RonaScreed FastDry Prompt 20l

RonaScreed FastDry Prompt is a fast-drying liquid additive for site-batched screeds, designed to rapidly reduce retained moisture and allow floor coverings to be laid much sooner than with conventional screeds. Supplied in concentrated form and used in low dilution, it promotes rapid strength gain and early access for following trades. At 50mm thickness, moisture-sensitive floor coverings can be laid after just 4 days; at 75mm and 100mm, after 6 days. Underfloor heating commissioning or use of dehumidifiers can begin after just 2 days at 75–100mm thickness. Suitable for bonded, unbonded and floating installations at thicknesses from 35mm to 100mm. Each 20 litre unit covers 1–2m³ of screed depending on dosage. Available in 5, 20, 210 and 1000 litre units.

• Moisture-sensitive floor coverings can be laid after 4 days at 50mm, 6 days at 75–100mm
• Foot traffic permitted after 24 hours at 20°C
• Compressive strength: 23 N/mm² at 1 day, 48 N/mm² at 28 days
• UFH commissioning or dehumidifier use can begin after just 2 days at 75–100mm thickness
• Suitable for bonded, unbonded and floating screed applications
• No specialist licensing required — can be used by competent screeding contractors
• Supplied in concentrated form for use in low dilution

Good to know

• Minimum thickness: 35mm bonded, 50mm unbonded, 65mm floating (residential), 75mm floating (all others)
• Drying data based on 20°C and 65% relative humidity — low temperatures and high humidity will delay drying
• Not designed as a wearing screed or topping — screed should be covered with carpet, vinyl, tiles or other floor finishes
• Shelf life: 9 months in sealed containers stored in cool, dry conditions, protected from frost
• Available in 5, 20, 210 and 1000 litre units; full pallet (24 units) also available
