Vogue by JPS Coatings is the ideal concrete look exterior render mix for rigid masonry surfaces, such as rendered concrete and formwork, rendered brick and blockwork, and expanded polystyrene (EPS) cladding systems. The non-flexible cementitious blended polymer modified coating provides a superfine, subtly mottled finish for that concrete panel aesthetic.
1. Prepare the surface. The substrate must be completely dry, clean and free from oil, grease, dirt, dust, mould, release agents, and other contaminants that may be considered bondage breakers. Surfaces consisting of freshly applied cementitious renders must be left for a minimum of 28 days for the cement to fully cure. Allow more time during the winter.
2. Prepare Vogue. Using a mechanical stirrer, the applicator must mix Vogue with around 4.2 - 4.6L of clean, potable water for every 15kg bag. Continue mixing until a homogenous paste is achieved. The applicator must observe close caution not to use more water than the recommended dose as this may lead to excessive shrinkage. The mixture will be allowed to stand for five (5) minutes prior to re-mixing. It is advised that application not be carried out under full sun or hot and windy conditions.
3. Apply first coat of Vogue. The ideal application of Vogue is two (2) thin coats. The applicator must use a stainless steel trowel to apply the first coat to the rendered surface at a thickness of approximately 0.8 - 1mm. The concrete look exterior render mix must be spread to achieve a uniform and smooth coating, without leaving excessive trowel marks. The material will then be allowed to harden sufficiently so that it will not be sticky to touch.
4. Apply second coat of Vogue. The second coat of Vogue will be applied using the same stainless steel trowel at a thickness of around 0.8 - 1mm. Thereafter, the material must be allowed to harden until it is no longer sticky to touch, so that it feels slippery under the trowel. At this point, Vogue can be lightly polished with a wet steel trowel to achieve a flat finish. The applicator may aid the finishing process by using water to sparingly mist onto the surface. Care should be taken not to overwork the drying process or leave off sticky material. Overworking and excessive water can result in surface peeling. The thickness of the finished coating is ideally at an estimated 1.5mm.
