A revolutionary new building system combining an organic, mineral-based binding agent with a mortar-based solution that produces a building product with a high impact surface that can be rendered in a range of finishes from smooth coat to textured.

CRUPE Finish uses an organic, mineral based binding agent which is combined with gypsum, cement and sand to create a thin-coat render.

CRUPE Finish delivers a monolithic structure with excellent strength as well as outstanding fire, thermal, high impact and acoustic qualities.

CRUPE Finish can be used in a variety of ways, as a stand-alone product applied to materials such as EPS panels or Perlite reinforced with a nylon mesh or combined with our CRUPE Protect for a very robust, crack resistant render for a complete through the wall solution. Because CRUPE Finish is made with an organic, mineral based solution the resulting building material is generally more environmentally and user friendly than traditional cement or gypsum based systems.

CRUPE Finish is suitable for both existing (renovation) and new buildings and has a very high adhesion rate to concrete, brick, masonry, concrete block, wood or light steel framing.

CRUPE Finish has a polypropylene fibre blended into the dry mix that gives it the ability to resist cracking, making for a very stable final finish coat.

The CRUPE Finish render is a high impact medium weight building material comprising of gypsum, cement, sand with stranded polymer fibres resulting in a volume to weight ratio of 1750kg/m3. With the polymer fibres blended into the Dry Mix for reinforcement, CRUPE Finish has a high resistance to surface cracking, is very stable upon curing and exhibits imperceptible shrinkage when applied under controlled.

The key benefits of CRUPE Protect:

  • Creates a Monolithic surface
  • Certified and Rated around the world

A REVOLUTIONARY NEW BUILDING SYSTEM

Read more about CRUPE Finish specifications

CRUPE Finish is a building material that is applied as the finishing coat onto a new or existing building in a single operation that provides a monolithic surface. CRUPE Finish is a render with excellent fire rating and high impact properties and also offers effective acoustic and thermal properties when combined with CRUPE Insultherm.

CRUPE Finish can be applied by hand or by using a render spray machine. The product can be applied to all types of surfaces, brick, fibre board, concrete, OSB board, etc. For best results for fire, thermal and acoustic performance CRUPE Finish is best applied in combination with CRUPE Protect Insultherm 500/600.

APPLICATION AREA

  • Finishing render coat to external walls
  • Applied as final render coat for internal walls and ceilings

PRODUCT PROPERTIES

An aqueous gypsum plaster base and cement composition mixed with water and CRUPE’s patented additive is sprayed as pumpable, relatively fluid composition or manually applied by hand trowel. The mixture has sufficient viscosity that it does not slump on contact permitting a vertical or overhead layer up to 15mm.

CRUPE Finish is supplied in 20kg or 25kg bags depending on the region. The product is made up of a unique blend of calcined gypsum, hydraulic cement and sand which is combined with our patented CRUPE additive in the correct weight ratio. The chemical reaction occurs when the composition is mixed with water.

Hardening of the mixture takes about 60 minutes. After hardening, CRUPE Finish is of a mechanical strength to provide a high impact render for either external or internal final coat.

CRUPE Finish will set and gain hardness in a different manner to all conventional cement renders. Newly applied render must not be allowed to dry out too quickly and must be allowed to fully dehydrate prior to placing paint on the surface. Therefore, in extremely hot weather conditions it may be necessary to protect the newly applied render from the sun and drying winds so that it does not dehydrate too rapidly. Spraying a mist of water over the material to assist the curing process is recommended in such conditions.

Paint: It is advised that acrylic paints not be used as they do not allow the wall to breath. Therefore, CRUPE recommend breathable paints which can be easily found at any quality paint provider or specialised paint manufacture. In some cases, you may wish to increase the speed of completion by adding colouring agent into the mix thus eliminating the need to paint the walls and creating an alabaster look for your wall.
