Consumption Rate

The exact consumption of waterproof concrete adhesive is influenced by various factors, including the type and location of use, surface roughness, ambient temperature, cement type, size and grading of the aggregate materials in the mix, and some other conditions. However, the common consumption rates for some of the most widely used applications are as follows:

  • Connecting old concrete to new: Approximately 1.5 kg of polymeric grout (250 grams of waterproof adhesive) per square meter.

  • Stone filler solution (30% to 50%): Depending on porosity, between 100 grams to 200 grams per square meter.

  • For stone tiling with a thickness of 2 mm, the consumption rate is 1 kg per square meter.

  • In cement plaster, approximately 800 grams is required per square meter for a 1 cm thickness.

  • For smoothing mortar with a thickness of 3 mm per square meter, the consumption rate is 300 grams.

  • A 50% solution with water is used to improve the characteristics of ceramic powder adhesive.

Application Method

Using waterproof concrete adhesive involves several important steps, each of which must be carried out carefully to ensure the optimal performance of the product. Below are the general steps for applying the waterproof concrete adhesive:

  1. Surface Preparation: First, the concrete surface must be thoroughly cleaned and dried. It is essential to remove any particles, grease, dust, and other contaminants from the concrete surface.

  2. Installing Anchor Pins (Optional): In some cases, it is recommended to install anchor pins in areas that can focus the adhesive flow, enhancing its efficiency.

  3. Mixing the Adhesive: Mix the waterproof concrete adhesive according to the manufacturer’s instructions to ensure a uniform and homogeneous solution.

  4. Applying the Adhesive: Use an appropriate method such as spraying or using sprayers or waterproofing machines to evenly spread the adhesive on the concrete surface. Make sure to compact it uniformly.

  5. Applying Additional Layers (Optional): If necessary, you can apply additional layers of the waterproof concrete adhesive to the surface, paying closer attention to covering any weak points.

  6. Covering Weak Spots: Pay special attention to areas that might be considered weak points in the waterproofing coverage and apply the adhesive carefully.

  7. Drying and Strengthening: After applying the adhesive, allow sufficient time for drying and strengthening under appropriate environmental conditions.

Technical and Execution Recommendations

  • The mortar or concrete surface must be clean and free from contaminants such as dust and grease.

  • Mix the concrete adhesive in a ratio of 1:1 to 1:2 with water and stir thoroughly. Then, using a brush, roller, or spray gun, apply the mixture to the surface, which should be previously wet and free from surface moisture.

  • Apply the mortar or concrete only when the surface is sticky or damp.

  • Typically, for coating surfaces, each liter of “Building Chemical Waterproof Concrete Adhesive” covers 6 to 8 square meters.

  • Clean all tools and equipment with water after finishing the work.

Additional Information

Waterproof concrete adhesive is a bonding material used to create a moisture barrier on concrete surfaces. The key features of this adhesive include resistance to water and moisture penetration, elasticity, mechanical strength, high adhesion properties, and resistance to chemicals. By using this adhesive, you can effectively protect your concrete surfaces from various factors. Additionally, it is recommended to follow the manufacturer’s instructions carefully and work under safe conditions in accordance with industry standards. This will ensure better performance and stronger protection for your concrete structures.
This product is manufactured in compliance with ASTM C1059, C1042, and C1440 standards.

Mechanism of Action

The Waterproof concrete adhesive is a product based on acrylic resin and nano materials, which can be mixed with any type of grout. After application, it creates a strong bond with the structure and also has excellent penetration on various surfaces.
This material is compatible with temperatures ranging from -75°C to +350°C, offering great resistance to detergents, UV radiation, and CO2 gases. It also prevents the infiltration and growth of moss, algae, and bacteria on the surface, easily withstanding both positive and negative water pressure.

This product is recognized as a versatile material in the sealing industry and, once applied, completely clears the surface. The unique chemical composition of this adhesive allows it to become a flexible, water-insoluble coating upon drying, acting as an effective waterproof barrier.
