We now manufacture premixed, integrally-colored stucco’s and decorative coatings, only requiring the addition of water at the site. Today, Sider-Crete has taken traditional stucco steps further. It is a proven system that works in all climates. Hard-coat stucco has high impact resistance, sheds water but breaths, allowing water vapor to escape. A vapor-permeable, water-resistant building paper separates the plaster and lath from water sensitive sheathing or framing. When applied to metal lath, two to three coats of stucco are applied. Applied directly to concrete masonry, hard-coat stucco provides a tough finish that is integrally bonded with the masonry substrate. It may be applied directly to a solid base such as masonry or concrete walls, or it can be applied to a metal lath attached to frame construction, solid masonry, or concrete construction. Hard-coat stucco is applied either by hand or machine to exterior and interior wall surfaces in two or three coats. The application of Hard-Coat Stucco: Past & Present Through research and development, Sider-Crete is committed to continue to improve our products to stand against modern day environmental factors to last for years to come. Stucco has stood the test of time through thousand of years. The sintered product was then ground and he called it Portland cement named after the high quality building stones quarried at Portland, England. Subsequently, in 1824, Joseph Aspdin of England invented Portland cement by burning finely ground chalk with finely divided clay in a lime kiln until carbon dioxide was driven off. Then, in 1810, Edgar Dobbs received a patent for hydraulic mortars, stucco, and plaster although they were of poor quality due to lack of kiln precautions. And in 1779, Bry Higgins was issued a patent for hydraulic cement (stucco) for exterior plastering use. It was not until the ~1600 that the interest for plastering/cement resurfaced. However, Plaster saw a sharp decline in interest during the Middle Ages (~1200 to ~1500 A.D.). In earlier times, limestone was the main ingredient but as time passed and technology improved, Portland cement became the ingredient of choice.Īs seen on the photos, exterior plaster is still present on these pyramids, standing thousands of years of weathering from the beaming desert sun, torrid temperatures and freezing nightsįrom ~ 800 to ~ 400 B.C., Greek and Roman civilizations continued to improve the use of limestone for wall plastering. From the oldest known civilization (Sumerian, ~ 4,000 years B.C.) who built the first known city – Uruk (top left) – to the Egyptians Pyramids (~ 2,500 years B.C.), mixtures of different minerals resulting in some form of plaster were found. The Hard Facts About Hard Coat Stucco What is Hard-Coat Stucco? HistoryĪs far back as civilizations existed, traces of plastering appear. ![]()
