UCRETE UD200
Page 1 of 2
Heavy duty polyurethane concrete flooring system
DESCRIPTION
Ucrete UD200 is a single layer, seamless, solvent-free,
polyurethane flooring system.
It has a textured matt
finish possessing a
wide spectrum
of
chemical
resistance; withstands abrasive wear; has high impact
resistance and withstands direct steam impact.
RECOMMENDED FOR
Ucrete UD200 is recommended for conditions requiring
the maximum of chemical resistance, health and safety
and where thermal situations arise, from cool rooms to
hot environments.
Specific applications include:
•
meat, fish and poultry processing
•
food and beverage production
•
dairies, cheese and milk products
•
cold rooms, chillers and freezers
•
pharmaceutical production
•
chemical plants
FEATURES AND BENEFITS
Expert
application
Installed only by trained and approved
specialist contractors.
Fast
application/r
apid access
Can be applied to 6-day-old concrete
or 2 day old polymer screeds.
Short curing time and 8 hours access
to foot traffic; 20 hours for vehicles.
Hygienic/
safe
Slip
resistant,
non-tainting,
non-
dusting, monolithic (minimum joints),
easy to maintain, microbiologically
inert.
Durable/long
life
Wide chemical resistance, wear and
impact resistant, resists temperatures
from -40°C to 120°C at 9 mm
thickness; 25 years of international
use.
Prepacked
Preweighed/ prepacked for immediate
use; batch to-batch colour matched
for consistency.

APPLICATION
Surface Preparation
Concrete shall be clean, structurally sound and free
from foreign materials, contaminants, oily products and
other debris. Concrete surfaces shall be ‘visibly dry’ with
no standing water. The minimum tensile (pull-off)
strength shall be 1.5N/mm² and concrete shall have
cured for at least 5 days. Concrete substrates shall
incorporate a continuous waterproofing membrane.
Concrete design shall allow provisions for movement
joints, as required. In addition, provision shall be made
for induced joints to allow any shrinkage of the concrete
to occur along defined planes.
All laitance shall be removed. All imperfections such as
holes and cracks shall be repaired and levelled with the
mean level of the surface. For repairing surface
uneveness, EMACO
® concrete repair systems shall be
used.
The whole surface shall be enclosed or impact shot
blasted, surface planed, ground or high-pressure water
jetted. All high spots shall be removed. Surfaces shall
be rendered ‘visibly dry’ by heat or mechanical means.
Remove all loose material and dust by vacuum or
mechanical means.
Priming
Ucrete UD200 shall be applied to a cured scratch coat
of Ucrete MF of 1 mm nominal thickness.
Placing
Ucrete UD200 shall be mixed and applied only by
specialist flooring contractors who have been trained in
the correct application procedures.
CURING
At 30°C, foot traffic access in 8 hours; vehicular traffic in
16 hours.
At 20°C, foot traffic access in 12 hours;
vehicular traffic in 24 hours. Full cure at 28 days.
