Description.

Lime Green's Ultra lime plaster base coat is a lightweight insulating lime plaster base coat that is five to ten times thermally more efficient than other lime plasters. This makes it the perfect plastering base coat for building renovations, where it gives an additional insulation layer to internal walls and protects against salt damage.

As an insulating lime plaster, Ultra Lime Plaster is such an effective insulator because it contains an aggregate of hollow beads made from recycled glass, which can make up to 55% of its bulk. This replaces the sand conventionally used in standard commercial lime plasters, which means Ultra Lime Natural uses less energy to manufacture and is significantly lighter to transport, so cutting down on distribution costs and energy.

Also, because it is applied as a wet plaster, Ultra Lime Plaster acts as a ‘draught excluder' by plugging any small pores and gaps within the fabric of the wall, something that standard dry-lining cannot do to the same extent.

Ultra lime plaster base coat is applied to walls in the same way as conventional lime plasters. It has good ‘workability' and there are no complicated fixings or problems achieving the right depth of coat.

Key points :

Reduced heat loss through the wall

Enhanced resistance to salts

Fibre reinforced

Highly breathable

Builds out in thick layers

Mineral ingredients are guaranteed never to rot

Completely Mineral
One of the great advantages of lime plasters is that they are mineral, without containing anything which will disolve in water or rot, unlike gypsum and polymer plasters.  Ultra is over 99.5% mineral once it has set, which also means it has the best possible Fire Classification (Class A1).

Thermal Peformance
Ultra is the warmest lime plaster on the market: with no cement and a thermal conductivity of just K=0.11 (lab testing at 0% moisture) or k=0.178 (moisture corrected as per the British Standard) it can be an invisible upgrade to your thermal peformance while re-rendering.

    Application:

    Surface Preparation
    Remove dust, surface contaminants and loose or friable coatings. Apply Beeks Fungicide if necessary. On dense, smooth masonry
    backgrounds or high suction backgrounds apply Lime Green Natural Stipple for improved bond. Other primers are available for
    difficult substrates - contact us for further details.

    How to Mix
    Ultra can be mixed using a drum mixer, or in a tub using a plasterer’s paddle mixer. Mix with approximately 4 to 4.5 litres of clean
    water per bag; do not add anything else. Use eye protection and dust masks and avoid creating excessive dust.

    How to Apply
    Only use Ultra above 5℃ and below 30. Ultra should be applied to a straight, flat, dampened surface in a uniform thickness of between 10 and 30mm, make sure this coat is keyed. After 2 to 7 days and the coat has stiffened/hardened, but is still ‘green’ more
    coats may be added. Make sure that curing is carried out between each coat (see below).

    Careful consideration must be given to detailing of areas such as cills and drips, especially on sites exposed to high levels of wind and rain. We recommend the use of a reinforcement mesh (Lime Green 910 mesh) to be applied to the final coat of Ultra when
    Ultra is used externally.

    Each section of mesh should overlap the next by 100mm.

    Curing
    The prevention of drying out too quickly is the key to the success of the application. Lightly spray the Ultra in hot weather if it is drying out too quickly. In addition, protect from harsh weather conditions, for example, frosts, rain and direct sunlight. The use of damp hessian, fixed to the wall can slow down the drying-out process and provide protection from adverse weather conditions.

    Finishing Coats
    Suitable finishing coats are Lime Green Natural Finish, Lime Green Solo or Fine Stuff, applied once the Ultra has set. Finishing coats should be applied in a uniform 3 to 6 mm thick layer with a trowel.
