Beeck Maxil Pro Application

Maxil Pro Application guide, covering application onto vapour open backgrounds such as lime plaster and vapour closed backgrounds such as gypsum plaster.

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 Maxil Pro – Maxil Pro (formerly 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.

Beeck Maxil Pro

Maxil Pro onto Vapour Open Backgrounds

Vapour open backgrounds include 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 Maxil Pro

Maxil Pro needs to be thinned with 10 to 15% water, stirred well and then applied. Leave the surface for a minimum of 12 hours before continuing the system.

Stage 3 – Top Coat: Beeck Maxil Pro

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

Maxil Pro onto Bare Gypsum Plaster and Vapour Closed Backgrounds

Vapour closed backgrounds include any gypsum based and non-porous backgrounds such as cement and acrylic based paints)

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. If existing paint coatings are in poor condition a mineral based paint may be too strong for the background and we would suggest trying an alternative paint.

Stage 1 – Base Coat: Beeck Maxil Pro

Beeck Maxil Pro can be applied directly onto gypsum plaster and existing paint when it is in good condition, whilst still achieving its chemical bond.

Maxil Pro needs to be thinned with 10 to 15% water, stirred well and then applied.

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

If applying Maxil Pro directly onto plasterboards, or if there are any concerns about the suction of the plaster/painted background, please use Gypsum Primer as the base coat instead of Maxil Pro.

Stage 2 – Top Coat: Beeck Maxil Pro

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

  1. Hi im re pointing an internal stone wall with lime. My question is the stone is very dusty and will be cleaned but is there a breathable sealer that can be applied either before printing or after to bring colour back to the stone. The outside of the wall has been plastered using a breathable glass plaster. Also… terrible stonemason damaged the wall, we are now having to undo his damage and rake out and re point. He literally threw the line at the wall and now have to clean over 40sq M… any ideas on how to do it fast?
    Thanks
    Great advice on this page!

    1. Thank you for your enquiry. Etching Fluid can be used to clean lime, there is no perfect way to clean it as any cleaning can impact the colour of the stone but Etching would be the safest option.

      Fixative can be used as a stabiliser to help prevent dusting although test trials would need to be carried out as it depends on the stone. Sandstones for example don’t always work as they can have salts present, the salts can react with the Fixative and cause a scumming effect to be pulled through.

      Etching should be diluted at 4 water to 1 Etching, painted on and washed off after 20 mins – may need a few applications.
      Fixative as a stabiliser should be diluted 4 or 5 parts water to 1 Fixative and applied as a flow coat, basically this is continually applying the product until the wall can no longer take any more.

  2. Hi. I am looking for a solution to some internal walls that have white crystals on them and in places dark patches. I suspect that this is damp and due to having concrete floors the moisture is being trapped by the Dulux white paint on the wall currently.
    I have removed some of the paint (it cam off easily due to bubbling). The house is Victorian and the bricks very porous (no point in injecting damp chemicals) so I hope there is a paint / other solution out there which I can apply to the walls.
    The walls have been plastered using a modern gypsum plaster.

    Thanks in advance

    1. Thank you for getting in touch. The crystals are likely being caused by salts, salts can be present within the brickwork and are definitely present within the gypsum plaster. The issue here is that whilst a breathable paint will allow moisture to escape and hopefully eliminate damp spots, it wont prevent salts from coming through. Salts are soluble and can transfer through the plaster, crystalising on the surface and as there as salts within the plaster this will continue even with the correct paint.
      Ideally we would recommend removing the plaster, keeping the wall bare and allowing the wall time to dry. Then replastering with lime and using appropriate breathable paint. If you would like further information please don’t hesitate to contact us.

  3. Hi, I have had some lime plaster applied in my 1884 cavity-wall house about six months ago in areas where rising and penetrating damp has occurred. It seems to be working as regards permeability as there are currently no damp patches in the rising damp area, at least. Regarding cleaning the walls, they’re a little dusty and uneven. Any tips please? And them, With Maxil Pro, will I have to buy & apply the primer first or can it go straight onto the walls? And if I paint over some existing emulsion paint elsewhere in the house interior, will it be okay and help to prevent black mould? Many thanks.

    1. Thank you for your enquiry. The wall can be cleaned down with a stiff brush or a damp cloth.
      We would then advise using Beeck Fixative as a primer for bare lime plaster. This is designed to help control the absorbency of the background.
      For existing emulsion, providing the coating is in a good and stable condition, clean down the surface and apply the paint. The paint is alkaline and resistant to mould, however depending on the background and environment mould can be very hard to prevent. Please let us know if we can assist further.
