Moisture has a destructive effect on building materials such as brick, concrete, stone and wood. The most effective way to protect structures outdoors or close to the ground is to apply a barrier agent between the water and the absorbent surface. Such funds are called water repellents. They reduce water absorption, block capillary suction of the foundation, protect building materials from precipitation and the destructive effect of wind, and increase frost resistance.

We have prepared a rating of the best water repellents based on product characteristics and customer reviews. A brief analysis of products from different price categories will help you choose the right tool for your specific job.

Rating: 4.9

NEOMID H2O-STOP 5l, concentrate, art.845014

In the first place in the rating is a product from Russia, providing protection against moisture penetration for up to 10 years. The water repellent is supplied in a 5 liter canister and needs to be diluted with water 1: 2, which gives 15 liters of the finished mixture. The product is suitable for processing natural stone, brick, aerated concrete, wood, plaster. Masters in the reviews share that it can be added to cement-sand compositions and plasters, which will increase their frost resistance. The product is actively used in the production of concrete and paving slabs. With this use, the water repellent should be 1.5-2% of the total mass of the material.

Our experts have added the water repellent to the rating due to its versatility. The tool is allowed to be applied both inside the dwelling and outside and it is completely safe for humans. Also, the waterproofing gives the surfaces self-washable properties. For example, when painting the foundation of a house or a fence, sand and dirt will stick to it less, and during rains, traces from them can be easily washed off, maintaining a clean appearance of the facade.

Advantages

  • one canister is enough for 75 m² to cover a tree;
  • from 5 liters of concentrate, 15 liters of the finished solution are obtained;
  • fits most materials;
  • service life up to 10 years;
  • retains vapor and gas permeability.

disadvantages

  • high price;
  • artificial stone must not be painted;
  • not suitable for clinker tiles;
  • achieves water-repellent effect in 48 hours.

Rating: 4.8

CERESIT CT 10 antifungal 1l, art.1060333

The second place in the rating belongs to another product manufactured in Russia, but using German technology. The water repellent is supplied ready-made and does not need to be diluted. It is designed to be applied over tile joints 7 days after grouting. The substance helps to close these areas from the penetration of water droplets and maintain the natural color of the surface. The product is designed for indoor and outdoor use. Buyers in the reviews share that when used in the bathroom, the seams really do not darken. The manufacturer promises this effect for up to 2 years, after which re-treatment is required. The product is applied with a thin brush, and it is recommended to cover the adjacent areas with masking tape, because the impregnation quickly hardens and is difficult to clean.

Our experts have included the water repellent in the rating, since it not only protects against moisture, but also actively fights against the appearance of fungus and mold. This is true in bathrooms and other rooms, where water often accumulates on the walls and floor. Another advantage of the product is the readiness time. The surface will not let moisture through 2-6 hours after application.

Advantages

  • the seams retain their color (do not darken);
  • suitable for work inside and outside;
  • environmentally friendly;
  • prevents the spread of mold;
  • resistance to rain appears after 2-6 hours.

disadvantages

  • high cost;
  • consumption per 1 m² is 200 ml;
  • not diluted with water;
  • there is a pungent odor;
  • difficult to wash off tiles (only need to be applied to seams).

N730 Silifirn (5 L)

Rating: 4.7

N730 Silifirn (5 L)

The third place in the rating is taken by the product from the manufacturer 'Pufas'. It is a high-quality water repellant suitable for application to plasters, bricks, natural stone, porous concrete. But to achieve the maximum effect, two layers are required, so the consumption will be about 800 ml per 1 m2 on a porous concrete surface or 300 ml / m2 on a stone (depending on absorbency). Buyers in the reviews inform that the product is easily applied with a brush, spray gun or roller. The water repellent is sold ready-made. If repairs are planned for a warmer season, then the product can be easily stored for up to 24 months. The treated surface is good at repelling dirt, but does not impart frost resistance.

We put the product in the top ranking due to two clear advantages: composition and color. This water repellent does not contain solvents, so its smell is not as pungent as that of other participants in the rating. It is also completely transparent (not white), so it will suit any building materials and will not affect the exterior.

Advantages

  • water-based and completely safe;
  • immediately ready for use;
  • keeps air exchange;
  • kept closed for up to 2 years;
  • completely colorless, therefore suitable for any design.

disadvantages

  • not divorced – more substance will be required for a large facade;
  • high price;
  • for use outside, two layers are required;
  • does not increase frost resistance.

Water repellent Remmers Funcosil WS

Rating: 4.6

Water repellent Remmers Funcosil WS

The fourth place in the rating is given to the German water repellent, produced in cans of 5 liters. The substance is not diluted and is immediately ready for use. The composition is designed for mineral building materials, brickwork and cladding, plasters, natural stone and concrete, molded limestone. Unlike the leader of this rating, the product is allowed to be used on clinker masonry, which buyers like in the reviews. Due to its dense structure, the product reduces heat loss on walls and floors. The product has been produced by a German company for more than 20 years, and during this time it has already been repeatedly tested in various operating conditions. Along with a reliable protection against moisture, the floor and walls retain the ability to pass steam.

Our experts liked the water repellent for its UV resistance. Even if the sun's rays directly shine on it, the painted surface will retain its properties. The liquid does not have a pungent smell, so it is more pleasant to work with it. Practice has shown that applying hydrophobic coatings to weathering-affected surfaces significantly refreshes their appearance.

Advantages

  • does not emit harmful substances;
  • there are no solvents in the composition;
  • does not collapse from direct sunlight;
  • maintains vapor permeability;
  • reduces heat loss.

disadvantages

  • high price;
  • consumption from 400 ml to 1.5 l, depending on the absorbency of the base;
  • it is not a concentrate, which increases the price for 1 m².

Tiprom “U” deep penetration 5 l

Rating: 4.5

Tiprom U deep penetration 5 l

In fifth place in the rating is a water repellent consisting of siloxanes and silanes placed in an organic solvent. The substance is suitable for aerated concrete, paving slabs, plaster and various types of bricks. Buyers in reviews report that when applied to paving slabs, the adhesion of ice to the surface decreases, as a result of which it is much more convenient to clean the paths. Due to the transparent composition, the appearance of the materials does not change. If you treat areas below ground level with the mixture, then the product completely blocks the capillary suction. When exposed to water, the surface will withstand a level of up to 120 mm.

We ranked this water repellent as the best in terms of penetration. The manufacturer claims that the substance is absorbed into the surface up to 3.5 cm (into brickwork). These properties provide deeper material protection and longer service life. The product should be paid attention to the owners of single buildings, which are well blown by winds and rain.

Advantages

  • can be operated at temperatures from -20 to +30 degrees;
  • prevents the appearance of efflorescence;
  • resistant to alkalis and acids;
  • waterproof indicator – 120 mm water column;
  • deep penetration into the structure of the material.

disadvantages
