Lime Green Ready to use silicate render finish 20kg
Lime Green Silicate Render Finish is a ready to use decorative final coat render. Due to its silicate-mineral binder, Lime Green Silicate Render has the breathability of lime, whilst being highly flexible and weather resistant.
This waterglass based product maintains the breathability and flexibility of lime while giving a crisper, more uniform appearance. Available in a wide range of colours.
Packaged in 20kg tubs, ready to use in a wide range of colours.
Yeild; Approximately 2.8kg to cover 1m2. A tub will cover around 7m2 on a suitably flat background.
Certain colours carry a small supplement - see drop down menuPrice is per tub

Waterglass technology – durability through silicification
Lime Green Silicate Finish Render offers low water absorption yet high vapour exchange, combined with excellent durability. Additional attributes are absolute light fastness and resistance to Ultra Violet light.
An effective self-cleaning effect results in pure bright facades - even after many years - free from dirt and algae.
This is made possible by the chemical process of silicification; the liquid product reacts to become solid silica, permanently fused to the substrate. This results in a finish highly resistant to weathering, fire and Ultra Violet light. Lime Green Silicate Mineral render does not form a film that is “bonded” to the surface, but becomes part of the render through silicification – the chemical reaction between mineral substrates and potash waterglass in the Silicate Finish.
This contrasts with conventional coatings which form films, such as synthetic dispersion or silicone resin emulsion finishes. In these a resin dries and bonds the material to the surface with the pigments and fillers. This produces a far less porous coating and an impermeable film unsuitable for natural insulation systems and solid walled buildings where breathability is paramount.
These film-forming coatings tend to become brittle when weathered, cracking and eventually spalling - a sign of the lack of interaction with the substrate. For ecological and economic reasons, from the point of view of building physics and durability film forming coating systems should be avoided on the Warmshell system.
Apply directly to the substrate after it is fully set and dried, allowing at least 10 days or 1 day drying per mm of thickness in the backing coat before application, whichever is the greater. The backing coat is levelled and finished with a plasterer’s lattice plane once it is set, removing any high spots or shiny laitance.
Mixing and application
Carefully stir up the full tub using a mechanical whisk. Do not add anything to the tub, but mix containers with different batch numbers to ensure consistency. Apply with a stainless steel trowel at the minimum thickness possible while still fully covering the background. Work with a wet edge continuously across a full elevation, or until a natural stop line (e.g. a movement bead or a corner). Lime Green Silicate Render will need at least one worker per lift of scaffold to ensure simultaneous and uniform application. Finish with a stainless or plastic trowel, with a gentle motion to bring a consistent texture to the surface.
Weather and curing
Apply in temperatures between 8°C and 30°C (note this includes surface temperature. Render in direct sunlight can be substantially hotter than the air temperature). Do not apply in rain, strong wind or cold weather. Once applied protect from rain and rapid drying for 24 hours.
