Use and Care Manual

Bare Concrete:
Surfaces to be coated must be clean and dry and free of dust, grease, curing
compounds and other contaminants that may block adhesion. Newly poured
concrete must cure at least 30 days prior to coating application. Very dense,
non-porous or chemically treated concrete may require mechanical methods
such as a concrete grinder to remove any bond barriers and open the pores
for optimal penetration. Porosity can be tested by applying one or two ounces
or water onto the concrete. If water is absorbed, the pores are open. If water
beads, the surface is not porous and requires additional treatment.
Wash the surface with DAICH All-In-One Concrete Cleaner/Etcher (as
directed) or a strong TSP (trisodium phosphate) solution to remove oil, dirt,
grease and other chemical contaminants. Remove surface dirt with a pressure
washer (min. 2500 p.s.i.) and then scrub the concrete with the cleaner/etcher
or TSP. A second scrubbing may be required for more soiled or impacted
oors. Remove all rinse water with good drainage or a wet vac to lift water o
the surface. **For most aggressive etching, a mix of 2 parts water : 1 part
muriatic acid can be used. (Add acid into water, NOT water into acid.) Wear
eye protection, gloves and protective clothing. Follow all safety directions.
Apply etching solution uniformly using a plastic sprinkler can and scrub with
a sti broom. When zzing stops, rinse well with clean water and while again
scrubbing with a sti broom to remove loose etching residue (or, alternatively,
a pressure washer with min. 2500 p.s.i.). Remove all rinse water with good
drainage or a wet vac to lift water o the surface. Let the surface dry thoroughly
(ideally below 12% moisture content).
Vacuum any dry, loose residue. If a moisture meter is not available to test
concrete water content, an alternate test method would be to tape a 14” x
14” piece of plastic to the surface, sealing the plastic on all sides for air tight
closure. After 24 hours, if the concrete beneath the plastic is darker in color
than the surrounding area, or if there are water droplets on the plastic, this
indicates excessive moisture in the slab which must be removed before coating
is attempted.
Coated Concrete:
If the concrete is covered with a previous coating that is still sound, it can
be coated with DaiHard100. Scrape up any and loose or peeling paint and
scu the existing paint with sandpaper to add bonding prole for maximum
adhesion. Wash the oor thoroughly to remove any dirt, grease, oil, etc. from
the surface. Allow it to dry completely before coating application.
Mixing:
Mix the Part “A” epoxy base for about 30 seconds prior to blending with
the Part “B” hardener. Pour the entire contents of Part B into the Part A
container, scraping the sides and bottom of both containers to ensure that all
is incorporated during mixing. Stir for three minutes, taking care not to add air
into the mixture. Immediately after mixing, begin application.
Application:
Ambient air, material and oor temperatures are important factors which will
determine pot life and work time of the blended epoxy coating. Temperatures
should be between 60-90°F (15.5-32°C) for approximate pot life as follows:
60 minutes @ 70°F (21°C) , 45 minutes @ 80°F (26°C) , 20 minutes @ 90°F
(32°C). Do not leave mixed epoxy in the container where the mixture will rapidly
heat up and reduce pot life. Immediately pour the activated epoxy into paint
trays and begin roller application (using a 3/8” roller) OR pour some mixed
epoxy directly onto the oor and spread it out with a squeegee applicator in
manageable 100 sq.ft. sections followed by back rolling with a 3/8” nap roller
to even out the coating. Keep going until all mixed epoxy is applied. Do not
overwork the applied coating or disturb already applied sections as this may
insert air bubbles or impact color uniformity of the dry nish.
Residential Garage Floors & Light Duty Industrial:
For most residential garage and other interior concrete surfaces, as well
as industrial oors subject to light fork lift trac, one coat of self-priming
DaiHard100 will provide good results with an coverage rate of 250 sq.ft. per kit.
Heavy-Duty Industrial Floors:
For heavier duty industrial oors subject to daily forklift trac, an initial priming
coat is recommended for best performance. This can be achieved with a
rst thin application (roughly 4 mils) of DaiHard100 as the “primer coat” to a
maximum coverage area per kit between 350 - 400 sq.ft. Application can be
performed with a 3/8” lint-free roller or an epoxy application squeegee pressed
tightly to the oor for optimal penetration. After 6-8 hours or before 24 hours
have passed, a second coat can be applied at an average of about 150 sq.ft.
per kit (10 - 12 mils) using a roller or squeegee/backroll combination. If walking
on the oor before it has dried completely, spiked shoes should be worn while
walking on the surface.
Application Notes:
• When applying to adjacent sections of oor, overlap the previously applied
coating by about 6” to blend uniformly.
• Where possible, use natural break points in the oor (such as expansion joints)
to dictate where new sections are started and stopped, especially if applications
will be continued the following day.
• When performing back rolling, change to a fresh roller periodically for uniform
application as epoxy nearing end of pot life begins to set up on the roller. Mount
the roller on the frame in the same direction every time it is changed.
• The coated oor will be ready for normal use (foot trac) in 24 hours at 70-80°F
and 50% relative humidity. DRIVEABLE IN 48 - 72 HOURS. Do not wash with
chemical cleaners for 5 days after application.
• Where a slip-resistant oor treatment is desired, apply one coat of DaiHard100
at approximately 6 - 8 mils thickness (125 sq.ft. per kit). As you go, broadcast a
light and uniform layer of DAICH Non-Slip Additive into the wet epoxy to create
light surface texture. After 6-8 hours or before 24 hours have passed, apply a
second coat at the same thickness over the surface to lock down the additive
and complete the oor nish.

**IMPORTANT: To avoid applying unblended epoxy material onto the oor
(which can result in uncured sticky or soft areas) DO NOT scrape the inside
of the container after mixing when emptying contents into a paint tray or
onto the oor. Also, do not leave the epoxy container upside down to drain out,
which may deposit unblended material onto the oor. Use only well mixed and
activated epoxy that pours freely out of the can on its own.**
