Description
PRYMER FAST 500
Very fast drying, odorless polyurethane primer
¤Description
PRYMER FAST 500 is a single component polyurethane primer
with low emission of volatile organic compounds and very fast
drying. PRYMER FAST 500 is suitable as a dust remover,
surface consolidation and for the waterproofing of
cement screeds. PRYMER FAST 500 is suitable as
antidust in anhydrite screeds and with system of
underfloor heating and cooling.EC1R CERTIFICATE.
PRYMER FAST 500 can contribute to the achievement of the IQ
CREDIT 4.1 according to the GEV parameters dated 03 March 2009
because it complies with the requirements of the LEED certification protocol
(Leadership in Energy and Environmental Design).

¤How to use
Restoration of lean or dusting substrates
Vacuum the substrate dust very well. Apply one
coat of PRYMER FAST 500 with a 6/8 mm roller or flat brush
3x13cm or 4x14cm, in quantities equal to approximately 120 ÷ 150 g/m² in
regular and uniform way. Absolutely avoid accumulations
of product in the deep crazing of the substrate, otherwise
the total hardening of the product itself will be drastically
stretched with non-stick brittle film formations that
they alter the hardening of the reactive glues up to inhibiting it
complete catalysis.
After about an hour and within the following 24 hours we proceed to the
laying parquet using only reactive adhesives: UNISIL,
STICKERS ELASTIC, STICKERS 327 PU, STICKERS HERCULES,
ADESIVER 501 EP, SIGOL (see relative technical data sheets).
In case you have to carry out subsequent smoothing with products
self-leveling or if parquet is expected to be laid in times
longer than those mentioned above, sprinkle with QUARTZ (0.8
mm ÷ 1.2 mm) the entire surface treated with primer again
fresh. Before applying the self-leveling compound or adhesive,
previously vacuum the sand not incorporated in the primer.
If the sandblasting operation is not carried out, it is necessary
vigorous sanding with coarse grain (36-40) before
drafting of levelers or adhesives.
Do not pour the product into the original container if necessary
advanced.
Vapor barrier
PRYMER FAST 500 performs a good "steam barrier" action on
substrates with residual humidity up to 5% with the carbide method
for screed thicknesses of 6 cm.
Thoroughly vacuum the residual dust from the substrate. To apply
the first coat of PRYMER FAST 500 with a 6/8 mm roller
or with a 3x13cm or 4x14cm flat brush, in a regular manner and
uniform in quantities equal to about 120-150 g/m² avoiding
absolutely accumulations of product in the deep crazing of the
substrate, otherwise the total hardening of the product itself
will be drastically stretched with brittle film formations
non-stick products that alter the hardening of reactive glues.
After about 45-50 minutes, apply a second coat of PRYMER
FAST 500 in the same way as before. After about an hour
and within the following 24 hours, proceed with laying the parquet
using only reactive adhesives: UNISIL, ADESIVER ELASTIC,
ADESIVER 327 PU, ADESIVER HERCULES, ADESIVER 501 EP,
SIGOL (see relative technical sheets).
If exposure times beyond 24 hours are expected, it is necessary
apply a third coat of PRYMER FAST 500 and sprinkle with
QUARTZ (0,8 mm ÷ 1,2 mm) the entire surface treated with primer
still fresh. When applying the adhesive vacuum
beforehand the unalloyed quartz.
NB On anhydrite substrates and heated substrates
the application of PRYMER FAST 500 with "barrier" function
steam" cannot be performed.
