It's a Coating, Not a Paint!

We have manufactured Walltex for over 30 years. It is tried and tested and we have the proof of performance to back this up! We use the best weatherproof and most flexible solvent based resins which are blended with titanium dioxide, zinc oxide, silicon, fungicide and most important of all, MICA.

MICA is a volcanic material to resist cracking and give extreme durability and weathering. This formulation gives long lasting colour retention and longer life than normal paints.

  • Concrete
  • Metal
  • Masonry
  • Blockwork

When do I need to use the primer kit product?

Do I need to use the primer kit on the whole wall?
Small areas can be spot primed or the whole wall can be primed. See Primer Kit product section for further details.

Does Walltex Smooth Coating cover hairline cracks?
Yes, very successfully. Any cracks over 2mm will require spot priming or filling.

My through coloured/acrylic render is only 3 years old and is looking patchy. What can I do?

Walltex All Weather Coating Test Summaries

FLEXIBILITYBS.3900 (1970) Part E1Walltex contains POLYBUTENE for flexibility. It can be coated on to a piece of plastic and bent through and angle of 180° without cracking.
RESISTANCE TO EXTREME TEMPERATURE Walltex is not damaged by temperatures as low as -20°C or as high as +120°C.
WATER VAPOUR PERMEABILITYBS 3177 (1959)The tests show a permeability of 4.5 – 5.0 grams /M² per day when tested at 25°C and a relative humidity differential of 75%.
LIQUID WATER PERMEABILITYBS 473 (1967)The result is 1.3 ml/cm x 10-6. The results show RETONEX is virtually impermeable towards liquid water and the permeability values are comparable with bituminous roofing felt.
EFFECT OF FIREBS 476 (1971) Part 7The non-combustible inorganic constituents retard the surface spread of flame over treated surface. Class 1 was achieved.
RESISTANCE TO HUMIDITYBS 3900 (1966) Part 2The texture of the coating was unchanged. Adhesion to brick and plywood is excellent.
RESISTANCE TO SALT WATER, SULPHIDE STAINING AND ACIDIC CONDITIONSBS 1391 (1952)No signs of deterioration were observed.
RESISTANCE TO ALKALIES FROM THE BACKGROUNDBS 3900 (1966) Part FThe tests showed no blue discolouration and Walltex showed good adhesion and was unchanged after the test.
COLOUR FASTNESS TO LIGHTBS 2782 (1982) Part 5 Method 540BWalltex shows excellent colour fastness when exposed to different light sources over extended periods. BS Fastness No.7 or better.
RESISTANCE TO FUNGAL GROWTHBS 3900 (1971) Part G6Walltex contains BIOCIDE to prevent fungal growth or mould growth.
WEATHER RESISTANCE (ACCELERATED WEATHERING TESTING)BS 3900 (1971) Part F3Shows no signs of flaking, peeling or embrittlement when subjected to an accelerated weathering test. This continuous testing shows the material to be capable of weathering externally in the United Kingdom without serious defects developing for 20 – 30 years.
CLEANING TEST Walltex is self-cleaning by rainfall, but can be cleaned by hosing down. Walltex will withstand over 5000psi pressure washing without losing adhesion
