For residential, commercial, and medium industrial subfloor preparation where rapid turnaround is required, Trulevel Econoscreed Rapid provides a fast-hardening, pre-mixed alternative to traditional sand and cement site mixes. It allows installers to build up ramp areas, grade falls to drains in in-situ shower bases, and patch uneven concrete floors from a thickness of 10mm up to 100mm in a single application.
Trulevel Econoscreed Rapid is a cementitious screed compound formulated to maintain high strength at thin builds while providing water resistance in areas subject to continuous moisture. Because it dries rapidly, it minimizes project downtime by allowing waterproofing membranes and ceramic tile adhesives to be applied on the same day. The dimensionally stable, pre-blended formulation eliminates on-site batching variations and controls the drying shrinkage that causes cracking and efflorescence in traditional sand/cement screeds.
This compound is suitable for indoor and outdoor applications on structurally sound, dry, and clean subfloors. Compatible substrates include:
All surfaces must be mechanically prepared by grinding, abrasive blasting, or blast tracking to remove laitance, curing agents, release agents, and structurally unsound layers. For resilient installations, relative humidity and pH readings must be performed on the concrete substrate in accordance with AS 1884-2021.
Substrates must be primed prior to application; do not apply to an unprimed surface. For porous concrete, dilute one part RLA Universal Primer with two parts water (a second coat diluted 1:3 may be required for highly porous surfaces) and cure for 30 minutes. For non-porous substrates, apply RLA Universal Primer undiluted (neat) and allow to dry to a tack-free transparent film (approximately 1 hour at 23°C).
Mix one 20kg bag with 1.7 litres of clean water using a high-shear stirrer powered by a heavy-duty mixing drill at approximately 600 rpm for two minutes. Spread the wet screed over the floor area immediately to the designated falls using a mortar trowel. When filling holes or cracks, apply firm trowel pressure to ensure complete contact with the substrate. Trim excess material after approximately 10 minutes and finish with a damp steel trowel.
Ceramic tiles can be installed in 4-6 hours, and resilient or timber floor coverings in 24 hours. This rapid cure profile significantly reduces project downtime on site.
Yes, it's designed for continuous moisture environments and can form in-situ shower bases with correct falls. It reduces efflorescence common with traditional sand/cement screeds in wet applications.
You can apply EconoScreed Rapid in a single application up to 100mm thick. This makes it suitable for significant levelling or building up ramp areas.
Yes, priming is mandatory. Use RLA Universal Primer, diluted 1:2 for porous concrete or neat for non-porous surfaces. Never apply to an unprimed substrate.
| Application | Key benefit | Primary trades |
|---|---|---|
| Rapid floor levelling and screeding | Achieves foot traffic in 4 hours, allows ceramic tile installation in 4-6 hours, and resilient/timber in 24 hours, significantly reducing project schedules. | Tilers, Floor Prep Contractors, General Builders |
| Forming falls in wet areas (e.g., shower bases, balconies) | Provides high strength (65 MPa compressive, 10 MPa flexural at 28 days) and excellent water resistance, reducing efflorescence risk in continuously moist environments. | Waterproofers, Tilers, Plumbers |
| Repairing uneven concrete floors (10-100mm thick) | Dimensionally stable formulation minimises cracking and handles significant variations in subfloor height, providing a stable base without the need for multiple products. | Concreters, Repair Contractors, Building Maintenance |
| Underlayment for all common floor coverings | Creates a smooth, hard-wearing surface compatible with RLA adhesives for carpet, vinyl, timber, and ceramic tiles, ensuring reliable performance of the final floor system. | Floor Prep Contractors, Tilers, Timber Floor Installers |
| Building up ramps and access points | Achieves thicknesses up to 100mm in a single pass, forming durable and precise inclines quickly for new builds or refurbishment projects. | General Builders, Access Specialists, Concreters |
Substrate must be clean, sound, and free from laitance, dust, curing compounds, sealers, oil/grease and contaminants. Achieve a strong mechanical key and confirm moisture/vapour requirements for the intended system.
