Surface preparation
Indoor and outdoor surfaces should be in conformity with the current standards in force. Surfaces must be homogeneously absorbent, sound, clean, dry, non-friable and deprived of salts, moisture and moulds.
MARBREX R lime plaster can be applied directly to natural lime plasters , preferably a fresco (wet on wet). When used a secco (after drying), dampen the wall with clean water, avoiding streaming before applying MARBREX R lime plaster
Concrete surfaces, cement, dusty lime plasters , gypsum, old compatible paint ( peeling paint and semi-gloss or gloss paints must be sanded or removed or primed with a water-based primer ) should be fixed beforehand using our SOUS COUCHE POUR CHAUX EXTRA lime primer . Plasterboards and other types of boards must be primed with a water-based primer before applying SOUS COUCHE POUR CHAUX EXTRA lime primer
For a rapid, economical and attractive finish on difficult or irregular surfaces, we recommend you use a mixture of (ratio 1/1) our MINERAL 000 lime plaster in powder form mixed with our eco friendly multi-function mortar MULTITOP . This will give a lime plaster finish which is that has excellent adherence and water resistance.
For other surfaces, contact us for technical support.
Application
Appropriate tools : stainless steel trowe l, sponge float . MARBREX R lime plaster may be projected.
Apply 1 or 2 coats of MARBREX R lime plaster , 2 to 3mm thick, depending on the finish you want. Do not go beyond 3mm thick per coat.
Delicately rustic surface ( one coat, sponge floated ): apply the lime plaster using the stainless steel trowel about 2 mm thick. When the plaster begins to harden, level off and bring out the grain using the sponge float by dampening the surface. Avoid excess water.
Rough stone look (two coats, burnished): apply to a first coat that is dry and sponge floated . Dampen if necessary and apply a second coat between 1 and 1.5mm thick. Sponge float and burnish using the stainless steel trowel before it dries.
Smoothed (matt stucco finish): before the first coat has dried, apply a second coat with the stainless steel trowel , 1 to 1.5mm thick. When the plaster begins to harden, use the edge of the stainless steel trowel to make the plaster shine. You can use our MINERAL 000 lime plaster in powder form for the first coat.
Interesting antique or multi-color effects can be created with natural pigments and our VELATURA glaze or using our BADIMAT ® lime wash paint over the MARBREX R lime plaster surface.
MARBREX R lime plaster should be used as the base for any of our stucco finishes ( Marmorino , Tadelakt , Mantovano …) used in combination with our MARBREX L , MARMOLAKT and FINITION S lime stuccos
Drying time - Carbonation
24 hrs to 48 hrs depending on the absorbency of the substrate and the ambient humidity.
Where humidity, condensation or water-vapor is present, efflorescence, whitening, variations in color and fading may occur on surfaces that are not totally carbonated. Protect the end result from any rain for several days. To accelerate carbonation after the lime plaster has thoroughly dried, we recommend that you spray the surface gently from bottom to top with clean water using a low pressure spray. Avoid any streaming. Repeat this several times, leaving time to dry in between each spraying.
Coverage
2 kg to 3 kg / m², depending on the surface and the desired end result.
Protection
To protect the surfaces from water and stains: you can waterproof using our HYDRO R water repellent (1 or 2 coats) and if you want a shine finish you can wax with our CIRE SOLIDE bees and carnauba wax (1 or 2 coats).
For outdoor work, waterproof with 1 or 2 coats of our HYDRO R water repellent
