Application Information
Instructions for use

Application:

ARMATUREA H1 must be spray applied using a plural-component spray equipment. For application guidelines, please contact Colmef.

Top Coat

The system is not UV resistant. Therefore, a proper top coat is needed for exposed application.

Priming:

Concrete

A primer is generally needed to achieve an adequate adhesion. Monneli Ureaprime EP1 can be applied at 100microns DFT.

Metal/Steel

If priming is needed, this should be done within 8 hours after the sandblasting to prevent any flash rusting.

Machine Conditions

Mixing Ratio 1 : 1 (volume)

Component Temperatures

(Depends of weather condition)

70-75 ºC

Component Pressure 120 -180 bar

Mixing

Use 1:1 ratio pump, with appropriate material heaters, as required for individual application.

Environmental Conditions

Substrate Ambient Temperatures 5 ºC  - 35ºC
Substrate Moisture Content ≤ 4%
Relative Humidity ≤ 85%

Cleaning

Clean equipment immediately after use. Cured product may be disposed of without restriction.  The un-cured isocyanate and resin portions should be disposed of according to local government regulations.

Surface Preparation

Concrete

The surface of the substrate shall be sound, clean and uncontaminated. This preparation shall be such as to leave a sound expose surface free from dust, loose particles and any deleterious matter. If the surface is defective or has laitance, it must be cut back to a sound base. New concrete or cementitious surfaces should be at least 28 days old and have moisture content not exceeding 5%. Old or existing surface should be refurbished mechanically to ensure clear and sound substrate. Concrete must have a minimum pull off strength of 1.5 N/mm2.

Metal

The metal surface needs to be prepared by means of sand blasting to near white. The surface profile will ensure adequate mechanical adhesion. Solvent cleaning is needed to remove the oil and grease.
