QC Liquid Release
Product Information Bulletin 4.202
QC LIQUID RELEASE is a non-pigment method for releasing mat-type
texturing tools from the surface. QC LIQUID RELEASE is an alternative
in situations when QC RELEASE POWDER may be prohibitive.
Uses and Benefits
-
QC LIQUID RELEASE is a release choice for applications where
powdered products would be prohibitive, due to risk of damage
to interior finished surfaces.
-
A nonpigment parting agent, QC LIQUID RELEASE is used for
releasing mat-type texturing tools from wet concrete.
-
QC LIQUID RELEASE will not impede the use of QC PATINA STAINS
or QC SEALERS.
-
Please note that QC LIQUID RELEASE will not give an antiquing
effect to the finished surface. For proper antiquing effects,
QC RELEASE POWDER is recommended. To achieve antiquing effects
with QC LIQUID RELEASE, consider use of QC PATINA STAINS.
- QC LIQUID RELEASE has a pleasant bubble gum scent.
Application
1. QC LIQUID RELEASE is applied just before placement of
most mat-type imprinting tools during the plastic stage of set.
2. Apply QC LIQUID RELEASE by misting the surface with
a pump-up type sprayer equipped with a fan tip. Apply enough QC
LIQUID RELEASE to evenly cover the area to be immediately imprinted
(150-200 square feet) while avoiding evapouration of the material
prior to using texturing mats.
3. QC LIQUID RELEASE may be removed as soon as the concrete
has hardened to the point where it will not scratch or mar easily
(normally 2-3 days). Pressure-washing the surface is the typical
removal method. For hard-to-remove release or for heavy texture
work with release, a mild muriatic solution may be used (15 parts
water: 1 part muriatic acid).
Curing and Sealing Concrete
1. For curing concrete treated with QC LIQUID RELEASE,
choose from a variety of QC cures appropriate to project requirements:
QC CLEAR CURE, QC COLOUR CURE or QC COLOURWAX (See separate Product
Information Bulletins for complete instructions on these products.)
QC CLEAR CURE and QC COLOUR CURE conform to ASTM C 309.
2. If a liquid membrane cure is not appropriate, then new,
nonwrinkled, nonstaining, reinforced, kraft-curing paper may be
used.
3. After release has been washed from the surface and once
concrete has dried to a uniform colour, sealing the concrete may
take place. For finish sealing concrete, choose from a variety of
QC sealers appropriate to project requirements: QC CEMSEAL, QC SOLVENT-BASED
SEALERS, QC CEMGUARD or QC SURPRO. (See separate Product Information
Bulletins for complete instructions on these products.)
Maintenance
It is highly recommended to develop and follow a routine maintenance
schedule for all coloured concrete so that it maintains a top-quality
appearance. Coloured concrete installations should be routinely
inspected, cleaned and resealed as required by local conditions.
Cleaning and resealing schedules will depend on a number of factors
including, but not limited to, volume and intensity of traffic,
maintenance procedures and weather.
Coverage Guidelines
-
Note – Actual coverage may vary depending on the application
method, wind conditions, texture of concrete prior to application,
and other local conditions.
-
Under normal conditions, QC LIQUID RELEASE will cover approximately
300 square feet per gallon.
Package Sizes
QC LIQUID RELEASE comes in 1-, 5-, and 55-gallon containers.
Shelf Life
QC LIQUID RELEASE has a shelf life of one year.
