Beeck Sensil Application

The Beeck Internal Range

Beeck Mineral Paints – Breathable, Durable, Non Toxic and Environmentally Friendly

The Beeck internal paint range is fully vapour permeable, hard wearing, environmentally friendly and can be used on virtually any background with the correct primer. Suitable for both historic and modern buildings, Beeck paints can help regulate humidity, achieving a healthier internal climate as well as offering unsurpassed durability.

The internal range comprises of three paints:

Beeck Insil – Standard internal mineral paint, offering a good durability, high vapour permeability and a reasonable scrub resistance at cost effective pricing. Available in white, colour group 1 and 2.
Beeck Maxol – Maxol is a very flexible paint which can be painted onto most backgrounds including Gypsum without a primer. It offers an excellent scrub resistance and is able to support the entire range of Beeck colours, from white through to colour group 4.
Beeck Sensil – Silicification active so offers the highest scrub resistance of all Beeck internal paints and is designed to offer maximum durability and longevity. Sensil retains all of the benefits associated with Beeck paints, including full vapour permeability and is made from natural materials. Available in white, colour group 1 and 2.

General Application Guidelines

Mineral Paint can be brushed, rolled or spray applied. Please refer to the relevent product’s technical data sheet for sprayer requirements.

As Beeck paints are absorbed into the surface and form a chemical bond, the application may demand more care and attention than conventional paints or lime wash. It is important that when applying mineral paints, a wet edge is maintained during the application and any cutting in is carried out as you move across each section, as much as reasonably possible.

The principal reason for maintaining a wet edge is that the paint binds to the surface and the pigments align together. If a wet edge is not maintained, the overlapping of fresh and dried paint will be highlighted. A wet edge is advised for most paint applications, conventional or mineral based, and is good practice.

Maintenance and Upkeep

Due to their chemical bond and high durability the maintenance for a mineral paint is relatively simple. The coatings are resistant to washing (background dependant) and cleaning agents, they can be regularly cleaned and maintained with little hassle. When it comes to recoating a Beeck Mineral paint, a clean down of the surface and one coat of paint is all that is usually required.

(Bare lime plaster and bare mineral surfaces, such as limewash and brick/stone pointed with lime mortar)

Surface Preparation

Paint is only as good as the surface to which it’s applied. Prepare the wall, ensuring there is no dust or loose material present. Treat the wall with appropriate cleaning solutions (water, sugar soap etc.) if required.

Stage 1 – Primer Coat: Beeck Fixative

Fixative is the active component to all Beeck Mineral Paints, for this application the Fixative works as a primer and stabiliser for the substrate.

Thin 1 part Fixative with 2 parts water and apply onto substrate.

Allow this coat 12 hours to dry before continuing the system.

Stage 2 – Base Coat: Beeck Sensil

Sensil needs to be thinned with 5% neat Fixative, stirred well and then applied.

Leave the surface for a minimum of 12 hours before continuing the system.

Stage 3 – Top Coat: Beeck Sensil

The top coat has to be tinted to the same colour as the base coat and can be applied neat.

Surface Preparation

Paint is only as good as the surface to which it’s applied. Prepare the wall, ensuring there is no dust or loose material present. Treat the wall with appropriate cleaning solutions (water, sugar soap etc.) if required.

Stage 1 – Primer Coat: Beeck Gypsum Primer

Gypsum Primer is designed to achieve a chemical bond between the paint and substrate on surfaces that would not normally achieve a chemical bond.

Gypsum Primer should be tinted to the same colour as Sensil.

Leave the surface for a minimum of 12 hours before continuing the system.

Stage 2 – Top Coat: Beeck Sensil

Due to Sensil’s high opacity/hiding power it can be used as a one coat paint over Gypsum Primer.

The top coat has to be tinted to the same colour as the base coat and can be applied neat.
