Product Spotlight: Unixil Render Finish Winter Formula
JUB Systems • October 27, 2021
Late autumn and winter is the most dreaded time of the year for many render applicators as temperatures drop and the chance of rain increases.
The unspoken rule of applying render is that it shouldn’t be installed at temperatures lower than 5℃ and increased humidity during the initial setting period. As humidity levels rise, it causes the render take significantly longer to dry and set. This can result in the render washing off and not being applied efficiently.
How to tackle high humidity and ever falling temperatures
JUB has established this as an issue and in order to help plasterers apply a smooth application of render in more restrictive weather conditions, we have manufactured a reinforced winter-grade topcoat.
The product can be applied in winter weather conditions where temperatures drop to +1℃ and humidity levels rise to 95%.
As with any of our high-quality render finishes, Unixil Winter Grade comes with many benefits:
- Rain resistant in 24 - 48 hours of application, dependent upon conditions/substrate
- Touch dry within 12 hours
- Easy to apply
- 90 minutes tub time
- Extensive range of colours with over 100 shades to choose from
- The same Siloxane resin quality associated with silicone renders
- Flexible and resistant to shrinkage cracking
- Uniform in colour and texture
- No requirement for any supplementary decorative coatings
- Long-term durability
What is the application process?
To ensure that Unixil Winter Grade is applied efficiently, we have prepared general guidelines to be adhered to.
Prior to the application, the preparation includes applying a base coat, which has to be dry before Unixil is applied. If installed onto a damp basecoat, this will overall prolong the drying time of the render finish.
Important: When mixing, do not add water to the Unixil additive or winter-grade topcoat.
The mixing should be as follows:
Add 1 full 500ml canister of Unixil Additive to one full 25 kg tub of Unixil Winter Grade.- Mix the contents of the tub at a high-speed setting with a drill whisk for at least 2 minutes to ensure that the Additive has fully integrated with the Unixil Winter Grade.
- Trowel on the Unixil Winter Grade as normal and texture with a plastic float as standard.
Pro Tip: You shouldn’t clean the plastic float in water in between texturing but clean with the trowel/spatula as the extra moisture will delay the drying process.
Unixil Winter Grade should be weather resistant within 24-48 hours of application, however, the system will still be curing behind the surface, therefore precautions should be taken not to damage or scratch the render until it has fully hardened.
Levels of humidity above 95% may cause a delay in the drying process.

Introducing the Great British Insulation Scheme, previously known as ECO+, a government initiative aimed at helping households insulate their homes, improve energy efficiency and reduce energy bills. With the scheme already launched and set to run until March 2026, it's time to discover how this £1 billion programme can benefit households across the UK. In this blog post, we'll delve into the details of the scheme, its eligibility criteria and the range of energy-saving measures available. Benefits of the Great British Insulation Scheme The Great British Insulation Scheme aims to support approximately 300,000 households by providing financial assistance for home insulation. By participating in the scheme, households can save an estimated £300 to £400 per year on their energy bills. The focus is on helping those with the lowest incomes, while also extending support to households living in energy-inefficient homes with Energy Performance Certificate (EPC) ratings of D or below, as well as those in lower Council Tax bands (A-D in England, A-E in Scotland and Wales). This inclusive approach ensures that more people, especially those struggling with high energy costs, can benefit from making their homes more energy efficient. The Aim of the Great British Insulation Scheme The Great British Insulation Scheme has a clear goal: to deliver single insulation measures to two main groups of customers. The first group consists of low-income individuals who do not meet the minimum requirements for ECO4 assistance. The scheme aims to provide them with valuable insulation measures to improve their living conditions. The second group includes households based on council tax band and Energy Performance Certificate (EPC) rating, targeting a wider range of individuals who can benefit from energy-saving upgrades.
Welcome to our guide on external render repair and maintenance. Whether you have a JUB render and/or an external wall insulation system, proper maintenance is essential to ensure longevity and visual appeal. By following our step-by-step instructions, you can reduce the need for extensive render repairs in the future, saving you both time and money. Let's dive into the key steps for effective render repair and maintenance. Step 1: Thorough Cleaning and Primer Application Before starting any redecoration work, it's crucial to clean the external render thoroughly. Remove any visible dirt or dust from the surface, ensuring a clean and smooth base for the upcoming paint application. If necessary, treat the facade with JUB Fungi Wash to eliminate any fungal growth or contaminants. However, avoid using acid-based cleaners or solvents, as they can damage the external wall insulation system. To enhance the adhesion and durability of the new paint, we highly recommend applying an appropriate paint primer to the cleaned render. Step 2: Choosing the Correct Paint Choosing the correct paint is crucial for achieving a long-lasting and visually pleasing exterior finish. Take into account the type of render you have and consult our technical department at technical@jub.org.uk for guidance on the suitable paint product. Avoid using masonry paint that JUB Systems UK Limited hasn't advised to maintain warranties and prevent short-term maintenance cycles. Keep the original render's colour code on file for future reference to ensure accurate colour matching.
