* Material consumption depends on the quality of substrate preparation, application method, tools used, skill of the workers and may differ from the specified values.
** At t (+20±2) ℃ and relative air humidity not more than (65±5) %. When the temperature decreases or humidity increases, the drying time may increase. At air temperatures below +15℃ or relative air humidity above 65%, apply the next coat of primer no earlier than after 24 hours.

A special insulating primer used before applying FIRE STOP non-combustible paint on various types of substrates. The use of Bergauf Techno Primer Isol ensures compatibility and adhesion of FIRE STOP non-combustible paint with the substrate, absence of chalking, and high strength and performance properties of the coating.
The primer forms an opaque "breathable" coating, levels the absorption capacity of the substrate, improves interlayer adhesion due to micro-reinforcement of the substrate, and promotes more uniform application of subsequent paint layers. Easy to apply, dries quickly.

Used for treating concrete, brick, cement, gypsum, polymer plasters or putties.
The primer can be used in rooms with normal and high humidity.

Available in a fixed color palette: milky white

SUBSTRATE PREPARATION
Substrate preparation should be carried out in accordance with SP 71.13 330.2017.
The substrate must meet the following requirements:
  concrete, reinforced concrete, brickwork aged over 28 days and relative humidity not more than 4%
  cement, cement-sand, cement-lime, lime plasters and putties aged over 14 days and relative humidity not more than 4%
  polymer putties aged over 3 days, relative humidity not more than 1%
  gypsum plasters and putties aged over 3 days, relative humidity not more than 1%.

Clean the substrate from dust and dirt. Remove unstable layers of old paint and whitewash from previously painted surfaces.
Sand hard and firmly adhering glossy surfaces to a matte state, remove sanding dust. Surfaces previously covered with chalk or lime paints must be thoroughly cleaned until completely removed.
If necessary, fill irregularities with putty, then sand the dried surface.
Strengthen loose (soft) gypsum plasters, putties and polymer putties with Bergauf Techno Primer or Bergauf Tiefgrunt deep penetration primer.


APPLICATION PROCEDURE
The surface to be treated must be strong, dry, clean and free from substances that prevent adhesion, substrate temperature for work from +5°C, room temperature during paint application from +5°C to +35°C, relative air humidity below 80%.
Stir until smooth before use, do not dilute.
Apply to a prepared dry clean surface with a roller, brush or sprayer.
Recommended number of primer coats depending on the type of substrate:
— gypsum plasters and putties: 2 coats
— polymer putties: 1−2 coats
— cement plasters and putties: 1−2 coats
— concrete: 1−2 coats
— drywall: 1−2 coats
— brick: 1−2 coats.

Apply FIRE STOP non-combustible paint to the primed substrate no earlier than after 4 hours, provided the temperature regime is from +15°C and relative air humidity is not more than 65%.

At temperatures below +15℃ or relative air humidity above 65%, the drying time of the primer before painting increases. The strength gain time can reach 14 days.
Applying FIRE STOP non-combustible paint over undried primer is unacceptable!

Store and transport in tightly closed containers at temperatures not less than +5° and not more than +35℃. Protect the bucket with the product from excessive heating and avoid storage under direct sunlight. Do not freeze. Subject to storage conditions, the guaranteed shelf life in closed factory packaging is 24 months from the date of manufacture. During storage, product separation may occur, which is easily eliminated by stirring. Keep partially used product in a tightly closed container and use as quickly as possible.
The product is fire- and explosion-safe, and does not contain flammable components.
