Roofs & Exposed Structures

Exposed concrete decks and structures in Singapore face UV, driving rain and thermal cycling all year. UV-stable polyurethane finishes over suitable primers protect exposed decks, parapets and structures — talk to Rayson's technical team about your exposure conditions.

Common challenges

  • UV degradation chalking and fading standard coatings
  • Thermal movement cracking rigid films
  • Ponding water and constant wet-dry cycling
  • Carbonation and rebar corrosion in unprotected concrete

How Rayson approaches it

  1. Assess falls, ponding and existing waterproofing before specification
  2. Repair cracks and spalls; reinstate falls where needed
  3. Prime with a system matched to the substrate and exposure
  4. Finish with UV-stable polyurethane top coats on exposed surfaces
