santaneEFL and TL  

The santane range of coatings are elastomeric, polymer-based materials for the decoration of new and existing facades. The products form the basis of six refurbishment systems for the decoration and repair of existing facades.

• Resistant to cracking: up to 2mm (EFL)
• Supplied in a range of colours
• Supplied in smooth (EFL) and textured (TL) finishes
• Provides a durable weatherproof protection to the substrate
• Can be used to bridge movement joints using ancillary products
• Has anti-carbonation properties for the protection of reinforced concrete

santane EFL and TL are available in a range of 20 colours. Specifiers should consult the Colour Chart on page 31 of the specifiers' handbook weber render solutions and, whenever possible, obtain samples prior to specification.

Do not apply:
During very humid weather conditions or if rain is forecast
During extreme hot weather or when exposed to strong winds
On damp or frozen/thawing surfaces
On horizontal surfaces exposed to wet conditions
On friable coatings or coatings that have lost adhesion

Surfaces must be sound, flat, clean and dry. Existing coatings should be removed if deemed to be unstable and with poor bond. Existing coatings should also be removed if they are epoxy/ polyurethane or if the coating is greater than 300 μm when applying santane systems 2, 3, 4, 5 and 6.

Porous or friable substrates should be treated with a one coat application of weber SL410. This should be allowed to dry prior to the application of weber PR335.

Widen out cracks less than 1 mm to 5 mm by 5 mm deep with a disk cutter or sharp tool. There is no need to widen cracks greater than 1 mm. Cracks greater than 2 mm should be treated as movement joints.

Existing construction movement joints should be completely removed and a new joint formed. Details are available from weber's Technical Department on request.

Prime the whole surface with weber PR335.
Fill cracks with a suitable sealant.

If santane systems 5 or 6 are adopted, the substrate may need levelling to provide a flat surface for the final coating. This is likely to be the case for the refurbishment of mosaic tiles or brickwork for example. In order to level the surface apply renovex P in accordance with the relevant instructions.

Allow 2 - 3 days for the levelled surface to dry before priming for the final coatings.

Apply one coat of weber PR335 using a wool or foam roller and allow to dry for 24 hours prior to the application of the santane finish.

Incorporating mesh
Where the system specifies the incorporation of a mesh, apply one coat of santane EFL at the rate of 400 g/m2 and immediately incorporate the mesh using a roller or stainless steel trowel. Use mesh Ti for slightly uneven or irregular surfaces and mesh NT on smooth/flat surfaces. Mesh must cover at least 50 mm beyond the edges of all cracks and be completely encapsulated by the coating.

A second application of santane EFL should be carried out when the initial coat is dry.
The finish coat of either santane EFL or TL is applied when all intermediate coats are dry.

santane EFL
When the primer is dry, apply santane EFL in a crisscross manner. with a wool roller, and regulate the thickness of each coat.

Provide finish by passing a wool or foam roller gently over the final coat in a vertical manner, according to the finish required. The preceding coats (primer and intermediate coats) must be dry before applying the finish coat (usually 24 hours at 20°C and 65% RH).

The thickness of the dry film varies between 0.2 mm and 0.7 mm dependent on the system adopted.

Apply santane EFL at temperatures between 5°C and 35°C. Do not apply at a relative humidity over 80%.

santane TL
For system 1, apply santane TL to the primed substrate using a stainless steel trowel.

For systems 2, 3, 4, 5 and 6 apply santane TL to the primed surface over one or two applications of santane EFL.

The finish is achieved by using a plastic float rubbed in a circular action over the applied material.

The thickness of the dry film varies between 1.8 mm and 2.0 mm dependent on the system adopted.

Apply santane TL at temperatures between 5°C and 35°C. Do not apply at a relative humidity over 80%.

For roller application of santane EFL allow 250 - 400 g/m2 per coat for flat surfaces dependent on the system.

For santane TL allow 1500 g/m2 for flat surfaces.

Note: These estimates take no account of wastage and will vary according to the type of surface involved.

When stored airtight in a dry place at temperatures above 5°C and protected from frost, shelf life is 12 months from date of manufacture. Do not over-stack.
