Coating Application

Coating Application

With a highly trained technical team, Metanano executes coating works in accordance with standardized procedures, ensuring proper techniques and strict quality control at every stage.

Depending on the surface type, we apply specialized application processes:

  • Rusted metal roof
  • New metal roof
  • Walls and concrete

RARE PAINT APPLICATION PROCESS

NEW ROOFING APPLICATION

Surface Cleaning

  • Remove dust, moss, and grease adhering to the surface using a high-pressure washer combined with brushes and cleaning cloths to thoroughly clean the roof surface. Allow it to dry completely.

Apply one coat of anti-corrosion primer

  • Ensure the surface is clean and completely dry before painting.
  • Apply RARE anti-corrosion primer with a standard dry film thickness of 30–60 µm

Apply the first topcoat layer

  • Allow 2–4 hours for the primer coat to fully dry
  • Use a paint sprayer to apply one even topcoat layer with a dry film thickness of 60–90 µm.

Apply the second topcoat layer

  • Once the first topcoat has dried (after15–20 minutes), proceed to apply the second topcoat according to technical specifications
  • Final dry film thickness: 150–240 µm

RUSTED METAL ROOF APPLICATION

STEP 1: CLEAN DUST AND DIRT WITH A HIGH-PRESSURE WASHER

STEP 2: REMOVE RUST BY A SPECIALIZED MACHINE

  • Use a rust-removing machine or a specialized grinder fitted with an appropriate grinding disc or wire brush to thoroughly remove rust, peeling paint, and contaminants.

STEP 3: SURFACE CLEANING

  • Use a brush to remove dust, metal particles, and contaminants after rust removal
  • Use a specialized blower to remove dust and water from gaps and joints, ensuring the surface is completely clean.

ROOF AFTER CLEANING

STEP 4: INSPECT AND ASSESS THE SURFACE AFTER CLEANING

  • Check visually and by touch: no rust, metal particles, grease, or dirt remaining
  • If any area does not meet the requirements, it must be cleaned and treated again
  • Wait until the surface is completely dry before proceeding to the next step

STEP 5: BRUSH/SPRAY SURFACE TREATMENT AGENT

  • Mix the surface treatment agent at a ratio of A:B = 4:1 and stir well before use
  • Pot life of the mixture: within 4 hours after mixing.
  • Application: brush or spray a thin layer to ensure full coverage of the entire metal surface, including gaps and joints
  • Drying time: approximately 4 hours, and proceed with primer application on the same day.

STEP 6: PRIMER

  • Spray 1–2 coats of anti-corrosion primer depending on the    roof structure
  • Dry film thickness: approximately 60–80 µm

STEP 7: RARE TOPCOAT

  • Spray 2 coats of RARE topcoat according to technical standards.
  • Dry film thickness: approximately 130 – 150 µm.
