Render in Ireland — Cement, Lime, Silicone, and Acrylic, Compared

Render in Ireland: cement €80–€140/m², lime €100–€160/m², silicone €110–€170/m², acrylic €90–€140/m². Cement is the cheapest and most common but cracks over time (especially on EWI). Lime is vapour-permeable, traditional, used on heritage and natural-finish builds. Silicone is the premium, most weather-resistant, self-cleaning. Acrylic is flexible and crack-resistant, mid-cost. For new self-builds on blockwork with EWI, silicone or acrylic on a cement base is the standard. The EWI system typically specifies the render — don't mix and match. Most EWI systems come with a 10-year render warranty. Repaint every 15–25 years depending on exposure.

Frequently asked questions

What is the cheapest render in Ireland?

Cement render: €80–€140/m² installed. Most common on new build. Cracks over time, especially on EWI. Repaint every 15–25 years.

What is the best render in Ireland?

Silicone render: €110–€170/m². Most weather-resistant, self-cleaning, flexible. Premium option. Standard on most EWI systems.

Can I render over EWI?

Yes, with the correct render system. Most EWI manufacturers specify a base coat, mesh, and finish render. Don't use a generic cement render on EWI — it will crack.
