Description

Epoxy Screed – Rapid Cure

CPR 715 – Epoxy Screed – Rapid Cure, is a three pack Epoxy Resin based floor screed designed for application at 4-6mm thickness. CPR 715 – Epoxy Screed – Rapid Cure comprises a BASE component, a CURING AGENT component and a specially graded AGGREGATE component. CPR 715 – Epoxy Screed – Rapid Cure is easy to apply and does not stick to the trowel.

CPR 715 – Epoxy Screed – Rapid Cure is non-dusting, chemical and abrasion resistant, non-slip in nature and may be rapidly opened to traffic.

Typical Properties

• Fast Curing
• Highly durable
• Abrasion and impact resistant
• Non-slip
• Easily maintained
• Excellent chemical resistance
• Low odour

Directions for Use

Surface Preparation Concrete

• Concrete shall be a minimum of 21 days old and/or the residual moisture content shall be below 6%.
• The floor shall then be mechanically prepared by shot blasting, mechanical scabbling, or similar, to produce a clean, exposed aggregate finish, free from dust, dirt, oil, grease, laitance and other contaminants.
• Old concrete shall be mechanically prepared to remove all contaminants.
• Defective concrete shall be removed, cutting back to sound substrate.

Mixing

• The use of a mechanical, forced action mixer such as a Creteangle, is strongly recommended.
• Pour the contents of the CURING AGENT container into the BASE container and mix thoroughly.
• The mixed resins shall be poured into a mixing vessel, (Creteangle bucket or similar), and the AGGREGATE added steadily whilst the mixer is in motion.
• Mix for 2-3 minutes until a uniform material is achieved.

Priming

• Apply a coat of CPR 402 – Concrete Primer – Epoxy WB – Rapid Cure, to the prepared surface at a rate of 3.5 to 7.0 m²/kg (depending upon surface texture).
• Within 60 minutes of the primer application, CPR 715 – Epoxy Screed – Rapid Cure may be applied; i.e. whilst the primer is still ‘tacky’.

Application

• Lay the material, utilising screeding bars or screed box, ensuring good compaction, and finish with stainless steel or chemically resistant plastic float.

Sealing

• The application of a clear sealer is recommended to reduce the tendency towards staining and dirt pick cup, and thereby ensure optimum ease of cleaning.
• Apply 1 or 2 coats of CPR 902 – PU Screed Sealer at a nominal rate of 0.15litres/m² per coat.

Equipment Cleaning

• Clean equipment with CPR 200 – MMA Tool Clean Solvent prior to curing of the screed.

Curing

• Allow to cure for a minimum of 4 hours @ 20°C prior to light foot traffic access and 10 hours @ 20° prior to vehicular trafficking.
• 5 days cure @ 20°C is recommended prior to exposure to chemicals.
• Curing will be slower at lower temperatures.

Storage and Shelf Life

• Store in dry conditions at temperatures between 10°C and 25°C.
• Avoid low-temperature storage prior to use of the material.
• Do not expose to freezing conditions.
• CPR 715 – Epoxy Screed – Rapid Cure has a minimum shelf life of 12 months when stored in original, unopened containers in accordance with manufacturer’s instructions.
