Screed is a customized aluminum or flat board that is use to smoothen concrete on a surface. It also helps in leveling plaster. Here are some information on screeding and how to do it. You’ll also identify different types of concrete screed so you can handle different situations properly. Below are guides on how to screed cement, concrete, or base.
- What is screeding? It is the procedure of cutting excess damp concrete so a slab’s top surface will have proper smoothness and grade. It is an easy process to flatten a surface. You have the preference to make it sloped or leveled.
- Prepare the concrete, cement, or base. All experienced handyman understand that it’s a rare chance to get an accurate smoothness or elevation of concrete after it’s been poured. Circumstances like the process the concrete is handled from a truck, the weather and other elements affect the concrete. One effective way to attain proper smoothness and elevation is by using a screed.
- How to screed. The screed must be dragged across the concrete that is freshly poured on a surface. Note that the surface of the screed is normally flat and smooth. However, you can shape it to your desired formation to attain your preferred surface like concave or curved.
- There’s no similar concrete pour and size so various kinds of concrete screed exist. As a craftsman, you need to have the proper tools for the situation.
- Hand screed. It’s like a long board that has two handles. The length of hand screeds can vary. However, they aren’t efficient for 30-foot wide surfaces or bigger. The suggested size is only 10 feet. This screed must rest on the concrete form’s edges as the screed operators move the screed across the concrete’s surface to fill voids and remove excesses.
- Mechanical screed. It’s much advanced than hand screed. It can be utilized on broader surfaces like roadways and bridges. It is also capable of vibrating the concrete while it’s being screed so it saves an operator’s time in finishing the concrete. The vibrating procedure makes the concrete compact.
- Roller screed. It can be six to 43 feet long. It resembles a seamless and long pipe. This screed is like a hand screed in the process that it rests on concrete form while it’s dragged. However, it’s not similar to a mechanical screed because its motor makes it revolve in the reverse path where it’s pulled. It also has a vibrator that compacts concrete. This screed is best utilized on inclined surfaces.
- Truss screed. It’s like a roller screed that can screed an area up to 65 feet. Its truss design stabilizes this screed to span wider spots without torquing or twisting. It also helps to make concrete more compact by vibration.
- Magnesium screed. It’s another type of hand screed. It is made of magnesium so it’s not heavy to operate. You can screed areas up to 24 feet long. This screed is a favorite of concrete operators.
