Finishing Render by Secil, is a lime-based premixed fine top coat render and renovation plaster.
Finishing Render is a blend of natural hydraulic lime and carefully selected aggregates.

Use as a top coat in the renovation and rehabilitation of exteriors on old masonry and as the designated finish for the ecoCORK insulated render system.

You can also use Secil Finishing Render as a lime filler for repairing cracks and damage on external lime renders.

Use on old or young rendered surfaces as a finishing layer in conservation and renovation. The use of natural lime binders, and their special composition, results in an excellent physical chemical behavior and mechanical performance.

Its thixotropic adhesion and permeability properties means it is particularly suitable for use over old rendered substrates.
Dry bagged product – just add water.

Coverage: 25 kg bag of Secil Finishing Render covers 4 m² at 4 mm thick (applied in two coats of 2 mm thick each).

Preparing the substrates

The subtrates must be clean of dust, sand, release agents, disaggregated or unstable
materials or paints. It is recommended, on old subtrates, to wash surfaces with pressurized water or brushing with a wire brush.

Preparing the mortar

The NHL Finishing Mortar must be mixed with the appopriate amount of water, in small quantities and using an electrical drill, in order to obtain a uniform paste without lumps.


After mixing the NHL Finishing Mortar, a smooth layer must be applied over the substrate. One or two layers of this mortar are enough to give the surface a smooth texture with a natural colour.

In the application process, the necessary cautions must be ensured, using the adequate techniques, in order to guarantee a continuous and uniform appearance, eliminating creases or other imperfections.

The total tickness of the coating should not be above 4 mm.

Additional Advice

The NHL Finishing Mortar must not be applied at temperatures below 5 ºC and above 30 ºC. In dry weather or under exposure to strong winds, proceed with the watering of the executed surfaces for a week, in order to keep the mortar permanently moistened.
