What is First Base?
FIRST BASE is a superior sealer that gives floors a clear, protective
coating which shields them from the harsh effects of traffic wear,
spillages and weathering. Because it is water-based, FIRST BASE is
odourless, non-flammable and environmentally responsible. It has
excellent adhesion and stops surface dusting on concrete. FIRST
BASE has a high resistance to UV light and is suitable for both interior
and exterior applications (but is not suitable for outdoor timber decks
exposed to the rain).
Environment
FIRST BASE conforms with all statutory environmental
requirements. It is based on safe ingredients selected to
perform efficiently so there is no waste or damage. FIRST
BASE is non-flammable and water-based. Containers are recycled
wherever possible.
VOC Content:
FIRST BASE contains 0.85 grams of Volatile Organic Compounds per
litre. FIRST BASE therefore complies with ‘green’ standards which
require the VOC content to be less than 7% (ie., 70 grams per litre).
How does it work?
FIRST BASE forms a clear film of tough acrylic inside the surface of the
floor. This film keeps dirt and spillages out and stops dust from rising
out of concrete.
FIRST BASE is an excellent base coating because it fills the porosity in
the floor and provides a smooth, even base for the topcoats to
spread over. This dramatically improves the life of the film.
For use on…
FIRST BASE is a clear, non-slip sealer designed for application to vinyl,
timber, terrazzo, porous stone and concrete floors. Because it sets
quickly, floors can return to service within hours. FIRST BASE is
excellent in food storage areas where solvents are not permitted.
FIRST BASE is a base-coat that is only to be used directly in contact
with the bare floor surface.
Technical Data
Properties
COLOUR – Milky white liquid
ODOUR – Faint
pH = 8.0 ± 0.5
REMOVABILITY – Strippable but requires concentrated
stripper.
Slip Resistance
FIRST BASE passes the Slip Resistance Test under dry conditions as
specified in AS/NZS 4586-1999. It gives a mean Dynamic Coefficient of
friction of 0.90 which is well above the minimum requirement of 0.40.
Coverage
15 - 30 sq. metres per litre on concrete; 30-50 sq. metres per litre
on timber and terrazzo. Pack Sizes Available: 5L & 20L
Application
Surface should be clean, unpainted and free from oil, grease, dirt
and flaking matter. Formwork oils must be removed. Sweep floor
to remove dust and debris.
If necessary, scrub floor clean with HF or other Agar detergent.
To remove loose and flaking material, use a wire brush or high
pressure water jet cleaner.
Timber floors should be stripped free from wax and acrylic
polishes. Terrazzo should be fully stripped and rinsed.
Allow all new concrete to cure for at least 7 days before sealing
(14 days in winter).
On old concrete, remove all traces of mould, algae and fungi with
BLEACH and rinse.
Very smooth concrete may be etched with a dilute (5%)
hydrochloric acid (Spirits of Salts) solution and rinsed thoroughly.
This will produce better sealer penetration and bonding.
Floors must be totally dry before applying FIRST BASE. This is
very important to ensure good adhesion and clarity. If the floor is
damp, the film may dry with a milky, hazy appearance. Also, the
sealer may fail to bond properly to the floor.
Apply FIRST BASE using a brush, short nap roller, paint pad or
string mop. Give floor a generous coating, but avoid puddling.
The porosity of the floor will determine the actual coverage rate.
Try to avoid generating bubbles. If bubbles are left, they must be
broken before the sealer dries by dragging a clean, soft brush or
broom across the wet film.
After the first coat is touch-dry, it must be left for a further 15
minutes before the next coat is laid.
Apply 4 coats, leaving floor to stand for 1 hour to dry between
coats. Floor must be tack free before recoating.
Indoor floors may be further topcoated with 2 coats of
TRAVERSO, 3D-GLOSS or 2020-GLOSS for extra protection
and buffability.
Allow to dry for 2-3 hours before allowing light traffic, or overnight
(12-24 hours) before allowing heavy traffic to use the floor.
Do not apply to very cold floors (10ºC or less).
Do not add water to this product.
Clean Up
Rinse applicators & mops in hot or cold water before the sealer dries out.
Maintenance
FIRST BASE is UV resistant but may show a slight decrease in gloss
after 12 to 18 months exterior exposure. It should then be scrubbed,
rinsed and recoated.
FIRST BASE may be recoated at any time, (after cleaning.)
FIRST BASE offers good resistance to petrol, oils and spillages.
Regular maintenance should include cleaning up such spills by
mopping or scrubbing with NOVADET DETERGENT.
FIRST BASE is not buffable. Where a high gloss is desired, we recommend
top-coating the floor with 3D-GLOSS floor finish and buffing regularly.
