Beecks have manufactured mineral silicate paints for over 120 years. The range is comprehensive and unsurpassed in terms of lightfastness, vapour permeability and durability. Suitable for historic and contemporary buildings.
Renosil is designed as an economic, highly UV-resistant, colour stable, renovation paint which mineralizes the surface of synthetic resin treated facades.
It is for use onto synthetic paint coatings, artificial resin plasters, and is also ideal as a finish onto ecoCork render.
It has a matt mineral finish, it reduces the tendency for the surface to pick up dirt and it reduces the risk of algae, lichen and moss growth.
The main selling point for the Renosil is its application onto synthetic surfaces with a matt finish where you just apply one coat of course (thinned with up to 10% water) and one coat of fine (thinned with a maximum of 5% water). This makes it a simple system to use without the other stages/products.
PLEASE NOTE: Call us on 01874 611350 to discuss alternative colours as we have hundreds of recipes to match most colours. Available in more than 300 non-fading mineral colour tones. Can be toned in any ratio with BEECK FULL COLOUR SILICATE PAINTS.

- Application Advice
Whilst application for the BEECK system is by standard methods, these materials are more demanding than conventional masonry paints, it is therefore important that the person/s carrying out the work are familiar with the principles along with some ground rules to ensure long lasting results.
1st Coat: Beeck Etching Fluid - This is an acid concentration for removing the sinterskin (the fine film/coating from the binder paste on new renders following their rubbing up; lime or cement) from new mineral based renders.The application of the Etching Fluid is very important as it does just that, it etches the surface exposing the silicates available from the aggregates used in the render, providing a more active surface for the binder(potassium silicate) to react with the Beeckosil Finish.
Processing and Application - The Etching Fluid needs to be thinned with 3 to 5 parts water, depending on the surface to be treated, applied either by brush or a spray application, once applied it should be worked into the surface using a hard brush to ensure penetration. Following application the surface will effervesce (fizz) with the acid reacting with any calcareous material in the render, the maximum exposure time should be no more than 20 minutes, it should then be rinsed off thoroughly using a hose to rinse down the surface. Following the washing process the run off is completely inert and does not require any special considerations regarding disposal, as the Etching Fluid is inert and biodegradable. However, the Etching Fluid itself is an acidic solution of fluorosilicates in water, and Personal Protective Equipment (PPE) should always be used, and prior to use we would advise the user to refer to the manufacturers safety data sheet.
2nd Coat: Beeck Fixative - Fixative may be used as binder, thinner and primer, produced from the pure potash waterglass, it can sometimes be appropriate for solidifying crumbly, sanding mineral building materials, however, we would advise that you seek further advice prior to this use. In its function here as the 2nd coat it is a primer, used to equalize the surface to ensure a more even and uniform application of the Beeckosil Finish.
Processing and Application - Fixative should be thinned with 2 parts water and should be applied liberally to saturation ensuring as even coverage as possible leveling out any excess primer.
3rd and 4th Coat Beeckosil - Beeckosil is the decorative topcoat, a sophisticated formula yielding a Silicification-active, water- repellent, pure waterglass based, one-component mineral paint. Upon opening carefully stir the contents ensuring the liquid (waterglass) on the surface is thoroughly mixed back in. The manufacturer advises thin the base coat with 10 to 20% BEECK FIXATIVE, as any more renders the paint too thin making application very messy. For the topcoat thin to a maximum of 5% with Fixative. Apply crosswise sparingly, evenly and lap-free with a soft mineral paintbrush, a lambskin roller; spray gun application is possible but please consult us for further advice on this method of application. The most important advice we offer would be to treat adjacent surfaces at the same time, so that you maintain a wet edge and avoid dry seams. Where this is unavoidable find a suitable point or feature on the facade and finish to the best line, when the work proceeds this edge should be “cut in”, it is important to avoid any lapping with the existing paint at the dry edge as this may result in a clearly visible difference in the finish. Remember these coatings act more as a stain and are readily absorbed into the substrate and such lapping of wet to dry could lead to a visibly different concentration of pigmentation.
BEECK Mineral Paints have been around for more than 100 years, they are technically superb coatings in terms of:
- your health,
- the environment,
- and building protection,
They are not ‘Paints’ in the modern context and as a true mineral paint are only suited to a render that has not yet been painted.
They are mineral based coatings formulated with a binder of potassium silicate (waterglass), with inorganic, alkaline-resistant pigments.
They are fully inorganic (containing no organic solvents), non-offgassing, also being alkaline they inhibit microbiotic growth.
Mineral paints offer superior quality to conventional masonry paint as they petrify; binding to any silicates within the substrate, forming a micro-crystalline structure which provides a truly breathable finish.
In essence they are more a stain, that is chemically bonded to the substrate forming strong silica bonds in a process known as silicification, unlike conventional masonry paints which form a film on the surface of the wall.
