APPLICATION:
A product specially formulated for primary coating various porous
and adsorbent surfaces. It has high penetration and strengthening
properties, and provides good humidity protection. It prepares
the surface for painting and reduces paint usage.
It can be used on various mineral surfaces, such as: cement
and lime cement plasters, cement sheets, concrete, aerated concrete,
acrylic and mineral plaster, plasterboards, glue paint, joint
less floors, self-levelling floors, tiles, etc.
It makes a good insulation layer for surfaces stained by cigarette
smoke and grease. In the case of newly set concrete elements
it is necessary to test a section for correct coverage.
Note:
Do not use active primer when a bonding primer is required
Priming surfaces that are too "fresh", unseasoned
plaster or other surfaces (with unbalanced air/surface humidity)
are liable to "burn-outs".
PREPARING SURFACES & USAGE:
Surfaces should be clean and free of dirt and grease. With
very absorptive surfaces and thick layers requiring strengthening
the best priming method is applying the primer using the "wet-on-wet"
technique, which will ensure deep enough penetration of the
substrate. In this circumstance it is necessary to dilute
the primer with drinking water in a ratio 1:1. More water
is required when the temperature exceeds 30°C or when
working on a warm surface. With less absorptive surfaces it
is possible to dilute with water or use undiluted.
It can be applied with various tools such as brush, roller
or spray, depending on the absorption of the surface and porosity.
A test should be performed on a few square metres to estimate
the number of layers and consistency required.
Please bare in mind the following:
An over-primed surface will cause paint smearing on the primed
layer (looking up towards the light the surface reflects light
like glass). To cure this problem, dilute the paint until
it is of sufficient consistency to "catch" on the
over-primed surface.
The absorptive quality of the surface should be directly compared
using sprayed water droplets with a sample of low absorptive
material (e.g. plasterboard) until such time as they are similar.
Highly absorptive surfaces greatly reduce the efficiency of
paint, and thus increase costs.
ACTIVE PRIMER, can be used as an insulation layer for surfaces
stained by cigarette smoke and grease. In such circumstance
it should not be diluted. In the case of very greasy surfaces,
3 coats may be required (use "wet on dry" method).
For less greasy surfaces prime and then test. If required
prime with further coats. It should be noted that after multiple
primer layers to counteract grease, the surface will be typically
"over-primed", and thus the first layer of paint
should be diluted in a ratio 1:1.
EFFICIENCY:
Average total usage depends totally on the reason the primer
is being used. For very absorptive surfaces it could be 0.15
-0.22 l/m2. For strengthening and regulating the absorption
for surfaces with medium absorption the usage will be 0.08-0.14
l/m2. For new surfaces where we are balancing the absorption
between different materials (e.g. plasterboard and joining
materials), usage will be close to 0.05 l/m2.
STORAGE, USE AND TRANSPORT:
A.P. should be stored, used and transported in its originally
closed packaging at a temperature of +5° - +35°C (also
includes surface temperature) and in clean dry conditions.
Protect from frost.
BEST BEFORE:
2 years from date of production.

S26 In the event of eye contact wash with large quantities
of water and consult your doctor.
