Black Concrete Effect Plaster 14 kg, Fox Dekorator

Fox Dekorator Black Concrete is a black concrete effect plaster for interior walls: a decorative lime plaster, ready to use, that you trowel on in two layers and polish to a raw concrete look. It is coloured black with natural pigments, contains no cement and lets the wall breathe. It comes in a 14 kg tub and sits in the Fox Dekorator range at Renders World.

Where Black Concrete Effect Plaster Fits

The maker describes it as a modern, raw lime plaster for interiors that harmonises with metal, glass and raw wood. Atlas recommends this black concrete effect plaster for:

• residential buildings;
• public buildings, including schools and nurseries;
• shops, offices, service points and shopping centres;
• transport buildings.

It is declared for internal walls, ceilings, columns and partition walls. The finish is yours to set: light trowelling gives a smooth, matt surface, while repeated, firmer polishing with the trowel brings it up to a satin sheen. The odd scattered pit or pore is part of the look of concrete.

Fox also shows the finish with a gold tape line set into it to imitate rustication joints, the pattern on the tub.

Surfaces It Goes Over

Black concrete effect plaster goes over these substrates:

• cement-lime and cement plasters;
• concrete, cast on site or precast;
• unplastered walls of ceramic or silicate blocks, brick and aerated concrete;
• gypsum plasters, skims and fillers, and polymer skims and fillers;
• plasterboard and OSB;
• acrylic paint coatings.

The wall must be load-bearing, even and seasoned until air-dry. Clean off anything that would weaken the bond — dust, dirt, lime, oil, grease and old paint residue. New work needs time to season first:

Atlas calls for bonding primer wherever the surface is smooth or has low absorbency, and Fox's own product page primes every surface with it before the first layer. The shop stocks it as the Fox Bonding Primer 3 kg. Seasoning times assume about 20 °C and 55 % humidity; they run longer in colder or damper conditions.

Applying and Polishing the Black Finish

1. Plan and test — decide the order and method of the layers, and try the final effect on a small sample first.
2. Stir — the black mix comes wet and ready; stir it to an even consistency. A little water can be added if you prefer it softer.
3. First layer — apply it smooth with a stainless steel trowel, to the thickness of the grain, and let it dry completely: 12 to 24 hours, depending on the room.
4. Dampen — before the second layer, wet the whole decorated area lightly with water.
5. Second layer — apply the second black layer over the whole area and level it.
6. Polish — as it dries, smooth it with the edge of the trowel held flat. The pores close and the surface takes on its typical smoothness. Keep the trowel blade perfectly clean throughout.
7. Seal — coat the finished black concrete wall with Fox Dekorator Satyna decorative varnish or a hydrophobic varnish, such as Fox Dekorator Hydrophobic Varnish 1 l, using a soft brush or a flocked applicator in criss-cross strokes. One coat already strengthens the surface; in damp rooms use two coats of hydrophobic varnish, and a rougher finish may need more.

Wash the tools in water straight after work. The black mix may have a characteristic smell, which does not affect its quality.

Specification

Drying times assume about 23 °C and 55 % humidity; colder or damper rooms take longer. Consumption depends on the texture and absorbency of the wall, how it was prepared, the effect you are after, the hand doing the work, and the thickness and number of layers — the maker advises a trial on the real surface to check it.
