Terraco Terrabond A Bonding Agent

Overview

It can be used to pre-treat substrates as an adhesion-promoting agent and as a primer/ sealer for decorative coatings. Terrabond A is a highly concentrated and economical-to-use product, specifically developed for the most demanding situation. It increases the compressive, tensile and flexural strengths of mortars and reduces the water/ cement ratio.

Terrabond A can be used with confidence on all exterior and interior surfaces.

Properties

Terrabond A is a non-toxic, non-inflammable, acrylic resin.

Areas of Use

As a primer/sealer:

Terrabond A is used for pre-treatment of porous but firm surfaces of concrete, aerated concrete, plaster, screeds, as an adhesion promoting and sealing agent. Before application thoroughly clean and remove any loose particles from the
surface.

Apply a solution of one part Terrabond A to 2 to 5 parts water (depending on surface porosity), using a brush or roller.

Repairing Services:

For the repair of surfaces, Terrabond A is designed to simplify the standard repair procedures and to help form a strong bond between the new and old work. Prior to application of repair mortar, follow the preparation procedures as previously
outlined. For porous surfaces and repairs in excess of 5mm deep, mix the cement mortar using a solution of 1 part Terrabond A to 5 parts water. For mortars to be applied less than 5 mm thick use a 1:3 solution. For firm surfaces, a
solution of 1:10 is recommended.

For plasters and screeds:

For plasters and screeds the addition of Terrabond A increases adhesion, flexural strength and improves workability of sand/cement mixes to be applied on surfaces such as fairfaced or float finished concrete. Prior to application, preparation procedures should be followed.
