Because high-rise buildings are often occupied by a large number of residential and / or commercial tenants, small leaks or issues with plumbing and drainage can quickly escalate into major disruptions.
Yet when they need attention, these pipes and drains are not the easiest to access! They may be buried behind concrete, or soar many metres above ground.
At times like these, we may turn to epoxy brush coating as a preventative and highly targeted relining solution for hard to reach areas, rather than SIPP (Sprayed-in-Place Pipe) and CIPP (Cured-in-Place Pipe) relining.
What is Epoxy Brush Coating?
Brush coating is a method used to reinforce and protect internal pipe surfaces, using existing access points and a specially formulated epoxy resin.
Via the advanced Picote Brush Coating System™ (dual rotating brushes connected to a specialised coating pump) multiple layers of this 100% solids resin are evenly distributed throughout the pipe’s interior. Application begins at the far end of the pipe and moves back toward the access point, ensuring consistent coverage.
Once cured, the result is a smooth, protective barrier that resists moisture, corrosion, and everyday wear – extending the life of the pipe without the need for excavation.
SIPP and CIPP Relining
Both SIPP and CIPP relining involve installing a full structural liner to restore a pipe’s integrity. Brush coating, on the other hand, is a targeted surface application used to protect and reinforce specific sections using the same epoxy resin.
Brush coating is an ideal alternative when these other forms of pipe relining aren’t viable – such as when pipes have multiple bends or limited access points.
Benefits of Brush Coating with Epoxy Resin
Precise: Brush application method allows for precision control, ensuring successful rehabilitation of old or deteriorated pipes.
Versatile: Can be used in vertical and horizontal pipes from 40mm – 300mm, and all different types and shapes.
Certified Safe: Checked and tested for quality and safety, including for potable water systems.
Preventative: Prevents future damage due to strong adhesion and resistance to corrosion, erosion and chemical exposure – especially useful in pipes showing early signs of internal wear but not yet in need of full relining.
Cost-Saving: Reduces the need for costly replacements and repairs.
Improved Performance: The damp-proof, corrosion-resistant, wear-resistant, and non-corrosive epoxy keeps those pipes free-flowing.
Long-Lasting: Long-lasting durability even under high water pressure and chemical use. Plus, it’s backed by up to 10-year warranty.
No Destruction or Downtime: Not only is no digging required to the premises – but water flow may be able to be restored in as little as four hours (with full curing time 24 hours) – minimising downtime and disruptions.
Comprehensive: This technique de-scales, de-greases, and brush coats the piping all in one, whereas other methods may require different tools and techniques.
Environmentally Friendly: Epoxy is an eco-friendly choice as it contains no harmful chemicals, nor does it require adding to landfill as your existing pipes are left in place.
What is Brush Coating Useful For?
Brush coating pipes can be a highly effective technique for:
- High-rises and multi-storey buildings, especially where there’s limited access to vertical pipework like downpipes.
- Pool plumbing systems, which often have narrow pipework and tight bends.
- Property managers and strata title managers looking to prolong the lifespan of existing infrastructure.
- Commercial and construction projects, where access for full relining may be restricted or not yet required.
- Junctions, bends, and hard-to-line spots that need targeted protection.
