Rust-Oleum Speed Screed

Rust-Oleum Speed Screed

This product is a pourable, durable and rapid way to smooth uneven, damaged or worn concrete floors.

Rough concrete floors can be transformed rapidly and easily with this self-smoothing, hard wearing material designed to meet the demands of industrial use. Rust-Oleum Speed Screed gives a mid grey, non dusting, slip-resistant surface that requires no further treatment before use. A mixing paddle for an electric drill and a spiked roller are available for use with this product.

Features & Benefits

• Extermely durable - even withstands forklift trucks
• Foot traffic possible after 6 hours
• High mechanical strength
• Can be over painted with most Rust-Oleum floor coatings
• Low odour
• From 3 – 15 mm thickness possible
• Suitable for interior and exterior use

Theoretical Consumption

As a guide, a 25 kg pack will cover 3.75 m² at 3mm thickness, 2.25 m² at 5 mm thickness, 1.13 m² at 10mm thickness.

Practical Consumption

Practical coverage depends on many factors such as porosity and roughness of the substrate and material losses during application.

Surface Preparation

Concrete should be free of loose material, soft surface laitance and contaminants. New concrete must be at least four weeks old. Remove all loose material by wire brushing. General dirt etc., should be removed with a strong neutral cleaner. Oil and grease can be removed with ND14 Cleaner/Degreaser. Cracks in concrete should be raked out and all loose material removed.

Directions For Use

• Priming: Two primers are supplied. Dampen areas of bare concrete with clean cold water and leave for 20 - 30 minutes prior to applying Primer 1. Apply Primer 1 to the prepared surface using a brush or soft broom. Apply the Primer evenly avoiding ‘ponding’ on the surface and allow it to dry. Then apply Primer 2.
  
• Mixing: (immediately after Primer 2 has been applied) Pour the resin into the empty Speed Screed container. Add the powder to the liquid slowly and blend in using a slow speed electric drill fitted with a paint stirrer until a completely even colour and consistency is obtained (3 to 5 minutes).

Application Conditions

Ambient temperature of approximately 15ºC - 20ºC and good ventilation. Lower temperatures will retard curing. Do not apply at less than 5ºC.

Application & Thinning: Rake/Trowel

Pour the mixed components onto the wet Primer 2. Use a trowel to spread the Speed Screed across the surface of the concrete at the desired thickness (it may be convenient to work to a thin batten but this must be removed before working further sections). It is not essential that trowel marks are removed at this stage. Immediately after application a spiked roller should be used to even out the material and release any trapped air. Use the spiked roller quite vigorously rolling each area 3 or 4 times from different directions. The spiked roller should not be used for more than 20 minutes as the Speed Screed will have started to cure and the roller may leave marks. If it is necessary to walk on areas of wet primer whilst applying Speed Screed care should be taken not to tread wet primer or Speed Screed onto surrounding surfaces.

Remarks

The surface is inherently anti-slip in dry conditions. When fully cured, Speed Screed can be cleaned with detergents or degreasers. Do not subject to temperatures in excess of 60ºC. The surface may become stained by certain contaminants. We recommend painting Speed Screed if a more easily wiped clean finish is required. Do not apply at less than 5ºC. Temperatures over 25ºC can make the material a little sticky to apply and lead to rapid drying out causing surface crazing. During the curing process it is important to have a good ventilation.
