Liquid floor screed is made from sharp sand and cement together; it can be applied to sites under construction or on a completed foundation floor. It is also known as anhydrite screed, used as a calcium sulphate binding agent in exchange for cement. However, it is very similar to traditional concrete and works similarly. To provide a smooth and fine finish, it is poured on top of a concrete layer, on which carpeted or wooden flooring can be fitted very easily.
Why should you use liquid screed?
- Liquid Screed Basingstoke has gained popularity among homeowners who install underfloor heating. It is a relatively cost-effective and easy way to create a floor that provides a level and an even floor.
- Liquid scree is quick to install and can be laid easily; you won’t have to pour it piece by piece due to its flowing nature like you do with dry screed.
- Thanks to its self-levelling abilities, it provides a fine and smooth finish for numerous types of floors, such as linoleum, tile, vinyl, wooden and carpet flooring.
- It reduces the risk of cracking; it is ideal for places with more footfall, which is best for industrial and commercial flooring.
- It is fantastic for those who want to install underfloor heating as it’s more conductive than traditional screed. It seamlessly settles around pipes, and the effort required to pour it will be much less.
- It is less prone to shrinkage than traditional screed and needs far fewer expansion joints.
- Furthermore, it dries faster than traditional screed or other materials. surprisingly, it takes only 24-48 hours to walk on.
- Lastly, when choosing liquid screed, you never have to worry about lumpy and bumpy surfaces.
Some environmental benefits of liquid screed are:
- Due to its great thermal conductivity and spreading heat evenly across the floor makes the building more energy efficient.
- Liquid screed is thinner, which means fewer resources are used, and less energy is required during production.
Where can liquid screed be used?
Liquid floor screed can be used commercially, domestically, or almost anywhere indoors. This is also best in environments that are prone to high temperatures.
It is extremely useful if you are laying a new floor on top of the existing one, filling each gap and spreading evenly in each corner.
Remember always to cover the screed floor because if left uncovered, it is not ideal for damp areas like bathrooms and wet rooms.
How do you prep a floor for screed?
With liquid screed, it is essential to get the preparation right:
- First, you have you tank the floor like a mini swimming pool by using a polythene sheet membrane.
- In most cases, surfaces that are to be screened consist of 50-100mm thick layers of insulation boards.
- The best insulation layer must be lined with polythene sheeting to halt the liquid escaping.
- Lining helps in preventing any potential chemical reaction with the installation underneath.
- Any rough obstacles and plumbing may need temporary formwork to ensure 100% water tightness.
- To contain the liquid, polyethene sheets are lapped up to the walls and glued with spray adhesive. This is an addition to existing layers, such as the damp-proof membrane, thin strips of compressible foam, and insulation strips around the wall edges designed to accommodate any expansion once the Liquid Screed Bracknell is dried.
- The final step is to scrape off any lumps or debris and tape all the joints, so they don’t float up to the surface when the liquid screed is poured.
Screed options to choose from
There are five types of screeds to choose from, each one designed to be used in specific situations.
- Bonded screed: bonded screed will be fixed or attached to the substrate using a primer or an agent and is extremely great for thin flooring sections designed to hold up heavy objects.
- Partially bonded: the most affordable screed is a partially bonded screed, but it is not durable. To make sure it does not break easily, it needs to be at least 50mm deep.
- Unbonded floor screed: this screed is not bonded directly and is separated by a membrane. It is self-levelling and made from cement and sand and sometimes calcium sulphate.
- Floating screed: is applied over insulation. It insulates well, and with the right kind of edging and insulation foam, it needs to be kept from shrinking.
- Liquid screed:mmade with specialized materials and characteristics, liquid screed is superior to traditional screed mixes. It is fast drying and fast setting screed than other materials. This is far the higher-ranking type of screed because it can handle all commercial and domestic traffic.
