BOSCOSEAL PU - LT EX. BOSTIK

DESCRIPTION

Bostik BoscoSeal Top – LT is a one-component, ready to use, highly elastic, cold applied, aliphatic polyurethane waterproofing top-coating membrane with excellent mechanical and chemical, thermal, UV resistance.

FEATURES AND BENEFITS

•     Easy and fast application

•     Provides a seamless waterproofing membrane

•      Highly resistant  to abrasion, water  and root penetration

•      Unaffected by weather  conditions. Provides excellent weather and UV resistance

•     UV and colour stable

•     Provides “easy to clean” surface

•     Water vapour permeable

•      Very good abrasion resistance and suitable for walkways, pedestrian traffic

•     Crack bridging capability up to 2 mm

•      Provides excellent thermal resistance over a temperature span of – 30 ºC to + 90 ºC

•      Resistant   to  salty water,   aqueous  solution, bases, diluted acids, aliphatic solvents, benzene and mineral oils

•      Impregnates  by penetrating  deeply into all mineral and concrete  surfaces with high adherence

•      Fills the  non-structural   capillary cracks  by decreasing water-absorbency of the concrete construction

•      Hardens the upper surface of the concrete by deeply penetrating into the surfaces.

APPLICATION INSTRUCTION

1.   After the Boscoseal PU-X, Bostik BoscoSeal Top – LT has be to be applied in a short period of time as a topcoat (not later than 36 hours)

2.  Bostik BoscoSeal Top – LT has to be stirred well with an electrical mixer before the application.

3.  When the product becomes homogenous apply the product with a brush or roller until the surface is fully covered.

4.  Optional, if a 2nd coat is needed, it has to be applied within 3 – 6 hours (not later than 36 hours)

5.   As an option, I can also be applied by an airless spray.

AREAS OF APPLICATION

•     Roofing

•     Balconies, terraces

•     Pedestrian decks and walkways

AFTER APPLICATION

Newly applied surfaces should be protected from water min for 4 hours The Bostik BoscoSeal Top - LT is slippery when wet  or during rain. In  order to get an anti-slip surface dry quarz sand can be sprinkled during curing period of the membrane.

PACKAGING

25 kg and 5 kg metal can

COVERAGE

Approx.  0,150  kg  /  m² per layer depending on the absorbency  and  smoothness   of  the   surface.  The coverage amounts are theoretical and it is recommended to  do coverage-controlled sample application before treatment.

WARNING

For the best results, do not apply the Bostik BoscoSeal Top – LT over 0,2 mm dry film thickness per layer. Low temperature   retards  the  curing process  and  high temperature accelerates the curing process.

STORAGE

•     They should be protected for water, frost and adverse weather conditions

•     They should be kept dry and cool on wooden pallets at between +10°C and +25°C in moisture free conditions.

•     The opened products should be closed immediately and consumed first

•     Maximum 3 buckets should be stocked on each other.

PREPARING THE SUBSTRATE

•      The dehumidified surfaces should be stable, binding, clean and grease-free

•     Maximum moisture content should not exceed 5%.

Substrate compressive strength should be at least

25MPa, New concrete structures need to dry for at least 28 days

•      The surfaces with bitumen, acrylic and tar should be cleaned until no residues remain and then primed with the Boscoprime 3 before application

•      Porous  substrates   should  be  primed  with  the Boscoprime 1 and the non-porous or glazed surfaces such as metal, ceramic tiles, old coatings should be primed with the Boscoprime 3 before application

•      After the priming Boscoseal PU-X has be to be applied in a short period of time as a basecoat.
