Screeding
Precision Screeding in Kurunjang
Why is screeding so important? The appearance of the most attractive tiles becomes compromised when they rest on floors with uneven surfaces. The floor becomes ready for tile installation through proper screeding procedures, which produce a flat surface. The tile floor lifespan increases and its durability improves through screeding which avoids tile lippage issues and prevents cracking and water accumulation on the surface. Our expert floor levelling and screeding services begin the process of creating perfect tiled areas by providing excellent work from the floor base.
Reasons to do Screeding?
Creates a Level Surface: Screeding results in an entirely level surface that ensures proper installation of tiles and flooring, as well as laminate materials. A screed service to normalise subfloor surfaces that also levels concrete.
Provides a Strong Base: A stable concrete base arises from screeding that allows both heavy foot traffic and weight-bearing capacity to reduce the risk of floor damage.
Improves Tile or Floor Adhesion: Tiles and wood flooring as well as vinyl require a perfectly flat smooth surface to attach properly and prevent structure damage to the installation.
Enables Proper Drainage Slope: The necessary water drainage slope in wet spaces like bathrooms and balconies or terraces can be achieved by using screeding which protects against water-related damage such as puddles.
Reduces Sound and Vibration: The application of screed serves to decrease sound transmission across multiple floors in constructed buildings. Floor vibration absorption results from the implementation of screed.
Encases Underfloor Heating Systems: The process of pouring screed over heating pipes or cables within heated floors ensures their stability and maintains uniform heat distribution across the surface.
Supports Heavy-Duty Use: Heavy equipment and machinery need thick screeds that have reinforcement or include an additive to prevent cracking in commercial and industrial areas.
Durability and Longevity: The lifespan of floor systems extends when polymeric or fibrous screeds are utilised since they prevent surface damage and cracking.
Process of Screeding a Floor
Surface Preparation- Clean the subfloor surface by eliminating dust together with debris, and oil, as well as loose materials.
- It is necessary to apply appropriate filler or mortar for fixing both cracks and holes.
- A small amount of dampness on the surface should be applied before screeding when using cement-based screed to enhance bonding effectiveness.
- Set up screed rails or level markers (like metal strips or wooden battens) at the desired height using a spirit level
- These guides help keep the screed at a consistent thickness.
- Ratio: 1 part cement to 3–5 parts sharp sand.
- Add water slowly until the mix is semi-dry (like damp sand—malleable but not runny).
- Start from one corner of the room.
- Pour the screed between your level guides.
- Compact the material thoroughly with a trowel or tamping tool.
- Use a straight edge or screed board ( long aluminium bar) to drag across the top of the screed, using the guides as support.
- Move the bar in a sawing motion to level the surface.
- Fill any low spots and repeat as needed.
Curing
- Cover the screed with plastic sheets, damp burlap, or curing compounds to prevent drying too fast.
- Cure for at least 7 days (longer for thicker screeds or poor drying conditions).
Drying Time
- Allow minimum 1 day per mm of screed thickness (up to 40mm), and longer for thicker sections.
- Moisture testing may be needed before laying flooring (especially vinyl or wood).
