Selecting the right render supplies is crucial for achieving a durable, attractive finish on your property’s exterior. Whether you’re embarking on a new build or renovating an existing structure, understanding the various render systems and materials available is essential. This comprehensive guide will help you navigate the world of render supplies, ensuring you make informed decisions for your project.
Understanding External Render Systems
External render systems are designed to protect and enhance the appearance of buildings. These systems typically consist of multiple layers, each serving a specific purpose. The main components of an external render system include:
- Base coat
- Reinforcement mesh
- Primer
- Top coat
When choosing render supplies, it’s important to consider the specific requirements of your project, such as the substrate type, climate conditions, and desired aesthetic outcome.
Exploring Different Types of Render
There are several types of render available, each with its own unique properties and benefits. Some of the most popular options include:
Silicone Render
Silicone render is a modern, high-performance option that offers excellent water repellency and breathability. It’s known for its durability and low maintenance requirements, making it an increasingly popular choice for both residential and commercial projects.
Key features of silicone render include:
- Excellent weather resistance
- Self-cleaning properties
- Flexibility to accommodate building movement
- Wide range of colour options
Insulated Render
Insulated render, also known as external wall insulation (EWI), combines rendering with insulation to improve a building’s thermal performance. This system is particularly beneficial for older properties or those with solid walls.
Benefits of insulated render include:
- Enhanced energy efficiency
- Reduced heating costs
- Improved internal comfort
- Protection against damp and condensation
Sand and Cement Render
Traditional sand and cement render is a cost-effective option that has been used for centuries. While it may require more maintenance than modern alternatives, it remains a popular choice for many projects.
Advantages of sand and cement render:
- Economical
- Suitable for a wide range of substrates
- Can be painted or left as a natural finish
- Familiar to most tradespeople
Selecting the Right Render Supplies for Your Project
When choosing render supplies, consider the following factors:
Substrate Compatibility
Ensure that the render system you select is compatible with the substrate of your building. Different renders work best with specific materials such as brick, block, or timber frame construction.
Climate Considerations
The local climate plays a significant role in determining the most suitable render system. For areas with high rainfall or extreme temperature fluctuations, a more durable and flexible render like silicone may be preferable.
Aesthetic Requirements
Consider the desired appearance of your finished project. Render supplies are available in a wide range of colours and textures, allowing you to achieve the perfect look for your property.
Essential Render Supplies and Accessories
In addition to the render itself, several other supplies and accessories are crucial for a successful rendering project:
Render Bead Adhesive
Render bead adhesive is used to secure beading and trims in place before applying the render. This ensures clean, straight edges and helps protect vulnerable areas of the building.
Render Board
Render carrier boards, also known as cement render boards or external render boards, provide a stable surface for applying render. These boards are particularly useful when rendering onto timber frame constructions or areas where the existing substrate is unsuitable for direct application.
Render Panel
Render panels are pre-fabricated sections that can be used to create decorative features or to cover large areas quickly. They are often used in conjunction with traditional rendering techniques to achieve a desired aesthetic.
Choosing the Right Render Colours
Selecting the perfect colour for your rendered exterior is a crucial decision that can significantly impact your property’s appearance. Consider the following when choosing render colours:
Rendered Exterior House Colours
Popular house render colours include neutral tones such as white, cream, and grey. These colours offer a timeless appeal and can help your property blend seamlessly with its surroundings.
External Render Colours
For those looking to make a bold statement, vibrant external render colours are available. However, it’s important to consider the long-term implications of your colour choice, as repainting a rendered surface can be a significant undertaking.
Render Colour Chart
Most render manufacturers provide a render colour chart to help you visualise different options. It’s advisable to view physical samples in natural light before making a final decision, as colours can appear different on screen or in print.
Understanding Render Application Techniques
Proper application is crucial for achieving a high-quality render finish. Key techniques and considerations include:
Scratch Coat
The scratch coat, also known as the render scratch coat, is the first layer applied to the substrate. This layer provides a key for subsequent coats and helps even out any irregularities in the surface.
Render Scratch Coat Mix
The render scratch coat mix typically consists of sand, cement, and water. The exact proportions may vary depending on the specific requirements of your project and the render system being used.
Silicone Top Coat Render
For silicone render systems, the top coat is a crucial component that provides the final colour and texture. Silicone top coat render offers excellent water repellency and durability, making it a popular choice for many projects.
Waterproof Render Solutions
In areas prone to damp or where additional protection is required, waterproof render can be an excellent solution.
Waterproof Render for External Walls
Waterproof render for external walls helps protect the building fabric from moisture ingress, reducing the risk of damp-related issues. This type of render is particularly beneficial in coastal areas or regions with high rainfall.
Silicone-Based Render
Silicone-based render offers inherent water-repellent properties, making it an excellent choice for projects requiring enhanced protection against moisture. This type of render also allows the building to breathe, reducing the risk of trapped moisture within the walls.
Choosing Render Suppliers
Selecting the right render supplier is crucial for ensuring you receive high-quality products and expert advice. Consider the following when choosing a supplier:
- Range of products available
- Technical support and advice
- Delivery options and lead times
- Warranties and guarantees
- Customer reviews and testimonials
Some reputable render suppliers in the UK include K Rend, Johnstone’s Trade, and PRB Systems. It’s advisable to research multiple suppliers and compare their offerings before making a decision.
