Tor Unicover W

Tor Unicover W (RC430) As a single product refurbishment coating for many types of building substrate, eg. Pre-coated cladding (Plastisol), Metal, Timber, Plastic (uPVC), masonry, concrete and most previously painted surfaces. A water based single pack primer/finish containing inert pigments and extenders, and acrylic polymers. Mould & Algae resistant* (see Limitations for details).

• Durable, long lasting system
• Multi surface application
• Available in 4,800+ colours, inc. RAL, RAL Design & Effect, BS, NCS & NCS 2050 colours
• Self-priming system

NB: Significant colour changes will require at least 2 coats to achieve adequate coverage.

What does the system include?

1st and 2nd coat - Unicover W

What does it do?

Tor Unicover W has been developed for the fast and cost effective refurbishment of external vertical wall cladding and large internal projects. It allows re-colouring for corporate re-branding or change of ownership or simply extends the life cycle of the cladding. The product is made on the Tor ‘in can’ tinting scheme, which offers any RAL/BS/NCS shade as an option. A water-based and extremely surface tolerant coating, Unicover is ideal for application in the warmer seasons, and can be spray or roller applied.

Where can it be used?

Primarily designed for the refurbishment and redecoration of vertical cladding materials such as plastisol. However also suitable for UPVC, weathered bitumen, metals, galvanised surfaces, ceiling tiles, wood, concrete, masonry, brick and plasterboard. As building refurbishment is dependant wholly on condition, we recommend asking for a free site survey to assess your building. This service provides you with a full site specification for your project.

Can be used on: Retail Stores, Warehouses, Manufacturing units, Distribution Units, any Commercial / Retail / Industrial buildings which utilise architectural cladding.

Surface Preparation

Important: Inspect all elevations of the building - condition of (say) North and South facing cladding may differ considerably.

Ensure surfaces are sound, clean and dry before coating, and any existing coatings are sufficiently resilient for overcoating. Remove surface contaminants by detergent scrubbing or high pressure power washing. Remove any moss, lichen, algae etc using Torkill W Fungicidal Solution (DM405). Ensure any existing coatings are adhering firmly to the substrate. Remove any residual chalking (if present) by vigorous rubbing etc with a fine scouring pad (eg. "Scotchbrite), and any other surface leachates or residues (particularly on plasticised PVC coatings) by either vigorous wiping with Tor Standard Urethane Thinners (TH99) or vigorous scrubbing with strong alkali detergent (eg. Torstrip WDA10 Wash Down Agent (SS4200005)) followed by thorough rinsing. Note: Abrasion of PVDF coatings (other than around loose or corroded areas) with fine hard abrasives should be avoided as this may polish the surface and impair adhesion of subsequent coatings - white aluminium oxide (80 mesh or coarser) or other suitable hard sharp mineral abrasive paper recommended to roughen coatings.

Scrape back any loose or weakly bonded materials and prepare to a firm feathered edge, and abrade exposed metal to remove corrosion products and provide a mechanical "key". Spot prime all bare metal areas with Tor Elastaseal Z Metal Primer (RC145) as appropriate.

Method of Application

Brush or airless spray (can be roller applied to large flat panels etc). Stripe coat all vulnerable areas, (edge, panel ends, bolt heads, etc) and allow to dry overnight before main coat application. Apply two full coats as necessary. Ensure good coverage especially vulnerable areas.

Limitations

• Overcoating should be carried out within the timescale stated on the product data sheet to promote maximum intercoat adhesion and avoid film defects.
• Surfaces must be clean.
• Ensure application conditions are favourable, the air and surface temperature must be between 10⁰C - 32⁰C and relative humidity a maximum of 85% during application and cure. Do not apply if there is a likelihood of rain, frost, fog or condensation affecting the freshly applied paint before it has fully cured.
• Avoid painting in direct sunlight and maintain a “wet edge” to avoid lapping.
• Moisture content of wood should be less than 15%. An additional coat should be applied to horizontal surfaces – eg. window sills for added protection.
• Not intended for areas subject to prolonged standing water.
• Depending on existing surface colour or pigmentation of Unicover W finish, some colours may require an additional coat to give full opacity.
• This product may have limited durability in aggressive (eg. heavy chemical atmospheres, severe climatic changes) environments. Contact the Technical Department for advice on alternative systems.
