SpECtite CW100 may be used where there is a
requirement to exclude water from a building or
retain it within a structure. The material is particularly effective where there is a requirement for crack
bridging capability, typically in the following situations:
• Potable water containers, tanks and reservoirs
• Swimming pools and silos
• Waterproofing planter boxes
• Waterproofing new and existing buildings
• As a backing to marble and granite to prevent
water ingress and thus alleviate surface staining
• Protection against brackish water
• Coating seawater channels
• Wet Areas, Toilets, Balconies & Loggia
• Withstands hydrostatic pressures
• Good bond strength to concrete and masonry
• Good crack bridging capabilities even after
long periods of immersion
• Long pot life even at high temperatures
Preparation
It is essential that adequate preparation is carried
out prior to the application of SpECtite CW100.
The substrate must be clean and completely free
from contaminants including grease, oil and loose
material. Any repairs to the substrate should be
carried out using SpECbuild cementitious repair
mortars.
Mixing
SpECtite CW100 is supplied as a two component
pack consisting of a liquid component and a powder
componentThe product cannot be mixed by hand.
The liquid should be poured
into a 25 litre plastic or
metal drum. The powder
should be added slowly
whilst mixing with a spiral
paddle attachment on a
slow speed electric drill.
Mixing should continue
until the product is lump free and for a minimum of
5 minutes.
Application
The prepared substrate should be dampened using a
fine water spray. Care should be taken with porous
substrates as more extensive pre-soaking will be
required. Any free water on the surface should be
removed immediately prior to applying SpECtite
CW100.
While the substrate is damp but free from standing
water, apply the mixed product a minimum of 2
coats by medium hard short bristle brush, trowel or
roller checking that the first coat is at a minimum
wet film thickness of no more than 1.5mm and no
less than 0.5mm. The product should always be finished in one direction.
The second coat should be applied as soon as the
first coat is set hard, normally after a minimum of 3
hours @ 25°C and longer at lower temperatures.
This second coat should again be finished in one
direction (at 90° to the first coat).
The total thickness should be 2mm on walls and
3mm on floors.
SpECtite CW100 is supplied in 22.1kg two part
packs.
A complete mixed pack will cover approximately
11.0m² at 1.0 mm thickness depending on the substrate profile
