Elite Airtight

Achieve airtightness in your concrete block walls - using paint!

Elite Airtight is a more economical choice than the leading brand matt emulsion

Concrete block walls can leak the air in a building at up to 80 cubic metres of air every hour through each square metre of surface, at that rate it won't take long for the warm air inside to escape from the building, resulting in increased heating costs & carbon emissions.

We have developed Elite Airtight to provide a fast and economical solution to the problem. Not only does Elite Airtight offer an airtight finish, it is also fully washable for easy maintenance, it is available in white and can be tinted to most pastel colours, it can be left as an acceptable surface in any public or private areas, Elite Airtight+ is also available with silver ion antimicrobial additives, creating an antimicrobial surface that will last as long as the coating.

The alternatives

• Plastering - expensive, time consuming, messy, requires painting
• Plaster board - expensive, time consuming, not airtight, requires painting
• Blockfiller - more expensive, higher water content/less solids, not tested for airtightness
• Parge Coat - similar price, slow to apply, poor quality surface, not washable
• Paint - similar price, not airtight unless many coats are applied, unattractive finish
• Bare block - no additional cost, not airtight, poor quality surface, unattractive finish, poor light reflectance

Elite Airtight has been tested for airtightness by an independent laboratory and has received a 100% pass when applied to standard cellular blocks, which were leaking 80m3/hour/M2 at 50pa. before application of Elite Airtight coating and leakage "too low to detect" after application of Elite Airtight. The test was carried out on standard cellular blocks - applying Elite Airtight to blocks with smaller holes & fissures or onto paint quality blocks will result in less paint being required to complete the job.

Architects, specifiers and builders now have the option of specifying standard concrete blocks (where appropriate) for quick and economical construction projects and for the resultant walls to have a washable, airtight and decorative finish.

Elite Airtight is also ideal for use in refurbishment projects - making significant improvements to the airtightness of the building.
