Rempro Thermal Paint 5 Litres - Premium Anti-Mould & Anti-Condensation Wall Treatment with Glass Bubble Technology (Textured)
Rempro

Rempro Thermal Paint 5 Litres - Premium Anti-Mould & Anti-Condensation Wall Treatment with Glass Bubble Technology (Textured)

Why we love it
  • Prevents black mould formation.
  • Uses advanced Microsphere technology.
  • Independently tested for efficiency.
Main Highlights
  • BLACK MOULD PREVENTION - Rempro Thermal Paint is a specialist anti-condensation paint to stop mould and dampness caused by condensation. Our thermal paint can be used in various applications where condensation can create problems where moisture forms and is perfect for cold walls, ceilings and humid areas such as bathrooms and kitchens.
  • MICROSPHERE TECHNOLOGY - Contains glass microspheres designed to maintain surface temperatures on treated substrates; this increases the dew point compared to an ordinary emulsion, reducing the chance of condensation forming. Rempro paint can be used on most surfaces, such as painted/wallpapered walls and ceilings, new and old plasterwork, brickwork, concrete, galvanised steel and most paintable plastics.
  • UNIQUE ANTI-CONDENSATION PAINT - Unlike other anti-mould or anti-condensation paints which contain biocides or simply only absorb moisture, Rempro anti-condensation paint can be overpainted and is an ideal solution for cold, exposed walls or areas where insulation may be missing or inadequate.Â
  • INDEPENDENTLY TESTED - Independent tests confirm that surfaces treated with Rempro paint take twice as long to cool down when compared to ordinary emulsion paint. Condensation takes 57% longer to form on Rempro coated surfaces compared to ordinary emulsion paint.
  • UK MANUFACTURED - Rempro is a family-owned company specialising in building chemicals for remedial control and prevention. Our products include damp proofing treatments, insecticidal and fungicide control, path patio cleaners and anti-condensation thermal paints. All our products are designed and made in Britain and used by amateur and professional users.
