Easi-Screed is ideal for both industrial and domestic use. It is dust free and can be used untreated as a wearing course. Alternatively, Easi-Screed will accept an epoxy coating to achieve a smooth, seamless and impervious floor. It is also ideal for use under tiled areas, carpets and linos in both commercial and domestic applications.
Suitable Substrates
Easi-Screed Standard can be used to overlay concrete, cement screeds, stone, quarry tiles, terrazzo, brick and block.
Colour
Easi-Screed Standard is grey in colour.
Packaging
Easi-Screed Standard is supplied in 25kg bags.
Preparation
Thorough substrate preparation is essential.
The surface should be clean, sound and free from all loose particles such as old adhesive residues, dust, plaster spillages, grease, paint, polish and any other compound, which may become softened by the introduction of water or be detrimental to the required bond. All laitance should be removed by mechanical means such as shotblasting or scrabbling, to ensure a sound sub-base suitable to receive the screed. Remove and replace with concrete and sand/cement screeds must be dry and any laitance or surface treatments removed.
Sand/cement screeds must have a moisture reading of less than 75% RH before work can begin. The screed may be applied onto a suitable surface damp proof membrane where a good mechanical key has been provided. This may be achieved by applying dry silica sand to the second coat of DPM whist it is still wet. Single part screed is not impermeable to water and should not be used when damp conditions prevail. Underfloor heating must be switched off at least 48 hours before and after application. Temperature should then be increased by 5°C, at 24 hour intervals.
Mixing
Add 4.5L of clean water into a clean suitable container. Gradually add the entire 25kg quantity of powder whilst mixing with a heavy duty slow speed drill and mixing paddle. Mixing by hand does not readily give a thoroughly or evenly mixed product.
Mix for at least 3 minutes until a smooth lump free consistency is achieved. Allow the mix to stand for 2-3 minute and mix briefly for 1 miniute, afterwards the free-flowing screed will be ready for application directly onto the prepared substrate.
Mixing by hand is NOT advised. For larger areas or greater thicknesses an appropriate mixing pump is more suitable. Ensure thorough mixing as an unmixed product will result in a poor or non-cure situation. Do not mix more than can be applied in 25 minutes or add excess water.
Application
By trowel or pump. Trowel: pour a small quantity onto the prepared surface and trowel down lightly to a depth of between 3mm and 15mm. Periodically check to ensure mix remains in limit. We advise the use of a spiked roller to ensure a close tolerance surface is achieved. Pump application: Easi-Screed Standard is suitable for use in conjunction with professional mixer pump systems, enabling continuous application of large areas. Please contact Polycote Technical Helpline.
Easi-Screed Standard must be left to dry before applying the final decorative surface flooring. This is generally after 24 hours, although it can vary and be faster depending on the
choice of surface flooring. This is generally after 24 hours, although it can vary and be faster depending on the choice of surface flooring.
Cementitious screeds are susceptible to damage from liquid and chemical attack (including prolonged or constant use of water) and should therefore be sealed suitably prior to the use of such products.
Application Thickness
The recommended range of applied thickness is from 3mm minimum to 15mm maximum in one layer. For filling deeper areas please contact the Polycote helpline for advice.
