Compliances/Approvals

Compliant with BS EN 1871 Physical Properties.

The management system of Swarco Hitex Traffic Safety Ltd has been assessed and registered as meeting the requirements of BS EN ISO 9001 and BS EN ISO 14001.

Technical Data

Swarco Hitex Puma products require the use of a catalyst system to enable curing.

When surface applied glass beads are used to provide initial retroreflectivity, the use of MMA compatible coated beads (such as AC02 or AC05 coated grades) is recommended.

* Dependant on ambient temperature and catalyst dosage

Application Details

• The installation and composition of PumaBrite Screed Road Marking System shall be as stated in the product specification and method statement.
• PumaBrite Screed Road Marking System consists of a Methyl Methacrylate binder, blended fillers, pigment(s), and property modifying additives.
• A programme of work shall be agreed with the purchaser prior to commencement of installation. Requirements for the provision of sufficient working area, plant, safety and, if required, protection to the system shall be agreed.
• The current installation method statement together with all the necessary Health & Safety data sheets and COSHH risk assessment shall be deposited with the purchaser and maintained on-site.
• Every batch shall be subject to visual quality control checks to ensure compliance with the system specification.
• Each component received on-site shall be logged and stored to prevent contamination or deterioration, in accordance with the manufacturer's instructions.

Suitability of the Road Surface

• The system is deemed suitable for use on Highways with concrete or bituminous surfaces.
• The purchaser should ensure that the pavement structure is adequate to support the traffic without undue cracking or deformation during the expected life of the system.
• New bituminous substrates should be allowed to weather for at least 6-8 weeks prior to the installation of the system. This is because new bituminous substrates can contain residues of oils and additives which can inhibit adhesion and curing. Depending on the type of substrate, this can take even longer than 8 weeks, and tests should be carried out on a small area. Use of a primer or applying an initial thinner coat of PumaBrite can help to reduce bleed through of bitumen. Allow the first coat to fully cure before applying a second coat on top.
• Concrete surfaces should be a minimum of 28 days old and must be primed using a Swarcoplast Primer Roll 120 (previously CM Primer) prior to the installation of the system.

Preparation of the Road Surface

• The areas to which the system is to be applied shall be clearly defined and marked by the Purchaser prior to commencement of work on-site.
• Any imperfections in the road surface not acceptable to the Installer shall be reinstated with a material approved by the Purchaser in consultation with the Installer.
• The road surface shall be clean, dry and free from ice, frost, loose aggregate, oil, grease, road salt and other loose matter that may impair the adhesion of the system.
• Where the road surface does not comply with the above it shall be cleaned by the Installer or others, by grit blasting, high pressure water jetting, low pressure water/abrasive blast cleaning, scarifying, scabbling or other means approved by the Purchaser. To remove dust and other loose matter the road surface should be vigorously brushed or treated with hot compressed air. Any oil visible on the road surface shall be removed by washing and scrubbing with a suitable detergent solution followed by flushing with clean water or by other suitable means.
• Existing road markings, ironwork, road edges of area to be treated and road studs shall be suitably masked.
• On concrete substrates, Swarcoplast Primer Roll 120 (previously CM Primer) shall be applied using a short pile paint roller or serrated edge squeegee at a typical coverage rate of 0.4kg/m², depending on the substrate texture and porosity. The road surface temperature shall be between 0 and 40°C. The Swarcoplast Primer Roll 120 (previously CM Primer) needs to be catalysed according to the following table:

Weather Conditions

• Installation of the system shall only be carried out with a road surface temperature of 0°C to 40°C and with a relative humidity of ≤85%. At temperatures below 5⁰C, the pails should be warmed to above 5⁰C.
• Ambient and road surface temperatures shall be recorded at the start and, if the weather is variable, during the installation process.
• Road surfaces shall be dry before and during the installation of the system.
• The curing period for the prevailing weather conditions shall be notified to the Purchaser.

Installation

System Installation Procedure

• PumaBrite road marking systems are available for use at substrate temperatures from 0°C to 40°C.
• PumaBrite containers should be kept out of direct sunlight during storage and use. Storage at elevated temperatures can lead to degradation of the system. Application of hot PumaBrite material can lead to premature gelling or curing, which can adversely affect product performance.
• PumaBrite Screed Road Marking System is a two-component cold applied chemically curing Methyl Methacrylate compound, consisting of a pre- accelerated base resin, blended fillers, pigment(s), aggregate, trace amounts of property modifying additives and a powder catalyst (BPO), supplied in pre- weighed quantities ready for on-site mixing. For the amount of BPO powder catalyst required for the installation temperature, see the following table:

Catalyst Addition Levels when using PumaBrite

• The catalyst level is critical – the minimum catalyst level is 0.5% (100g per 20kg pail or 50g per 10kg pail). Using less catalyst will cause partial curing and lead to product failure. Excessive levels of catalyst can lead to premature gelling and curing, which can lead to reduced adhesion to the substrate and product failure.
• Immediately prior to use, stir the pail thoroughly using a mechanical mixer until the resin is fully mixed. Add the correct amount of BPO powder catalyst and mix thoroughly for at least 30 seconds. Ensure that the binder at the bottom and sides of the container is completely mixed in. Do not delay once the catalyst has been added, as a chemical reaction is occurring that if left in the pail will ruin the mix.
• The mixed binder shall then be screeded onto the dry prepared road surface uniformly with a clean screed box at the required thickness, which will vary according to the texture and porosity of the road surface. The typical thickness is between 1.5mm - 2.0mm, but other thickness may be required.
• For lines requiring retro-reflectivity, suitable glass beads should be broadcast onto the material immediately upon application, before the product starts to gel or cure.
• If there is any delay to the work, the screed box must be checked before any work restarts to ensure that no cured material is left on the screed box, which could lead to a lower thickness of marking, and thus reduced durability.
• On more open textured surfaces a greater material usage may be required to ensure adequate coverage of the surface.
• Any masking tape used shall be removed as the work progresses, before the binder begins to gel or cure.

System Installation Checks by the Installer

• A visual check shall be carried out for uniform surface texture, blemishes, and any discernible faults.
• A check shall be made on completion of each site to determine the quantities of material used.

Maintenance and Repair

• In the event that damage occurs during the installation or during service the system shall be repaired as follows:
• The damaged and or de-bonded system shall be cut back to firmly adhering material, squaring off the area to be reinstated.
• The area to be repaired shall be cleaned, dried and the perimeter masked, allowing a 50 mm overlap on the existing well adhered system.
• The system shall then be applied in accordance with the system installation procedure.

Aftercare

• Any remaining masking shall be removed and the system allowed to fully cure. During the curing period, no disturbance or trafficking of the system shall be permitted.
