bonding agents for plaster and concrete

BONDING AGENTS FOR PLASTER, CONCRETE, AND GYPSUM

Bonding agents are crucial in ensuring the strength and durability of plaster, concrete, and gypsum applications.

Additionally, these agents act as a bridge between the substrate and the material being applied, creating a strong adhesion and preventing delamination or failure over time.

Furthermore, Sunanda Global's bonding agents can be used for interior and exterior applications. This versatility is essential for various construction projects, ranging from residential homes to commercial buildings, where different substrates and environmental conditions are encountered.

Bonding agents ensure strong adhesion and long-lasting performance in plaster, concrete, and gypsum applications.

By effectively bonding the materials to the substrate, these agents minimize the risk of failure, improve structural integrity, and contribute to the overall quality of the finished product.

Therefore, whether achieving a smooth and robust plaster finish, enhancing the bond between concrete surfaces, or optimizing gypsum-based systems, utilizing the appropriate bonding agent is essential for successful construction projects.

Bonding Agents for Plaster

For plaster applications, bonding agents are essential to improve the bond between the substrate and the plaster layer. Furthermore, they enhance the plaster's ability to adhere to surfaces, minimizing the risk of cracking or detachment. By promoting a secure bond, these agents contribute to plastered surfaces' longevity and structural integrity.

Bonding Agents for Concrete

In the realm of concrete, bonding agents are equally important. Specifically formulated to enhance the adhesion between new and existing concrete surfaces, these agents can bond fresh concrete to hardened concrete, ensuring a seamless transition and preventing the formation of weak points or joints. Additionally, bonding agents enhance the bond strength when applying overlays or repairs on existing concrete structures, resulting in a more robust and reliable outcome.

POLYALK EP AS POLYMER CEMENT BONDING COAT (PCBC)

  • Take 0.5 part fresh cement, 1 part POLYALK EP (by weight)
  • Mix thoroughly, preferably using a mechanical mixer
  • A slurry of a consistency easily applicable by brush is ready for use as a bonding material
  • In special cases, this composition may be modified by consulting CMCD
  • Clean the surface on which the bonding coat is to be applied
  • Clean it with a water jet approximately 24 hrs before application
  • Apply the bonding coat on the cleaned RCC surface by brush, taking care to avoid pinholes
  • Place the next screed or mortar, etc., that is to come over its wet on wet application

POLYMER-MODIFIED CEMENT MORTAR

  • Take 1 kg POLYALK EP, 5 kg fresh Cement, and 15 kg Quartz sand (graded)
  • (Polymer: Cement: Quartz Sand) Ratio is 1:5:15
  • This is a globally recommended composition
  • However, the proportion can be modified based on the consultant’s recommendations
  • First, dry mix the cement and graded sand in a mixer
  • Mix POLYALK EP with the premixed cement sand in the mixer
  • Mix for at least 3 minutes
  • A mechanical mixer with a specially designed stirrer may be conveniently used
  • Add a requisite quantity of water to attain dough-like consistency so that it can be hand-packed
  • The mortar is now ready for use

POLYALK EP AS POLYMER RICH CEMENT MORTAR (PRCM)

  • Take 2 kg POLYALK EP, 5 kg fresh cement, and 15 kg graded quartz sand. (i.e., in the ratio of 2:5:15)
  • Mix the three ingredients (without water), preferably in a mechanical mixer
  • Mix it till a soft mix of uniform consistency is formed
  • A blend with this proportion has the required strength and flexibility suitable for filling cracks effectively

POLYALK EP AS POLYMER CEMENT GROUT (PCG)

  • Take 1 kg POLYALK EP, 3 kg fresh cement, and 2 kg water (i.e., in the ratio of 1:3:2)

Bonding Agents for Gypsum

Moreover, gypsum-based applications, such as gypsum plasters or gypsum boards, also benefit from bonding agents. These agents provide an effective means of promoting adhesion between the gypsum material and diverse substrates. Furthermore, these bonding agents enhance the bond strength, reduce the likelihood of cracks, and improve the overall performance of gypsum-based systems. Whether it's plastering walls, constructing drywall partitions, or creating decorative gypsum finishes, bonding agents contribute to the integrity and longevity of the application.
