Levelling Compounds
Levelling compounds are specialist products designed to smooth out irregular and uneven floor surfaces, forming a solid, level base ready for coatings and coverings. These self-smoothing blends are essential for creating the perfect surface prior to the application of finishes like concrete floor paint, helping to avoid future cracking, bubbling, or wear issues. Their ability to bond to multiple substrates - including concrete, tile, screed, wood, and metal - makes them a dependable option across residential, commercial, and industrial settings.

Buy Self-Levelling Compounds for Concrete and Screeds
Levelling compounds provide a flat, durable surface for floor coatings, tiles, and bagged materials, particularly in renovation and refurbishment work. These flowable compounds fill hollows and correct gradients in floors before finishes are applied, ensuring that coatings adhere properly and perform to their full potential. Their use is especially beneficial in areas subject to continuous wear or loading.
From domestic refurbishments to high-traffic environments, levelling compounds are trusted for their ability to deliver high compressive strength, rapid curing, and compatibility with a wide range of finishes, including garage floor paint. Whether applying by trowel or pump, they support precise preparation across concrete, screeds, and even metal or tile bases. Fast-set options also help reduce downtime in time-sensitive environments.
Levelling Compounds FAQs
Can I use a levelling compound on a painted concrete floor?
Yes, but only if the paint is sound and firmly bonded. Any weak or flaking paint must be removed to ensure adhesion.
Do levelling compounds need priming beforehand?
Yes, a primer is typically required to improve adhesion and reduce absorbency of the substrate, helping prevent early drying or cracking.
Are all levelling compounds suitable for external use?
No, many are designed for internal floors only. Products intended for external or damp environments must be specified accordingly.
