What is Thin Coat Render?
A thin coat render is a type of render that is typically applied as one of the finishing coats in a system to provide a decorative finish. Unlike some traditional render systems, they are applied in a relatively thin layer and are available in different types, including silicone and acrylic options. The properties and performance of each product can vary, so it’s important to choose a product that’s suitable for your substrate and project requirements.
Thin coat render systems can be used across a range of external rendering projects, including domestic and commercial properties, refurbishments and renovations and some timber frame projects. Depending on the product, they can offer applications a range of benefits:
- Wide Range of Colours: Some thin coat renders are available in a wide variety of colours, making it easier to achieve your desired finish.
- Thin Application: Provides a decorative finish without the thickness associated with some traditional render systems.
- Flexibility: Some silicone and acrylic render products offer better flexibility than more traditional materials, which may help reduce the risk of cracking.
- Water Repellency: Some thin coat renders offer water-repellent properties, providing additional protection to external walls.

What are the Different Types of Thin Coat Render?
There are different thin coat render types, with the most suitable option depending on the unique requirements of your project. Here is a brief overview of the options available.
Silicone Render
Silicone thin coat renders contain silicone resins and can offer a combination of flexibility and water-repellent properties. Depending on the product, they can be suitable for external applications where a durable and decorative finish is required. Some thin coat silicone renders can be useful for projects where exposure to the elements is an important consideration, including areas exposed to forestry (algae) or coastal areas (salt). The suitability of each product will vary, so always check the manufacturer’s guidance.
Acrylic Render
Acrylic thin coat renders contain acrylic resins and are available in a range of colours. Depending on the product, they can offer good flexibility that makes them suitable for a variety of external rendering applications.
Thin Coat Render Colours
Thin coat renders are available in a wide range of colours, with some products offering 150 options to choose from! This makes it easy for plasterers to find a suitable option for their project requirements.
It’s important not to forget colour bleed – when using a thin coat top coat, you need to ensure that the colour of the primer is the same shade as the top coat being used, as any missed top coat areas will back onto the primer instead of a grey backing/basecoat, for example.
Thin Coat Render vs Monocouche Render: What’s Best?
What’s best for your project: thin coat render or monocouche render? Both can provide a decorative finish for external walls, but they are different types of render that may be suited to different projects.
The right option will depend on factors such as the substrate, required finish and application. Here’s an overview of some of the key differences to help you find the right option for your project.
| Thin Coat Render | Monocouche Render | |
| Overview | A thin layered render system with a grain/stipple like finish with high weathering performance. | A mineral through-coloured render, generally applied in a thicker coat. |
| Key Features | Flexible, higher performing, extensive colour range. | Cost effective, quick drying times and a flatter more formal finish. |
