A List of Screed Products used in Floor Screeding
O. C. Floor Screeding provide high quality level screed at competitive prices for your commercial and domestic contracts. We can provide you with screeders for traditional sand and cement, polypropolene (PP) reinforced fibres, polymer bonded and fast drying screeds. We welcome your small and large projects and can offer screed for your underfloor heating system (UFH). Contact us if you require floor screed in London, M25 and South East areas of the UK.
The list below helps explain the difference in the types of screed products used in floor screeding.
•Sand and Cement Screed
Sand and cement screed is otherwise known as traditional screed. Sand and cement are the components of screed and are combined together with water using a screed pump or mixer. Sand and cement screed is ideal for every situations such as ground floor slabs, suspended floors and as a lightweight topping. It can also be used over insulation and with underfloor heating.
Fibre screed, also called PP fibre screed or reinforced screed, is ideal in any situation especially sites with high foot traffic and can be used with underfloor heating systems. Polypropylene fibres (referred to as PP fibres) are combined with sand and cement screed. The use of fibres inhibits shrinkage cracking, reduces settlement cracking, improves cohesions, increases strength, permeability and the screed is more shatter and impact resistant. It can also be used over insulation and with underfloor heating.
Polymer Screed is ideal for concrete ground floor slabs, precast concrete, suspended floors and when a thinner depth is required. It combines sand and cement screed with a polymer resin, such as a SBR Bonding Agent. It is a very high quality bonding agent in which a carboxylated styrene butadiene copolymer latex (SBR) replaces conventional PVA. This increases durability, reduces shrinkage and cracking, increases flexibility and toughness, permeability and bonding strength. SBR latex, unlike PVA, cannot be re-emulsified once cured. It can be used over insulation.
Anhydrite screed, refered to as flo, flow, poured and liquid screed, is ideal for commercial buildings. It is a self leveling screed which is poured directly onto a floor for a fast application of 2000 square meters. Anhydrite screed reduces cracking, is light weight, protein free, environmentally friendly and high strength. It can also be used over insulation and with underfloor heating.
•Fast Drying Screed
Fast Drying screed is a combination of sand, cement and an admixture such as Isocrete K-Screed, Ronacrete Uniscreed or alternatives. It is suitable for interiors and exteriors. It is a specialist hydraulic binder which allows for rapid drying and will harden within 24 hours and become completely dry within approx. 7 days. It can also be used over insulation and with underfloor heating.
Latex or Waterproofer Planicrete is added to mortars, screeds and renders to increase mechanical strength and adhesion to the substrate. It is a synthetic rubber latex for improving adhesion of cementitious mortars and is a latex based on synthetic polymers, which cannot be re-emulsified in water after hardening and are also resistant to saponification.
