Question 1

What is wall coating and what does it do?

Accepted Answer

Wall coating is a protective treatment applied to clean exterior render or painted brickwork. It creates a barrier against moisture penetration, inhibits future algae and moss growth, and extends the clean appearance of your walls significantly. It is particularly effective in Ireland's damp climate where growth returns quickly on untreated surfaces.

Question 2

How long does wall coating last?

Accepted Answer

A good quality wall coating in Irish conditions typically protects for five to ten years. Results vary based on wall orientation, exposure level and the product used. North-facing walls with heavy tree cover may see growth return sooner.

Question 3

Is wall coating the same as exterior masonry paint?

Accepted Answer

No. A specialist anti-algae wall coating is a protective sealant, not a decorative paint. It is applied to preserve the existing appearance of the render while providing biocidal protection. It is clear or subtly tinted and does not change the wall colour.

Question 4

Does wall coating need to be reapplied?

Accepted Answer

Yes, after the protection period. Rather than allowing growth to return and then cleaning again from scratch, we recommend inspecting the wall and reapplying coating before the protection fully expires. This keeps the exterior consistently clean at a lower ongoing cost.

Question 5

Can wall coating be applied to damp walls?

Accepted Answer

No. The surface must be clean and dry for coating to bond correctly. Applying coating to damp or contaminated surfaces leads to premature failure. We check surface conditions before any coating application.

Question 6

Will wall coating change the appearance of my render?

Accepted Answer

Wall coatings are typically clear or very lightly tinted. They may add a subtle sheen to the render surface but do not dramatically alter the look. The main visible change is the clean, bright appearance of the freshly coated render.

Question 7

Is wall coating breathable?

Accepted Answer

Yes. The products we use are breathable, which is essential for render walls. A non-breathable coating traps moisture inside the wall, which can cause paint blistering, render delamination and damp problems. Breathable coatings allow the wall to release moisture vapour normally.

Question 8

Can you apply wall coating to new render?

Accepted Answer

New render needs to fully cure before coating is applied, typically a minimum of four to six weeks. Applying coating to uncured render can cause problems with adhesion. We can advise on the correct timing for your specific render type.

Question 9

Do you offer wall cleaning and coating as a combined service?

Accepted Answer

Yes. We regularly carry out both the clean and the coating application on the same visit or across two consecutive visits depending on drying time. Combining the services is the most cost-effective approach.

Question 10

How much does wall coating cost?

Accepted Answer

Wall coating cost depends on the property size, number of elevations to be coated and scaffold or access requirements. We provide free, itemised quotes. Contact us for a no-obligation assessment.