Why Silicone Render is the Best Choice for a Property’s Exterior: Benefits, Application & Aesthetics
When it comes to a property's exterior, making a lasting impression with a beautiful and durable finish is key. That's where silicone render comes in. As a high-performance external render, it offers a multitude of benefits that make it the best choice for homeowners and renderers seeking long-lasting and visually appealing results. Benefits of Silicone Render: Why Choose It? Silicone render stands out for its numerous advantages. Firstly, it provides exceptional weather resistance, making it perfect for even the harshest climates. It can endure heavy rain, extreme temperatures and strong winds without cracking or fading. This ensures that a property maintains its stunning appearance for years to come. Another significant benefit is its breathability. By allowing moisture to escape through the walls of a property, it prevents the build-up of dampness and condensation. This is especially crucial for older houses and buildings with potentially inadequate insulation. By opting for silicone render, you can improve a property's energy efficiency and reduce the risk of dampness and mould. Flexibility is also a key feature of silicone render, setting it apart from traditional render systems. While other renders can be brittle and prone to cracking, silicone render is designed to move naturally with the property's walls, minimising the likelihood of unsightly fissures over time.
The ECO4 scheme has been helping eligible households in the UK to access free insulation and energy efficiency upgrades to reduce energy costs and support sustainable living. However, not all households that need support with improving their homes are receiving income-related benefits. That's why the UK government introduced the ECO Flex scheme. Under ECO Flex, local authorities are provided with more funding to identify residents who would benefit from home upgrades, even if they don't meet the standard eligibility criteria for ECO4. With ECO Flex, households don't have to be on benefits to qualify for funding. ECO Flex Eligibility The eligibility criteria for ECO Flex is quite comprehensive. To qualify, your Energy Performance Certificate (EPC) rating must be between E-G if you rent or D-G if you own your home. If your property is not currently on the EPC register, we can help assess it for you. You must also have a combined household income of less than £31,000. Alternatively, if you meet the EPC criteria, you can qualify for ECO Flex if you meet the following: Your home is within a specific postcode identified by your local council. You receive a council tax rebate (single-person occupancy excluded). You are identified as vulnerable to living in a cold home: someone in the home is pregnant, disabled or elderly, you have children under 5, or someone in the home has a medical condition. Your child receives free school meals. Your home is identified as being in debt to your energy provider. Another way to qualify is if you are identified by your GP as vulnerable to the cold and on a low income.
In an effort to reduce carbon emissions and increase properties’ EPC rating, the UK government has launched the ECO4 scheme, which aims to provide eligible households with free insulation and energy efficiency upgrades. Benefits of ECO4 The scheme is targeted at low-income households and those living in fuel poverty and is designed to help: Reduce Energy Bills: By providing eligible households with free insulation and energy efficiency upgrades, the scheme helps to reduce energy bills, making it easier for households to stay warm during the winter months. Improve Living Conditions: By installing insulation and energy efficiency measures, the scheme helps to make homes more comfortable, reduce noise levels and improve indoor air quality. Reduce Carbon Emissions: The scheme helps to reduce carbon emissions by promoting sustainable living and reducing energy consumption. This is an important step in creating a more sustainable future. Support Low-Income Households: The ECO4 scheme is designed to reduce the financial burden of heating and cooling a home and can improve the quality of life for those living in fuel poverty.
The Energy Company Obligation (ECO) is a government scheme that offers grant funding to support energy-inefficient homes, which in turn aims to reduce fuel poverty and carbon emissions. In this blog article, we’ll take you through all the details you need to know about the ECO funding scheme, what are the differences between ECO4, ECO+ and ECO4 Flex and do you qualify for free insulation grants. ECO: A Brief Overview ECO was developed for energy suppliers to financially support households across the UK with the aim of boosting the property’s energy efficiency and EPC rating. There are three sets of insulation grants available under the Energy Company Obligation: ECO4, ECO+ and ECO4 Flex. Each grant has its specific eligibility criteria but all of them offer the main types of energy-efficiency measures. These include loft insulation, cavity wall insulation, solid wall insulation and boiler replacement or repair. Can I Get Free Insulation? To qualify for the ECO insulation grants, you need to be the homeowner or have a signed document from your landlord granting you permission to apply. Eligibility criteria for each of the three grants vary and will depend on several factors. Here are some of the factors that if you meet, you will most likely be eligible for the grant to insulate your home: If you receive the Warm Home Discount in the 'core' group, get eligible benefits and fit the income requirements Live in social housing that has an EPC rating of E or lower (check your energy performance certificate, ask your landlord or social housing association or get in touch with an approved installer to find out ) You meet the criteria set by your Local Authority
