If you’re updating your home’s exterior and looking for the perfect paint to finish off your render, look no further than Silicone Paint. At EWI Store, it's one of our most popular topcoats and for good reason. We often get questions like:
-
“What is Silicone Paint?”
-
“What can I use Silicone Paint for?”
-
“How is it different from Silicone Render?”
In this blog, we’ll break it all down for you, including why Silicone Paint is the best masonry paint on the market today.
What is Silicone Paint?
Silicone Paint is a high-performance, breathable masonry paint used to enhance and protect external walls. It's ideal for:
-
Refreshing existing Silicone Render
-
Sealing Mineral Render
-
Providing a decorative finish on solid wall properties
Thanks to its hydrophobic properties, it repels water, dirt and pollutants, making it especially well-suited to urban, humid or exposed environments.
Even better? It comes in thousands of colours, mixed on the same day at EWI Store branches using our advanced Render Colour Tinting Machines.
Silicone Paint vs Silicone Render: What’s the Difference?
The key difference lies in function:
-
Silicone Render is a textured topcoat render that forms part of a render or EWI system.
-
Silicone Paint is a smooth, breathable masonry paint used over render for added protection and longevity.
Both contain silicone and offer water-repellent properties. However, over time, even Silicone Render can appear tired – that’s where Silicone Paint comes in. It gives the facade a fresh, vibrant look while providing another layer of defence against the elements.
Why Choose Silicone Paint?
Here’s why Silicone Paint is a smart investment for your property:
✅ Breathable – allows trapped moisture to escape
✅ Waterproof – prevents water ingress and lime bloom
✅ UV-resistant – colour remains vibrant for years
✅ Frost-proof – withstands freeze-thaw conditions
✅ Easy to apply – smooth consistency over existing renders
Top Tip: We always recommend sealing Mineral Render with Silicone Paint. Mineral Render dries rapidly but can be prone to lime bloom if left uncoated – a quick application of Silicone Paint prevents this and locks in the colour.
Can I Use Silicone Paint Indoors?
Absolutely! While Silicone Paint is formulated for external use, its moisture-resistant properties make it a great choice for interiors prone to damp, such as:
-
Bathrooms
-
Kitchens
-
Utility rooms
-
Basement walls
Many of our customers also use it on garden walls or in outbuildings to prevent organic growth.
