Technical Information
Product Description

Vetobond AB432 is an acrylic polymer-based bonding agent and cement modifier designed to be used as a bonding aid, curing agent, and gauging liquid for cementitious systems. It is resistant to hydrolysis and can therefore be used for external applications. Vetobond AB432 is a milky liquid that first turns purple when first applied on concrete then becomes clear once it dries, it is applied directly from the bottle or pail to the concrete substrate by brush, roller, or spray.

  • Adhesive bond to concrete will always exceed the tensile strength of the host concrete.
  • Suitable for use on damp and dry concrete.
  • Environmentally friendly water-based odorless and non-flammable.
  • Resistant to hydrolysis, used externally and internally.
  • High mechanical properties allow thin section applications.
  • Excellent bond to concrete, masonry, stonework, plaster and cement boards.
  • Cost effective, suitable for use in MENA region conditions.
  • Non-redispersable, type II.

Application Information
Instructions for use

Application of Bonding Aid

Thoroughly soak the substrate with clean water with remove any excess before the commencement of the works. Scrub Vetobond AB432 into the substrate, avoid puddling, and remove any excess. Apply the repair mortar or topping whilst the primer is still tacky.

Mix Design

A suitable mix design for a patching repair mortar or render:

OPC: 50 kg
Sharp Sand#60: 150 kg
Vetobond AB432: 10 Liters
Water - Enough to give workable consistency


Cure the repair mortar or topping using Vetobond AB432 to prevent rapid loss of water. In severe drying conditions, additional curing methods may be necessary. Protect uncured mortar from frost and rain.


Remove Vetobond AB432 from tools, equipment, and mixers with clean water immediately after use. Cured material can only be removed mechanically.

Surface Preparation

Clean all surfaces and remove any dust, unsound material, plaster, oil, paint, grease, corrosion deposits, or algae. Roughen the surfaces, and remove any laitance and expose aggregate by light scabbling or grit-blasting.

Expose fully any corroded steel in the repair area and remove all loose scale and corrosion deposits. Clean the steel to bright condition paying particular attention to the back of the exposed steel bars. Grit-blasting is recommended for this process.


Vetobond AB432 mortars, toppings, and renders should not be used when the temperature is below 5°C and falling. Neither should they be exposed to moving water during application. Exposure to heavy rainfall before the final set may result in surface scour.

Additional Information
Health & Sefety

Cementitious mortars and slurries modified with Vetobond AB432 contain cement powders that release alkalies that can be harmful to the skin when mixed or become damp.

During use, avoid inhalation of dust and contact with skin and eyes. Wear suitable protective clothing, gloves, eye protection, and respiratory protective equipment. The use of barrier creams provides additional skin protection. In case of contact with skin, rinse with plenty of clean water, then cleanse with soap and water. In case of contact with the eye, rinse immediately with plenty of clean water and seek medical advice. If swallowed, seek medical attention immediately – do not induce vomiting.
