Will Elite Airtight give me airtightness on the first coat?

This depends on the substrate and condition of the wall. Cracks and holes in the mortar should be filled prior to application of the coating. The test results were achieved by applying two coats at a spread rate of 3m2 per litre per coat. Therefore we recommend a two coat system.

 

Why should I paint my internal walls when I have got cladding/brickwork/insulation between the blockwork and the outside?

When you heat an interior space that has no coating on the blocks, the warm air quickly escapes into and through the blocks, therefore it takes a lot longer to heat up the interior space. If the walls are coated with Elite Airtight the interior reaches the desired temperature much quicker and it takes a lot longer for the heat to dissipate through the walls. 

 

Does Elite Airtight cover all types of concrete blocks?

Yes, Elite Airtight was designed to cover all types of concrete block - for internal use only.

 

Does Elite Airtight cover and provide an airtight finish on other substrates ?

Yes, Elite Airtight can also be used on Concrete, Plaster and Dry-lining, however we have only tested for air tightness on Blockwork - for internal use only.

 

Has Elite Airtight been fire tested?

Yes, Elite Airtight has been tested to BS476 parts 6 & 7 and achieved a Class '0' result. 

 

Is Elite Airtight washable?

Yes (allow to cure for 48 hours first) you can wipe clean the surface of the walls using a cloth and soapy water.

 

Should I use a parge coat or Elite Airtight behind plasterboard?

 

What is the application procedure?

Apply Elite Airtight with a high volume airless spray with a spray tip size of 21- 23 thou. and a fan size of 12 inches, followed by back rolling with a medium pile masonry roller to fill perforations.  Alternatively - although slower - the coating can be applied with a medium pile roller, again ensuring that the fissures and holes are filled. NB The wall should be clean, dry, grease and dust free prior to application. Click HERE to see a video of the application process.

 

Can I apply Elite Airtight to previously painted walls?

Yes, however the surface of the existing paint on the wall needs to be made good, remove flaking paint, dust, grease etc prior to application of Elite Airtight and a test should be carried out prior to full application.

 

Does Elite Airtight leave a smooth surface?

Elite Airtight contains a high level of solids (much higher than most paints and blockfillers). These remain on the surface after the coating has dried leaving a  surface that is fairly smooth to the touch (the contours of the substrate beneath will still be clearly visible). Elite Airtight doesn't leave a flat surface like plastering, but it does leave a washable surface that won't snag clothing or scratch skin, (unlike paint which needs numerous coats to achieve similar results).

 

Is the coating Vapour Permeable?

Yes, the coating will allow moisture trapped in the block to escape.

 

What about walls with efflorescence? 

The wall should be cleaned and coated with a primer sealer first. Pristine Coatings offer a primer sealer which covers 10M2 per litre and costs about £5 for 5 litres - this works out at 10p per square metre (+VAT & delivery).

 

Can Elite Airtight be tinted?

No, Elite Airtight is a very thick, high solid coating which will not mix on the tinting machines, however we do supply a topcoat which can be tinted to any RAL or BS colour code 

 

Can I paint over Elite Airtight?

Yes, if you are applying Elite Airtight to our specification you can apply our Elite Matt or Satin top coats, both are fully washable, they can be tinted to any RAL or BS colours. If you are using another manufacturers top coat, a test for compatibility should be carried out first.

 

Can I specify Elite Airtight for future construction projects?

Yes, just go to our Specification page.  We would be pleased to offer additional advice about any projects you would like to specify Elite Airtight for - whether new build or refurbishment.

 

Does Elite Airtight smell? (re-occupation)

There is almost no residual odour, rooms can be re-occupied the next day.

 

What about VOC's (Volatile Organic Compounds)

Elite Airtight is a water based paint and is well within the 2010 VOC guidelines. Elite Airtight contains max. 29g/l.

 

What is the Light Reflectance Value of Elite Airtight?

The LRV value of Elite Airtight is 92.

 

What about sound absorption?

Elite Airtight significantly reduces the transmission of airborne sound through the walls due to the removal of the holes and cracks in the blocks and mortar. We are currently engaged in carrying out sound absorption tests and will add the actual test results as soon as we have them available.
