The landscape of the British construction industry has undergone a significant transformation over the last two decades. Gone are the days when a simple sand and cement mix was the only viable option for finishing an exterior wall. Today, the market is dominated by sophisticated thin-coat systems that offer superior flexibility, breathability, and aesthetic appeal. One of the most significant hurdles for contractors working with these modern materials has always been the procurement of specific colours. Traditionally, ordering a coloured render meant waiting for a factory delivery that could take weeks to arrive on site. This delay often led to stalled projects and frustrated clients. However, the introduction of local topcoat tinting facilities has completely changed the game for plasterers and developers across the UK. By bringing the technology of the manufacturer directly into the local merchant, EJL Supplies ensures that professionals no longer have to compromise on speed or quality. This service allows for a level of agility that was previously impossible in the rendering trade.
Modern rendering projects demand a high level of customisation to meet the architectural visions of homeowners and commercial developers alike. Whether it is a crisp white finish for a contemporary new build or a bespoke earthy tone for a heritage renovation, the colour of the topcoat is the most visible aspect of the entire build. When a contractor has access to professional topcoat tinting facilities, they gain the ability to react to design changes in real time. This is particularly important in the UK where weather windows for rendering can be incredibly narrow. Having the ability to pick up a tinted product on the same day can be the difference between completing a project before a rain spell or having to wait another week for a dry day. The efficiency provided by this in-house technology is a primary reason why EJL Supplies has become a trusted partner for rendering professionals.
The Technical Precision of In-House Tinting for Jub and Fassa Bortolo
The process of tinting a topcoat is a highly technical endeavour that requires both advanced machinery and a deep understanding of the base materials. At EJL Supplies, the topcoat tinting facilities are specifically calibrated to handle the industry-leading products from Jub and Fassa Bortolo. These two brands are world-renowned for their chemical consistency and durability. The tinting process begins with a high-quality white or transparent base coat which is formulated to accept concentrated liquid pigments. Unlike traditional methods where pigments might be added by hand on a building site, the computerised systems used in the store ensure that every drop of colour is measured to a fraction of a gram. This level of precision is vital for ensuring that the final finish is uniform across every square metre of the elevation.
When working with Fassa Bortolo systems, such as their popular RX 561 or internal finishes, the tinting machine uses specific formulations that have been rigorously tested for UV stability. This means that the vibrant or subtle shade you choose today will remain consistent for years to come, despite the unpredictable British weather. Similarly, Jub’s silicone and acrylic renders are known for their high opacity and smooth application. The topcoat tinting facilities at EJL Supplies use the official Jubizol colour palettes, allowing for thousands of different shades to be produced on demand. This technical synergy between the manufacturer’s software and the merchant’s hardware guarantees that the product leaving the shop is identical in quality to a factory-mixed tub. It bridges the gap between the laboratory and the construction site, providing a level of reliability that manual mixing simply cannot replicate.
The importance of using official tinting pastes cannot be overstated in the professional rendering world. Some lower-quality merchants might attempt to use generic pigments in high-end renders, which can lead to streaks, fading, or even chemical failure of the render film. By investing in the specific topcoat tinting facilities recommended by Jub and Fassa Bortolo, EJL Supplies protects the integrity of the contractor’s work. This commitment to quality ensures that the manufacturer’s warranty remains intact, providing peace of mind for both the installer and the property owner. The software within these machines also stores a digital record of every mix, which means that if a project requires more material later, the exact same shade can be reproduced with perfect accuracy.

Eliminating Lead Times and Improving Site Productivity
In the fast-paced world of construction, time is quite literally money. One of the most significant drains on a plastering company’s profitability is “dead time” spent waiting for materials to arrive. Before the availability of local topcoat tinting facilities, a contractor might find themselves short by two or three tubs of coloured render near the end of a job. Ordering those extra tubs from a central factory could take five to ten working days, leaving the scaffolding up and the project unfinished. With the in-house service provided by EJL Supplies, that same contractor can simply drive to the store and have the extra tubs tinted and ready within minutes. This immediate turnaround keeps the workflow moving and allows the scaffolding to be dropped sooner, which significantly reduces the overall cost of the project.
