NO MORE DAMP SBR Latex is a Styrene Butadiene Copolymer Latex which is specially modified to be compatible with cement based mixes (ordinary portland cement or high aluminium cement).
It may be incorporated into cementitious renders, screeds or patching mixes in order to improve adhesion and resistance against water, chemicals and abrasion.
TYPICAL USES
• Effluent tanks
• Dairies
• Food Factories
• Fertiliser stores
• After a damp-proof course due to it’s salt-inhibiting and waterproofing qualities
ADVANTAGES
CAN BE USED IN AREAS OF CONTINUOUS OR INTERMITTENT WATER CONTACT
IMPROVES FLEXIBILITY AND REDUCES CRACKING
IMPROVES RESISTANCE TO CHEMICALS AND ABRASION
IMPROVES ADHESION
IMPROVES WORKABILITY OF MIX TO ALLOW THINNER SCREED TO BE LAID
IMPARTS HIGH WATER AND SALT RESISTANCE WHEN ADDED TO MIX
ALLOWS A REDUCTION IN WATER CONTENT
SUBSTRATE PREPARATION
Where specific build methods are covered by British Standard Codes of Practice, i.e. rendering and floor screeds, these should be followed as a guide to good building practice.
All surfaces must be sound and free from laitience, paint, grease, oil, surface water or any other contaminant which may adversely affect adhesion. Surfaces of high suction
PROPERTIES:
should be thoroughly dampened before the application of bonding primers.
Remove excess water from the surface before continuing.
The sand to be used in the mixes should be well graded, clean and meet the appropriate British Standards.
Additional preparation is required where steel reinforcement is exposed.
Wire brush or preferably gritblast to remove rust and scale, apply Bonding Primer 2 liberally by brush to the prepared exposed steel and allow to become firm.
MIXING
BONDING PRIMER 1:
1 Part NO MORE DAMP SBR Latex: 1 Part Water : 5 Parts Cement (by Volume) mixed to produce a smooth, creamy consistency.
BONDING PRIMER 2:
1 Part NO MORE DAMP SBR Latex: 2 Parts Cement (by Volume) mixed to produce a think, smooth cream.
