USING CONTROLL® INNERSEAL ON EXPOSED AREAS

WATER

Water penetration is among the major problem makers when it comes to concrete. Water transports subversive substances like chlorine and acids through the concrete, and therefore push valuable elements like calcium out of the concrete. (Calcium works like glue.) Water also accelerates frost dispersal and corrosion on re-inforcement armour. Controll® Innerseal fills up pores and prevents water to pass and thereby the problem to arise or aggravate.

CARBONISATION AND RUST

Carbon dioxide (CO2) penetrates, responds to water and breaks down the concrete. The pH-value is reduced in this process. Healthy concrete contains a pH-value of approximately 13. If the value sinks to under 9,2 it will provoke a corrosion attack on re-inforcement armour, which will swell and cause cracks. Controll® Innerseal prevents both carbonisation and rust.

FROST

When there is damage and dissolution on concrete surface caused by frost, you will find the source in water expanding in-side the concrete pores and pockets. When water freezes it dilates approximately 9 %, which is more stress than most concrete can handle. The same stress increases when water freezes and melts over and over again. If you also salt is added, the demanded volume is doubled. The result is further damage, dis-solution and cracks. Because Controll® Innerseal fills pores and pockets water penetration is stopped. Ice covers the concrete surface and therefore prevents damage inside the concrete.

CRACKS

Small cracks in concrete are highly exposed to problems, both chemically and mechanically. Controll® Innerseal works effectively with appearances of fissure up to 2 millimetre. Larger cracks is to be treated with proper expertise and immediately added Controll® Innerseal.

SALT FLUSHING

Salt flushing (efflorescence) is a crystal deposit formation on concrete surfaces. These deposits are water dissolvable salts that are transported in the concrete capillary system (see picture main page), and can wander in any direction. When these salts arise to the surface, the water evaporates and leaves behind disfigured white spots. The more porous the concrete, the better the transportation of these salts. By blocking the capillary system with Controll® Innerseal, the problem is effectively terminated. Controll® Innerseal stops water penetration and salt flushing, also in maritime environments.

ALKALI – SHIRT DEFINITION

Alkali is a combination of several ele-ments (hydrogen, lithium, sodium, potassium, rubidium, and caesium). These substances are all eager to react with other elements, especially sodium and potassium. You find them both in the crust of the earth (sodium 2,5 % – potassium 2,6 %). However, since they are always in combination with other elements they are hard to spot. None of these elements can appear separately in ear and moist. Alkalis are re-solvable in water, unstable and form salts

ALKALI PROBLEMS WITH CONCRETE

Concrete that is in direct contact with soil make it even more important to understand the connection between alkali and moist, and thereby also understand why problems with paint, cracks, „white spots“, smell, mould, etc. develops. ”The Alkali problem“ is primarily a moist issue.

Alkali is present in all concrete, but will not show evidence of damage without contact with water. If the concrete is in direct contact with soil or any other exposure to moisture, and there is not efficient ventilation to dry the concrete, moist is brought through the concrete by the capillary system.

Moisture develops alkali problems on the way and also brings them to the surface. It crystallises and presents self like desquamation and salt flushes. Even though the level of moisture and alkali is variable, there are enough moisture in soil and air for the alkali to react. Even concrete that seems dry has shown to store moist underneath paint and covers. You can often spot this as air pockets, desquamation and watermarks by visual inspection.

ACIDIC RAIN

Airborne pollution is one of the largest sources of deterioration on concrete. Sulphuric dioxide in the air is adapted in rainwater and creates sulphuric acid. The sulphuric acid re-acts with calcium ingredients in the concrete and is trans-formed into Calcium sulphate, which develops a thin pellicle on the concrete surface. Behind this film calcium sulphate is crystallising, pulverising the concrete and causes pealing and „depressions“. Controll® Innerseal fills pores and pockets in concrete and prevents acidic rain to penetrate.

PAINT

There are several reasons for bad paint quality on concrete:

Immediate addition of water/moist before, during and after painting is the most common reason. The concrete may be wet on the in-side, even if it seems dry on the outside.
The surface appears soft and loose. This cre-ates a surface quality that will reject all types of paint.
Poor preparation. There can be traces of oil, pollution (traffic film), paint wax, salt and moist.
The surface is too slippery to give hold for paint.

Our experience is that it is mainly moisture on its way out of the concrete that causes problems. The moisture brings along alkali and calcium to the surface and creates a reaction to paint adhesion, causes cracks, bubbles and desquamation.

Oil and acrylic paint is not made to penetrate and seal within concrete in the same manor as Controll® Innerseal. The best result will be achieved only when paint is used as topcoat after applying Controll® Innerseal. The product is a splendid connection for all types of further surface treatment.
