![]() It also results in a neat finished appearance. When a home or building’s foundation may require waterproofing below grade, in future years after initial construction (often 25 to fifty years later) part of a comprehensive job will involve inspecting and repairing any shaled parging which may have resulted over time.Įxposed portions of foundations which are visible above grade are commonly parged to provide extra protection for the poured concrete or block construction foundation walls. Parging the surface of the blocks provides for a clean, smooth surface, for which waterproofing coatings may then be applied. Such work typically falls in the domain of the mason’s craft.įor example foundation walls which are constructed with cement blocks, are recommended to receive a coating of cement over the exterior portion. Such elements can include latex-based colours, fiber materials designed to add strength, or different mix ratios in the concrete itself, depending on the purpose of the application. Parging cement can have several variations in terms of the elements used in the particular concrete mixture used. Most common is the process of parging over a masonry foundation wall or a masonry chimney. Shandong Huiguang has passed through ISO9001, ISO14001, ISO45001,REACH international quality management certification.The process of parging generally refers to the application of a cement coating, which is applied over a wall surface, such as over a foundation, or exterior wall. Our company can produce 50000 tons every year for Hydroxypropyl Methyl Cellulose(HPMC), Hydroxyethyl Methyl Cellulose (HEMC), Hydroxy Ethyl Cellulose (HEC), Methyl Cellulose (MC) etc. Our products can be widely used in Plaster & Grouts, Adhesives, Paints & Coatings, Cement Extrusion, Oil Drilling, Personal Care, Food, Pharmaceutical etc. Shandong Huiguang Technology Development Co.,Ltd is a one of the most professional cellulose ether manufacturer in China, we are located in Binzhou City, Shandong Province. We also can customize modified products according to the customers' specific requirements.įor manufacturers of skim coats and wall putty, we are always looking forward to offer quality products and professional technical service. HAOLOSE Cellulose ether HMC-0572 (40,000-50,000 mPa.s Brookfield RV, 2% wet solution, 20℃) is a modified product which specifically designed for wall putty and we also offer different grades for skim coat application, etc. The main function of HPMC/HEMC in skim coat and wall putty is to thicken and retain water, providing well-balanced properties including open time, slip resistance, adhesion, good impact resistance, and shear strength. ![]() Then, there’s spot priming and finally the wall is ready for the topcoat.Īs an indispensable admixture, Hydroxyethyl Methyl Cellulose (HEMC) and Hydroxypropyl Methyl Cellulose(HPMC) are widely applied in Skim coats and wall putty. It’s used to go over any final surface defects. ![]() When painting a new wall and a primer has already been applied, putty is the next step. Wall putty, on the other hand, is part of the painting system itself. Proper surface preparation helps ensure the wall is in the best condition before it’s painted. ![]() Note how skimcoat comes before putty:īecause skim coat is applied on bare concrete, it’s used during surface preparation (or before the painting process). Here’s a quick overview of the step-by-step process of painting a concrete wall. Knowing that, another difference between skim coat and wall putty is when in the painting process they’re used-basically, if you’re using both for a project, skim coat comes first before putty. Skim coat is applied on bare concrete and commonly over a large surface area such as the whole of a wall to correct waviness. Wall putty is applied on a surface that already has primer or paints and is more commonly used over smaller areas such as when spot correcting minor imperfections like hairline cracks. There is a difference in what they’re applied on too. Wall putty is for minor imperfections such as hairline cracks and slight unevenness on a primed or painted wall. It’s also used to give walls a smoother texture if the bare concrete is rough or bumpy. However, to put it simply, the skim coat is for more noticeable defects such as honeycombs and waviness on bare concrete. Both skim coat and wall putty correct surface imperfections and defects.
