BNL7

Product Description

BNL7 is a new generation for making facades of brick, concrete, plaster, natural stone, and grout durably water-repellent. The product contains at least 7% active substance and penetrates the substrate excellently thanks to innovative technology and is extremely fast-acting.

BNL7 is extremely fast-acting and in most cases, the facade is water-repellent within a few hours of application. After treatment, BNL7 is invisible and offers particularly durable protection.

The masonry is moisture-resistant but vapor-permeable, thereby increasing the thermal insulation value. The product prevents the growth of algae and is resistant to alkalis and acids and is unaffected by UV radiation from the sun.

Note:
If the substrate has already been hydrophobized or stones or mortars with hydrophobic properties have been used, then a water-based hydrophobic agent should not be applied. Use BNL10 or BNL25 instead.

Effective, simple, and easy to use Instructions for use

1

The substrate must be free of contamination and defects that will adversely affect successful hydrophobing.

2

Ambient temperatures during application should be at least 7°C, up to max. 25°C.

3

Protect materials not to be treated with a suitable protective layer.

4

Wear liquid-tight gloves and safety goggles.

5

Apply the product in a flowing coat (not spraying) in a horizontal motion, working from top to bottom.

6

Protect the treated facade from rain for at least 5 hours. Wind and direct sunlight can also adversely affect the penetration depth.

FAQ

How do I prevent lime efflorescence from coming back?

The most effective way is to impregnate (hydrophobize) the facade after cleaning. This makes the surface water-repellent. This not only extends the result, but also protects the facade in the long term.

What is the consumption per m² of the BNL products?

  • For BNL 1, 5 and 7 approximately 1 litre per m² applies.
  • For BNL 10 approximately 0.7 litres per m² applies.

How does impregnating work?

Apply the impregnating agent (BNL5, BNL7 or BNL10) generously to the surface of the facade. It penetrates deeply into the stone or pointing and thereby forms a protective barrier. After application, the masonry is moisture-resistant but vapour-permeable.

How long is the guarantee after facade cleaning?

The guarantee after facade cleaning and impregnating depends on several factors, such as the condition of the facade and the correct application of the product. When everything is carried out correctly, our systems can provide 20 to even 40 years of protection.

Why should I choose hydrophobizing?

  • It extends the lifespan of the facade.
  • Preservation of appearance.
  • It protects the facade against dirt, algae and moss.
  • It protects against moisture and weather influences. This prevents mould formation and frost damage.
  • The thermal insulation value is increased.

Do you also offer facade cleaning?

Yes! We even recommend this on a regular basis. Because we have a large network of facade cleaning companies, cleaning companies and other companies active in impregnating facades and masonry in the Benelux/Europe, there is often a suitable party nearby that we can put you in contact with.

Can every facade material be hydrophobized?

Our BNL products can be used for most types of facade bricks. We always recommend testing on a trial area first. It is designed to make facades of brick, concrete, natural stone and plasterwork water-repellent. Not sure whether your type of facade is suitable? Feel free to contact us for free advice.

Are your products PFAS free?

Yes, within professional impregnating agents it has long been the standard not to use PFAS.

What is hydrophobizing (impregnating)?

Hydrophobizing, also known as impregnating, is the process of making a material water-repellent. This is done by applying a special coating or treatment, which prevents water from penetrating the stone or the pointing.