Diamond grind or shot-blast to expose a fresh, sound surface; vacuum with HEPA extraction. Repair cracks/voids and make good weak areas before screeding.
Degrease, then mechanically abrade to remove glaze and provide a uniform profile. Replace loose tiles; fill deep grout lines where required.
For bonded screeds, apply the nominated bonding primer/slurry to the prepared surface and place the screed while the primer remains within its open time. For unbonded/floating assemblies, install a slip layer or insulation as per project design and movement-joint layout.
Evenly prime; avoid puddling. Work the first pass of screed firmly into the tacky primer to ensure monolithic bond.
Lay slip sheet and perimeter isolation as specified. Respect minimum thickness, bay sizes and joint rules for the assembly.
Use clean, potable water and a forced-action mixer or heavy-duty paddle. Maintain consistent powder and water temperatures for predictable set and finish.
Dose approximately 1.7 L per 20 kg bag (within the stated TDS range) to achieve a cohesive, plastic mix that compacts without bleeding. Do not over-water.
Record bag counts and water volume per batch. Mix to a uniform consistency; allow brief rest if specified, then remix. Never re-temper after the mix begins to set.
Place promptly after mixing. Compact thoroughly to remove voids and level to rails/marks. Finish to specified SR tolerance and falls.
Work the first layer into the tacky primer to ensure intimate contact; continue build to the designed thickness, striking off and floating to finish.
Install over the slip layer/insulation; honour bay sizing and movement joints. Maintain minimum thicknesses per design—no feather-edging.
Protect the screed from rain, running water, rapid drying (sun/wind) and contamination during early cure. Observe minimum access and overlay times before membranes, adhesives and floor coverings.
Allow foot traffic from ~4 hours under typical conditions. Lower temperatures and greater thickness will extend this time.
Install the nominated membrane only after the screed meets the minimum cure and moisture criteria. Tile/cover after both screed and membrane (if used) satisfy system requirements.
Reinstate or honour existing movement/control joints through the screed. Provide perimeter isolation at walls/columns as required. Clean tools and mixers with water immediately after use.
Carry joints through finishes according to project details. Avoid bridging structural joints with rigid toppings.
Rinse mixers and tools before set; dispose of slurry responsibly—do not wash into drains or waterways.
Warning: Causes serious eye irritation.
Wear safety shoes, overalls, chemical goggles, and a dust mask. Nitrile rubber gloves are suitable for intermittent contact. Always wash hands before eating, drinking, or using the toilet.
Use in well-ventilated areas. Ensure ventilation is adequate to maintain air concentrations below exposure standards and avoid inhaling dust.
Store in a cool, dry, well-ventilated place, out of direct sunlight and off the ground. Keep containers closed when not in use. Shelf life is 12 months in original unopened packaging. Dispose of material and containers in accordance with local regulations.
Proper surface preparation and correct priming are critical for reliable adhesion and performance of RLA TruLevel EconoScreed Rapid.
Surface prep: Surfaces must be structurally sound, stable, dry, and clean. Mechanically remove all loose material, de-bonded coatings, curing agents, wax, laitance, oils, and grease by abrasive blasting, grinding, or similar. Fill rough areas and voids. For resilient installations, check concrete relative humidity and pH per AS 1884-2021.
Primer: Required. For porous concrete, dilute RLA Universal Primer 1 part primer to 2 parts water. For very porous concrete, a second coat diluted 1 part primer to 3 parts water may be needed. For non-porous concrete, apply RLA Universal Primer neat. Allow primer to dry to a transparent, tack-free film (approximately 1 hour at 23°C).
Surface prep: Ensure surfaces are structurally sound, smooth, stable, dry, and clean. All general surface defects must be repaired, and brick/block surfaces should be pointed flush. Remove all contaminants as per concrete preparation.
Primer: Required. Treat as a porous substrate. Dilute RLA Universal Primer 1 part primer to 2 parts water. Allow to cure for 30 minutes before application.
