OVERVIEW
Terrabond A is an extremely versatile bonding agents for use with all cementitious materials, lime washes,
plasters, etc. 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/sealerTerrabond 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 surfacesFor 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 screedsFor 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.
Mix the mortar/screeds using a solution of 1 part
Terrabond A to 10 parts water. For thin-coat
mortar, a solution of 1:7 is recommended. - For tile fixingFor Tile fixing mortar, the addition of Terrabond A
will increase the flexibility and improve the
cohesive and adhesive properties of cementitious
tile mortars. When using a thick-bed tiling
method, mix the mortar adhesive using a solution
of one part Terrabond A to five parts water. With
thin-bed tiling methods a solution of 1:3 is
recommended. - For cement based paints/lime washesFor cement based paints/lime washes, the
addition of Terrabond A will increase flexibility
and resistance to moisture, saline encrustation
and dirt.
The resultant mixture will promote
greater adhesive capabilities, improve dispersion
and aid brushability. Mix the paints using a
solution of one part Terrabond A to 5-10 parts
water.
