Oppercon: application

What Oppercon does:

Oppercon is a surface treatment product, that coats the surface structure of the stone and concrete at the molecular level. It keeps the surface of these building-materials water-repellent and makes them algae and fungi free.

Water vapor permeability
Oppercon protects but does not seal off the surface. The material continues to “breathe” so the vapor permeability is maintained, proper water management is ensured in this way. Oppercon guarantees a longer aesthetic and practical durability of your building material and structures made ​​thereof.

Oppercon is UV-resistant, it will not discolour nor in any way have any discolouring effect on the treated surface. Oppercon also resists freeze thaw and salt damage.

Oppercon is very economical and durable.


How Oppercon works:

Oppercon will wrap itself in and on the surface structure at the molecular level. It forms a coating around each granular material, this up to a quarter inch deep. This guaranties that Oppercon will never flake, break, crack or become loose from the treated surface in any way.

Because of the very slow biodegradable properties of Oppercon (± 15 years) it will eventually disappear from the surface, this is an essential part of the environmentally friendly properties of this product. After about ten years, you can re-treat the surface with Oppercon, without first having to clean or sandblast the surface, which is very costly.


How to use Oppercon:

Oppercon is Applied with an low pressure sprayer. You can also use an ordinary hand spray bottle or larger pump for larger surfaces. If available is a professional high-pressure spray can also be used.

Before starting treatment, remove dirt, mold, algae and vegetation from the area to that you want to treat.

Apply Oppercon on a surface temperature between 41 °F and 77 ° F.
Shake Oppercon before using and apply evenly over the surface of the wood, without leaving any drops or runners.

In a porous or old worn surface, it may be necessary to apply a second layer. Apply the second layer before the first layer has dried.

Caution: Do not apply Oppercon on dried parts which have already been treated.

Suggestion: glass and frames need to be taped off and covered up. You can also soap them with a thick soap concentrated solution in advance, to prevent Oppercon from sticking to these materials.

  • Tools:
    Oppercon is applied with a low pressure sprayer. This can be done by both the ordinary plastic hand spray bottle for smaller surfaces or with the slightly more professional plastic cylinder with hand pump for larger surfaces. A professional high pressure sprayer, if available, can be used as well. They will all bring the same perfect result.
  • Temperature:
    Do not apply Oppercon to surfaces colder than 41 degrees Fahrenheit and not warmer than 77 degrees Fahrenheit. This to prevent Oppercon from freezing and prevent it from rapid evaporation of the water with is it’s catalyst.(In case of rapid evaporation of Oppercon, it cannot penetrate quickly enough, which can lead to white stains on the surface. When the surface is above 77 degrees Fahrenheit, apply a layer of regular water to cool down the surface. When dry you can apply Oppercon without any problem.)
    In case of rapid evaporation Oppercon cannot penetrate deep enough. It will then remain on the upper surface which may cause white and persistent encrustation.
  • Glass and adjacent materials:
    Oppercon will not damage or etch glass or other glossy materials It is possible though, that if you leave drops dry on these kind of materials persistent white stains can build up. We therefore recommend to remove these drops on time with a sponge and water before it dries up.
  • Application:
    Before applying Oppercon, remove all dirt and fungi from the surface. Then apply Oppercon evenly in a uniform pattern, without dripping. When the surface soaks it up easily, do it again before you move on. We recommend to cover up the parts that shouldn’t be treated. If this should occur by accident, you should remove the spillage immediately with water and an sponge.Shake Oppercon before use and do not apply on a moist surface.
    Tip: glass and frames need to be taped off and covered up. You can also soap them with a thick soap concentrated solution in advance, to prevent Oppercon from sticking to these materials.
  • Second application:
    In case that the surface is porous and old, it might be necessary to apply a second layer. This should be done before the first layer has dried up and hardened.
  • Important!
    During the application – Never go back to dried parts where Oppercon has been applied. Oppercon does not only stop water, but also stops itself once it is dry and hardened.


Use how much Oppercon:

1 liter Oppercon is sufficient for an average for 8 m2 (depending on the porosity and quality of the surface).


The difference between Oppercon, Permacon and Cementmix:

Oppercon is a surface treatment repellent agent for concrete, stone and stony materials.
Without leaving any visible trace of its presence, it will, unlike Permacon, make the surface of these materials waterproof, water repellent and UV-resistant. Because of its repellent properties, it means that a finish, like paint, cement or any kind of finish is not possible. The Oppercon treatment should be repeated after 15 years.

Permacon can be applied to any cementitious surface (concrete, stucco, concrete bricks, stone bricks, marble, gypsum or porous natural stone etc.). Its simplicity as for the application techniques, makes it most convenient for the treatment of walls, floors, ceilings and any structure made with these materials, in any form and size.

Permacon is very suitable under hydrostatic pressure for concrete ending up underneath the soil, like basements, foundations, sewage pipes, tunnels or with floor heating etc. after you’ve applied Permacon. Unlike Oppercon, which is a repellent agent, it’s possible to add a finish paint, cement or any kind of finish you wish. Guaranteeing a perfect, durable and waterproof surface.

Cementmix replaces water and makes all kinds of cement, concrete, self-leveling mortar etc., through-and-through water- and liquid proof. This applies to both the surface, as for the underlying layers. Any finish like paint, cement or any other kind, is not possible. The treatment is permanent.
