Equus-Chevaline Coverflexx NF High build flexible exterior bodycoat

By  Last updated: 7th November 2010

Chevaline Coverflexx NF
High build flexible exterior bodycoat

Application Properties:
Spreading rate:
1) As an encapsulant – 2-3 sqm/litre
2) As multicoat membrane without reinforcement – 1 sqm/
litre total.
3) As multicoat membrane, with reinforcement – 0.6-0.8
sqm/litre
Do not spread Coverflexx NF at more than 3.5 sqm/litre, as
this gives the minimum film build required to ensure effectiveness
of elastomeric properties.
Dry time:
Touch dry 2-3 hours
Through dry 12-24 hours
Full hardness 7-10 days
Under normal conditions (23º and 70% RH)
Maintenance:
When Coverflexx NF is used in an exposed situation topcoats
should be checked for re-coating on a 7-10 year cycle for
exterior use and a 10 year cycle for interior use. Clean when
required using low-pressure spray and a dilute neutral detergent
solution (cold or warm NOT hot).
If topcoats are renewed whilst film is still sound, the life of the
system will be easily prolonged for further similar cycle periods.
Health And Safety:
Coverflexx NF is a waterborne material and contains no
mammalian toxic substances. It is non-flammable and requires
no special storage conditions other than protection from frost or
high continuous heat. We recommend the use of barrier cream
on hands and safety glasses when handling or applying this
material. This is a low-odour product which can be safely used
in confined space or in the presence of other trades.
Purpose & Areas Of Use:
A high-build elastomeric membrane for use in exterior situations
as an encapsulant, particularly for asbestos containing materials,
and as a waterproof membrane under tiled surfaces in
ponded situations.
Product:
A flexible elastomeric waterborne high solids acrylic material
with high adhesion and water resistant properties. Has low dirt
pick-up properties when used in external applications.
Process Compatibility:
Use over Epistixx, Chevaprime AE, Coverall or Chevaprime-
U priming systems, depending on surface and in-service
conditions. May be overcoated with Colourglaze or Traxx 2000
Wearcoat as required.
