Care & Maintenance Guide Exterior Facade


What does 'Acrylic Texture' mean - I thought it was a render?

"Render" means, cement render, sometimes just painted with a thin paint topcoat. "Acrylic Texture" means the system from the substrate up is an integrated, flexible multilayer polymer system (not rigid cement render)

How long will the coating system last?

An AcraTex Texture System is permanent. Like all surfaces exposed to the elements, preventative maintenance will keep it looking its best and preserve its optimum performance.

What maintenance is required?

The coloured facade of your project represents a sense of your style and significant investment), so keeping it in good shape makes sense. As a rule of thumb, wash the surface down every 12 -18 months (more often in seaside locations). This not only removes surface contaminants but forms an inspection routine that's a good idea generally. Check other building related elements important to preserving your investment at the same time. Look for any areas of water ponding near walls, any loose or cracked sealant at joints and around windows, debris accumulated against walls, the state of gutters and timber, any signs of moisture under eaves - all elements that routinely maintained and corrected early will extend the trouble free life of all building elements.

Do I ever need to recoat?

Ultimate Life Cycle costs of the total facade system are optimised when AcraTex AcraShield (the Final Weatherproofing topcoat) is re-applied after 7-10 years. This ensures the integrity of the weather proofing system and provides the opportunity to address typical longer term building maintenance issues - such as building movement. Preserving the investment is just one good reason, secondly a "10 year refresh" maintains the properties visual impact "as new".

Can I change the colour?

Style and Colour are emotive and likely were very important in the original design choices. You can update at extended 7-10 year maintenance intervals or at any time. Dulux recommends AcraTex AcraShield. This is a high build (2-3 times normal paint) , flexible coating which is applied like normal paint.

How tough is the surface - what do we do if the surface is damaged?

The surface is very resilient. AcraTex full acrylic systems have a "shock absorbing" effect compared to hard, brittle render, but can still be damaged. If it's a minor blemish (just to the surface layer), then this can be touched up with the same AcraShield outer skin layer that was applied at construction time. In residential projects, agree with your builder to leave a "maintenance pack" including a portion of the AcraShield topcoat used on the project. Blemishes can be touched up by "brush & sponge" method, diffusing the repair to blend in. If the damage goes through the coating (e.g. a corner is physically broken by impact), then this can be repaired, but may require more materials. Ultimately it may be more efficient to call a coating expert for advice.

I have seen some mould on the surface, what should I do?

Organic growth generally requires 2 elements: A nutrient (or food source) and moisture. The coating surface can't "grow mouldy". Where you see mould on a surface you need to look for the causes - generally dirt accumulating on the surface (containing contaminants or the "food source") and excess moisture usually leaks or poor drainage allow the moisture level to stay permanently high. Fix the causes first. There are various surface cleaning agents available to then treat the resultant mould. Check the instruction carefully for safety and suitability on painted surfaces, then test a small area first to ensure no staining occurs. Most importantly, mould on any surface should not be left too long before treatment as staining can occur.
