Altamira Topcoat

Acrylic and emulsion sealer for painted and resilient surfaces


The protective layer over an Altamira finish — gloss for exteriors that take salt spray and UV, semi-gloss for a quieter sheen indoors.

Use it for

  • Sealing Altamira Ryolitte, Scorria, and Toscanna finishes
  • Surfaces exposed to salt water spray, UV, and dirt
  • Floors and walls that need stain protection
  • Where a specific level of sheen is wanted

Why this one

  • Blocks water and stains
    Excellent resistance to water and to both water-based and oil-based stains
  • Prevents efflorescence
    Stops the white residue forming on treated surfaces
  • Stands up to UV
    Excellent resistance to ultraviolet rays — the gloss is rated for salt water spray too
  • Protects against abrasion
    And against skid marks on floors
  • Enhances the colour
    Deepens the colour of the finish underneath — gloss can darken it slightly
  • Dries fast
    Gloss is set to touch in one minute and dry hard in ten
