AY&B Epoxy Aluminium Primer is a two component primer utilising state of the art chromate anti-corrosive technology designed for use on aluminium structures, plate and extrusions and galvanised substrates.

It has been developed for use above the waterline (non-immersion) to provide the very best adhesion to aluminium substrates, and for optimised control of  filiform corrosion.

Epoxy Aluminium Primer is recommended for:

  • Launches, dinghies, yachts – topsides, cabin tops, decks, internal areas, void spaces, masts & spars

  • Superior adhesion to aluminium surfaces

  • Resistance to filiform corrosion.

Alternatively for Aluminium Marine projects you can also use Altex Multipurpose Primer or Altex Epoxy Primer. 



Altex Epoxy Barrier Undercoat is a high performance, sandable epoxy high build coating which is both very corrosion and water resistant.

Epoxy Barrier Undercoat is recommended for:

  • Topside & Superstructure final sealing to provide an optimum surface for finish coating

  • As a high build surfacer to remove defects and achieve a finish suitable for application of Altex Polyurethane Undercoat or one of the Elite Polyurethane finish coats

  • As a high build barrier coat for below waterline application, used as part of an Altex Antifouling system

  • Direct application to sanded GRP, epoxy laminated wood and epoxy sealed wood

  • Direct application to epoxy faired surfaces

  • Application over Altex Epoxy Primer or Altex High Build Surfacer

  • Priming / undercoating over degreased & sanded aged polyurethanes, epoxies, fairing systems, gelcoats, epoxy laminates & fibreglass



  • Excellent build properties up to 150µm DFT in a two pass application

  • Excellent surfacing and sanding properties

  • Very good corrosion protection

  • Wide maximum self re-coat times for easy project management

  • Very good water and chemical resistance

  • Epoxy Barrier Undercoat may be top-coated with both acrylic or polyester urethane finishes and is especially formulated as an undercoat or sealer under the Altex Elite® range of polyurethane finish coats

  • May be used as a high build surfacer / undercoat for topcoating with Altex Polyurethane Undercoat

  • May be used in immersion service as part of an Altex Yacht & Boat recommended system

Alternatively for Aluminium Marine projects you can also use Altex Polyurethane Undercoat or Surfacer Undercoat. 



Regatta® Gloss Enamel is designed for use as the finish coating for the Single Component Marine topsides systems.

Regatta® Gloss Enamel can be used on :

  • Canoes

  • Tenders

  • Dinghies

  • Trailer yachts

  • Power boats

  • For signwriting

  • Boot stripes

  • For up-grading existing enamel systems, subject to correct preparation and undercoating

And numerous other DIY projects requiring a high quality enamel finish coat.


  • High gloss enamel finish

  • Superior, “long oil” Marine quality

  • Good weathering properties

  • Excellent gloss retention

  • Good application characteristics

  • Compatible with Altex Flattening Paste to reduce the gloss for interior colours

  • May be modified with the addition of Regatta® 2K Additive to speed up cure and enhance overall performance. This effectively creates a “Two Pack” finish coat. (see overleaf)

    Alternatively for Aluminium Marine projects you can also use Elite 321 Brushing Polyurethane.
