GRP Lining

What is a GRP Lining ?

Production Design

GRP (glass reinforced plastic) is widely used in industry because it is affordable, extremely durable, and has a range of uses thanks to its flexible manufacturing method.

Due to the method the system is done and the thickness at which it is applied, GRP is a great lining solution when compared to coatings like epoxies and urethanes. GRP has an advantage over coatings in that it will cover cracks and even sizable holes. It is applied in sheets as opposed to wallpapering. Epoxies are painted on with a 0.5mm or so thickness. With a minimum of 3mm thickness, it is feasible to conceal flaws and uneven substrates, providing a very strong yet still flexible costing.

Application Method GRP

  • Grit blasting is typically used to prepare the surface to the standard needed for the application. This guarantees a strong bond between the lining system and the surface.
  • After that, a resin-based primer is applied to all the prepared regions.
  • On all primed areas, CSM (Chopped Strand Mat) is applied. CSM is applied in layers to create the necessary thickness.
  • A mixture of resins is a chemically necessary tissue. is used to increase chemical resistance as well as to stop pinholes.
  • All areas receive a resin wash, which is a mixture of resins. The resin wash is coloured to the desired shade and, when dried, produces a glossy, smooth surface.
  • After being resin cleaned, the liner system is sanded to remove any imperfections. The region has been cleared of any trash and dust.
  • The lining system was finished with a GEL Coat.
