, Design and Control of Concrete Mixtures Course, Troubleshooting: Solutions to Concrete Field Problems, Mill Grinding Course and Kiln Process Program, Masonry Walls and the Importance of Mockups, Verifying Compressive Strength of Masonry, The Masonry Society Becomes Sole Sponsor of Code and Specification, Special Inspection in the Codes and Standards, Placing Joints in Concrete Flatwork: Why, How, and When, The Difference Between Curing and Drying Concrete, exterior insulation finishing systems (EIFS). Curing compounds are effective for concrete but are not used regularly on plaster. Most dirt is removed fairly easily. Paper should be lapped like siding, meaning that upper layers are placed over lower layers. You can’t put the stucco directly on to the brickwork. I have been told that can get away without sandblasting the old stucco and just applying the Many homes built in the early 1900s have had very little maintenance and remain in good shape today. Base coats, of which there may be one or two (sometimes scratch and brown are combined), can be wetted once they have developed adequate strength so that they are not washed away by the water. For unit masonry, that thickness is ½ inch. The rules for the maximum spacing between joints and the maximum size of panel are well established and discussed in a separate FAQ on. While these materials may be more rugged than paper—and therefore less prone to damage during installation—a single layer is still not adequate according to many industry professionals. Most of the surface is covered with the plaster. Plaster placement speed waster is increased significantly along with significant reductions in mortar droppings and this results in greater worker productivity, project delivery improvements while upgrading the plaster and stucco job finish quality. Some people use an EIFS basecoat material as the glue. The recommendations found in the Portland Cement Plaster/Stucco Manual, EB049, are based on ASTM C1063, Standard Specification for the Installation of Lathing and Furring to Receive Interior and Exterior Portland-Cement Based Plaster. Portland cement plaster has high impact resistance and sheds water, but breathes, allowing water vapor to escape. This often occurs on the same day (see the footnote to the table above).
