Surface requirements

  1. Should meet SNiP 3.04.01–87 requirements.
  2. Air temperature from +5 °C to +35 °C.
  3. Surface humidity is not higher than 4 %.
  4. Surface temperature is 3 °C above the dew point.

Surface preparation

  1. Wash the dirt, corrosion products and scale.
  2. Clean the metal surface to the first degree in accordance with GOST 9.402 or Sa 2.5 ISO 8501–1 and a Rz degree of roughness of at least 60 microns in accordance with GOST 25142 or ISO 8503–2.
  3. Clean the concrete surface with a sanding machine or abrasive treatment.

Attention! Do not wash the surface with water.

Application

  1. Mix component A for 5 minutes.
  2. Pour component B into the container with component A . For a partial application use the ratio A:B–100: 50 by weight.
  3. Stir for 2 minutes until the liquid takes homogeneous form. Dry for one minute and re-mix for another minute. Mix thoroughly at the bottom and on the sides of the bucket.
  4. Let the mixture stand for 2 minutes to release the entrained air.
  5. Evenly distribute 0.1–0.2 mm. of the mixture with a roller, brush, or squeegee on the prepared surface.
  6. Wash the tools with toluene, xylene or solvent 646,once work is complete
  7. When coating is complete, isolate the room, blocking access to draughts, polluted air and insects.
  8. Curing time at 20 °C: 24 hours.

Health effects and precautions

Follow the SNiP III-4-80 safety regulations. Use personal protective equipment: a gas mask or protective mask, special clothing, covering all areas of the body, gloves, shoes.

Storage recommendations

Shelf life is 6 months from the date of manufacture at 20 °C and without opening buckets.

Problem solution

Problem: Bubbles, cavities, untreated or brittle areas on the surface, and the ingress of small debris and dirt particles during filling.

Solution:

  1. Remove the defective area with a sander or sandpaper.
  2. Clean the base.
  3. Re-apply a layer of Himtrust PU- Polish
