Capillary moisture
Why should I prevent the water entering the masonry?

Because the water can also rise behind barrier plasters or sealing slurries upstairs.

What do you call the water in the wall, which is transported by the pores of the building material?

Capillary moisture

What can the capillary water do to my wall?

The capillary water moistens the masonry and could rise from the foundation area to the upper floors of the house.

What is to be considered in the wall condition?

The more porous the masonry, the more water can be transported per day up.

What is to be considered with the wall thickness?

The thicker the wall, the more water can be transported up.

Is simply a barrier plaster enough?

No, it even impedes evaporation and the water can rise so unhindered.

Can I repair my moisture damage with a restoration plaster?

No, the water can evaporate because the plasters have a larger pore volume due to the special additives, but it does not prevent the water from penetrating into the masonry and rising.

What does the capillary moisture do with my wall?

The penetrating water is always slightly acidic, as it always contains some carbonic acid. It dissolves small amounts of lime from the masonry mortar. From the water-insoluble limestone, becomes the carbonic acid water-soluble calcium bicarbonate. The capillaries then transport the lime water to the wall surface where the water evaporates. Since the calcium bicarbonate has existed only in water, the water-insoluble limestone forms on drying wall again. This will then remain as a white deposit on the wall.

Can I not sweep the debris off the wall or cellar floor?

Yes, but that does show that the wall is wet and in constant decline. The lime comes from the mortar in which it was used as a binder for the sand.

What happens if I just leave the wall like this?

It becomes more and more porous over the years and the larger pores increase water transport. As a result, more lime is dissolved and the water transport is further increased. An undesireable cycle.

How can I as a layman test the condition of the mortar?

Just use a fingernail or a toothpick to scratch some mortar out of joint. Should that succeed, action is needed

What should I consider if I want to plaster wet walls?

Provide adequate ventilation and air exchange first. Approximately 3-6 months and stop rising damp and crosswise-moisture.

How do I recognize pressurized water / backwater?

When the water flows out of the wall or puddles form in the basement. Mostly occurs when water has accumulated in the former excavation and water can flow through small channels, for example missing mortar through the wall.

Is capillary damage the same as a pressurized water damage?

No, these should be fundamentally differentiated. Whether the causes of puddles are condensation or pressurized water, they can be easily distinguished. Pressurized water occurs at specific points. It is not weather dependent. Condensation, on the other hand, only forms on warm and humid days. The wall is then completely affected.

Can capillary damage make my building uninhabitable?

Yes, it can even negatively affect your health. Eg by mold growth.

There is mold on my wall. What do I have to do?

Do not panic in the case of small spots. Our immune system copes well with low mold load. However, with real mold lawns you should take counter measures at short notice.

I discovered a dry rot in my half-timbered house?

The fungus requires more than 15% moisture for its growth, otherwise fungus does not grow. A hydrophobic sealing of its walls reduces the equilibrium moisture content to less than 2% down to 0.6%. however, in addition to hydrophobing, the brown rot fungus should be killed. If water penetrates the wall at another point, the fungus would begin to grow again immediately.

I hydrophobed my wall.Can it still breathe?

Yes, the wall retains its natural thermal insulation and you will not experience problems with condensation. The masonry is water-repellent impregnated without clogging or constricting the pores.

What are the most common causes of invading or rising damp?

Common causes of penetrating and rising damp are missing or broken horizontal and outside seals.

Why is 4Everdry-Perfect the right product for me?

Safe application from many years of experience and successful use in many objects. With clever craftsmanship, you can easily install yourself a capillary barrier against the rising damp or a surface barrier against existing crosswise-moisture from the ground. After the barrier has completely formed, the masonry becomes an impenetrable water barrier. The walls become permanently dry and there are new possibilities of using the space. Moldy smell, unpleasant indoor climate or mildew are a thing of the past. The first choice, even under the most difficult conditions, tried and tested over many years and effectively against rising damp and crosswise-moisture.

Do I have to mask my windows?

If you have outdoor blinds, it is enough to let them down but it is not necessary. If the windows are reasonably clean (no construction site sand), it is sufficient to wipe off the hydrophobing with a cloth. Otherwise the sand residue from construction can cause scratches. Positive side effect: You don’t need to clean the windows for the next few weeks, the windows would be nano coated with hydrophobing. For large windows, we recommend to cover the windows with painter foil.

Small seashells after impregnation on the glass. What to do?

No problem, that is dried 4Everdry-Perfect. Tip: Easy removal with a household cleaner.

Do I have to mask my windowsills?

No, you can simply impregnate with 4Everdry-Perfect.
*If you ONLY impregnate the window sills, you should keep a cardboard underneath so that there are no runners on the facade. If you do not do it, the runners will eventually become visible as the unimpregnated facade becomes dirty after a while.

Do I need a scaffold?

A ladder is enough for a normal house.

Do I have to clean the facade first?

No it does not matter, but it makes sense for the look.

Do I have to renew my mortar joints?

No, the material penetrates deep enough into the facade.

Can I grout / mend the facade after impregnation?

Yes, but then you need to apply primer to the places where you want to fix. As the facade is now water repellent, the mortar does not last and would fall out again and again. You should then subsequently re-impregnate the newly grouted areas with 4Everdry-Perfect in about 2-3 weeks.

How long do I have to wait for the re-joint?

2-3 weeks so that the joints are completely dried out (hydrogenated) otherwise they become sandy.

How do I determine if the facade paint is breathable?

For example, if throwing a glass of water on the wall is not creating a puddle on the floor, but the wall is absorbing it, then wall is breathable.

Can I waterproof dense material/paint?


How do I remove dense material/paint?

Sandblasting, shotblasting or with a paint stripper.

When do I have to paint my facade?

We recommend before the hydrophobing. We advise you to wash off painted facades beforehand and to impregnate them after drying.

Can my facade be wet?

No, it should not rain for 2 days to allow facade to dry.

May I impregnate when facade has frost?

Yes, as long as the facade was not wet before and the water in the wall is frozen. Otherwise the 4Everdry-Perfect can not be distributed.

What types of paint can I not hydrophobicize?

Eg latex paints.

Can my facade still breathe after impregnation?


Why does moisture penetrate my facade?

In the original dry state of the facade, the removal of the moisture in the room is ensured by the outer wall. The wind creates a suction on the facade. As a result, negative pressure pulls the moisture out of the rooms of the house through the capillaries of the outer wall to the outside. Due to rough weather conditions (rain, driving rain) moisture can heavly penetrate into the masonry preventing the evaporation phase. If it rains frequently, the absorbent masonry absorbs a lot of moisture and the evaporation phase is constantly interrupted. The moisture in the masonry continues to increase and migrates inwards. The building material pores are filled with water and the removal of the moisture in the room is no longer guaranteed.

What happens if I do not do anything about it?

This scenario can continue so far that the moisture continues to move inward. Over time, the wall is so soggy and the moisture hits the inside surface of the wall. This results in a poor indoor climate, high humidity, fertile condition for mold growth, health risks and damage to the original thermal insulation.

What can I do against my wet facade?

To prevent this described scenario, the wall needs to be impregnated. The highly breathable impregnating agent prevents moisture (rain, driving rain) from penetrating the masonry. The masonry remains permanently dry. The original state of the dry wall is restored and permanently significantly improved. Full use of the rooms, comfortable indoor climate conditions, recovery of thermal insulation, cost savings.
