Picote Brush Coating

FACTS

  • Renovate old or deteriorated pipes and drains from DN32 to DN300 diameter with the certified Picote Brush Coating™ System
  • Picote 100% Solids Epoxy resin is applied in multiple layers and provides a corrosion resistant, wear-resistant lining (ASTM, NFS 61-5 & WRC approved)
  • Picote’s 100% Solids Epoxy resin is available in dual color (white and grey) so you are able to see surfaces between the layers
  • Renovate entire piping systems like apartment buildings or businesses with minimal disruption, avoiding costly replacements.

We are increasingly encountering unqualified service providers using incorrect products in pipelines, which often leads to further damage. It is crucial to educate yourself and ask the right questions to ensure proper pipeline maintenance. 

 

Why Picote Epoxy is the Preferred Choice for Brush Coating

Pipes Picote epoxy is  preferred choice for brush coating pipes due to several key factors:

Designed for the job:

  • Picote epoxy is specifically formulated for pipe lining applications. This means it’s optimized for adhesion, durability, and resistance to the specific conditions pipes face.
  • Consistent quality: Picote epoxy typically undergoes rigorous testing and quality control, ensuring consistent performance. Application Method Precision coating: Picote epoxy is often designed to be applied with a specific brush coating machine, which ensures even and controlled application for optimal results.
  • Efficiency: The Picote system can often be more efficient than using generic epoxy and manual application methods. Performance and
  • Longevity Durability: Picote epoxy is often engineered to withstand specific pressures, temperatures, and chemical environments, providing long-term protection for the pipe.
  • Proven track record: Many successful Picote installations demonstrate its reliability and effectiveness.
  • Certification and Compliance Standards and regulations: Picote epoxy often meets specific industry standards and regulations, ensuring compliance with safety and performance requirements.

It’s important to note:

  • Cost-benefit analysis: While Picote epoxy might be more expensive upfront, its long-term performance and potential cost savings due to reduced maintenance or replacements should be considered.
  • Testing and evaluation: If considering an alternative epoxy, thorough testing and evaluation are essential to ensure it meets the required performance standards.

Correct Procedure

DC1000E 100% Solids Epoxy
Dual component epoxy used to rehabilitate concrete, PVC, fiberglass, clay, cast iron and ductile iron pipes. Creating a monolythic corrosion barrier or semi-structural repair of decayed and damaged pipes. Designed exclusively for the Picote Brush CoatingSystem.

 

All surfaces to be coated must be dry and clean, free from oil, grease, debris and other contaminants.
Concrete: must be jetted and cleaned removing any loose concrete.
Steel/Ductile Iron: Near-White SSPC-SP10/NACE 2. Acceptable methods: sand blast, chain flail, or Picote Smart Cutterand Side Grinding Panels
Stainless Steel: Nace No. 1/SSPC SP-5 White Metal Blast cleaning is needed and is beyond the capability of Picote cleaning tools. White metal blast cleaning is to be used to clean unpainted or painted steel surfaces prior to applying high-performance protective coating or lining systems. SSPC-SP 5/NACE No. 1 removes all visible oil, grease, dust, dirt, mill scale, rust, coating, oxides, corrosion products, and any other foreign matter on the surface.

 

Number of coats required is dependent on pipe diameter and rehabilitation goal Estimated 30-50 year design life when using Semi-Structural Design Specifications.
Resistance to High-Pressure Water Jetting:
• Minimum 4 coats need to be applied.
• Maximum Jetting Pressure: 2600 PSI (180 Bar).
Corrosion Resistance: After cleaning metal pipes, corrosion will come back even quicker without coating