Furthermore, the ability to obtain tinted renders locally allows for much better inventory management. Instead of over-ordering materials to avoid the risk of running out, contractors can buy exactly what they need for the initial phase of the work. They know that the topcoat tinting facilities are always available if they need to top up their supplies. This reduces the amount of capital tied up in excess stock and minimises the risk of material going out of date in a storage unit. It also allows for greater flexibility when a client changes their mind about a colour choice at the eleventh hour. Rather than being stuck with a pallet of factory-ordered render that is the wrong shade, the contractor can wait until the final decision is made before having the topcoat tinted to the exact specification.
Productivity on site is also improved by the consistency of the material. Because the topcoat tinting facilities ensure a perfect mix every time, there is no need for the installers to spend time trying to blend different batches or worrying about “picture framing” on the walls. The render is ready to be applied straight from the tub with full confidence in its performance. This allows the team to focus on their craftsmanship and the quality of the finish rather than the chemistry of the product. For a busy rendering firm, this reliability is an asset that helps build a reputation for quality and punctuality. EJL Supplies understands these pressures because the company was founded by individuals who have spent years on the tools themselves.
Technical Benefits of Silicone and Acrylic Topcoats
When discussing the output of modern topcoat tinting facilities, it is important to understand the different types of renders being processed. The two most common options are silicone-based and acrylic-based topcoats. Silicone renders have become the gold standard in the UK due to their exceptional breathability and self-cleaning properties. These products allow water vapour to escape from the building structure while preventing liquid water from penetrating the surface. When a silicone render is tinted using professional equipment, the pigments are suspended in a way that does not compromise these hydrophobic qualities. This ensures that the building remains dry and protected while looking aesthetically pleasing in its chosen colour.
Acrylic renders, on the other hand, are prized for their high levels of flexibility and impact resistance. They are often the preferred choice for areas that might be subject to more movement or where a particularly vibrant colour is required. The topcoat tinting facilities at EJL Supplies are adept at handling these high-resin products, ensuring that the colour is deeply integrated into the material. Because acrylics are less breathable than silicone, they are often used in specific systems where a high-strength, waterproof finish is the priority. Understanding these technical nuances is part of the service provided by the team at EJL Supplies, who can advise on which tinted product is best for the specific substrate and environmental conditions of the project.
Another technical consideration is the “Light Reflectance Value” or LRV of the chosen colour. Darker colours absorb more solar heat, which can cause thermal stress and potential cracking in some rendering systems. The advanced software used in our topcoat tinting facilities provides instant feedback on the LRV of a chosen shade. This allows the staff to warn a contractor if a colour might be too dark for a particular insulation system, such as External Wall Insulation (EWI). This level of technical oversight prevents costly failures down the line and ensures that the finished facade is not only beautiful but also structurally sound and durable. This expert guidance is what separates a specialist merchant from a general building supplier.
Precision Colour Matching and Aesthetic Consistency
For any large-scale rendering project, aesthetic consistency is the primary measure of success. Nothing ruins the look of a new building quite like a visible “tide mark” where two different batches of render meet. The precision offered by local topcoat tinting facilities is the best defence against this issue. By using the same machine and the same base batches, EJL Supplies can ensure that the colour remains identical from the first tub to the last. This is especially important for multi-plot developments where several houses need to look identical. The digital nature of the tinting process means that the “recipe” for a specific project is saved and can be recalled at any time, ensuring total continuity.
In addition to standard colour charts, the ability to provide custom shades is a major advantage. While brands like Jub and Fassa Bortolo offer extensive standard ranges, some projects require a specific match to existing masonry or local stone. The topcoat tinting facilities can often be used to create these custom blends, giving architects and designers almost limitless creative freedom. This capability is particularly useful for renovation projects in conservation areas where the new render must blend seamlessly with the surrounding historical environment. The experts at EJL Supplies can work with contractors to find the perfect match that satisfies both the client and the local planning authorities.
Aesthetic consistency also extends to the texture of the finish. Whether a project requires a 1.0mm, 1.5mm, or 2.0mm grain size, the tinting process remains consistent. The pigments are thoroughly dispersed throughout the textured aggregate, ensuring that the colour is through-and-through. This means that if the surface is ever lightly scratched, the colour underneath is the same as the surface, making the damage much less noticeable. The topcoat tinting facilities are designed to handle these various grain sizes without clogging or losing accuracy, providing a professional finish every time. This attention to detail is what allows EJL Supplies to support the highest standards of workmanship in the plastering industry.
