Brick rendering, the art of applying a protective and decorative layer over brickwork, has been a time-honoured technique to enhance the longevity and appearance of buildings. In today’s era, where do-it-yourself (DIY) projects are gaining immense popularity, many homeowners are tempted to take up the trowel and embark on brick-rendering adventures.
While the enthusiasm to take matters into our own hands is commendable, brick rendering is not just about slapping on some plaster. It’s a delicate craft with its own set of intricacies. The decision to DIY or hire a professional isn’t just about cost; it’s about ensuring the job is done correctly, preventing unnecessary mistakes, and achieving the desired result.
In this blog post, we’ll delve into some of the most common pitfalls in DIY brick rendering and explore why leaning on professionalism can sometimes make all the difference.
Common Mistakes in DIY Brick Rendering
Brick rendering can transform the appearance and durability of a structure. However, DIY attempts can sometimes lead to less-than-desirable outcomes. Below, we discuss some common mistakes DIY enthusiasts make during brick rendering projects and how to avoid them.
Poor Surface Preparation
Not cleaning the brick surface properly
The first step in rendering is ensuring that the brick surface is immaculate. Dust, grime, moss, or any other contaminants can hinder the adherence of the render, leading to a weak bond. Using a good brick cleaner and a stiff brush is essential. For tougher stains or growths, pressure washing might be a viable option. Yet, caution is required to avoid damaging the bricks.
Failing to fix cracks or damage before rendering
Rendering over damaged or cracked bricks is akin to building a house on a weak foundation. It might look good initially, but those imperfections will soon resurface, causing the rendering to crack or fall off. Always ensure all damage is fixed and the surface stable before rendering.
Incorrect Material Choice
The differences in rendering materials
From cement renders to lime and acrylic ones, a wide range of materials are available for brick rendering. Each type has its advantages and limitations. For instance, acrylic renders dry quickly and comes in various colours but might not be as durable as its cement counterparts.
Why some are unsuitable for certain brick types
Not all rendering materials suit all. For example, older bricks, which are softer, might benefit from a lime render due to their breathability, whereas modern bricks can handle the more rigid cement render.
Inappropriate Mixing of Rendering Materials
Importance of getting the right consistency
Achieving the right consistency is paramount. Too thick, and the mixture won’t spread evenly; too thin, and it may not adhere properly. Always follow manufacturer guidelines, and if in doubt, seek professional advice.
Risks of over or under-mixing
Over-mixing can introduce air bubbles, leading to a weaker finish. Under-mixing can result in an inconsistent mix, where some parts may be drier than others. This inconsistency can lead to uneven drying and reduced structural integrity.
Improper Application Techniques
Uneven thickness leading to potential cracks
One of the most common errors in DIY rendering is applying the mix unevenly. When some sections are thicker than others, it can lead to differential drying rates, resulting in cracks. Using a straight edge or darby helps in achieving a consistent thickness.
Failing to layer appropriately
Some rendering jobs require multiple layers, especially if aiming for a polished or particular finish. Hastily applying a single thick layer instead of multiple thin ones can lead to reduced adherence and a higher risk of cracking.
Not Taking Weather Conditions into Account
Rendering in too cold or hot temperatures
Temperature plays a vital role in drying. Extremely cold conditions can cause the render to freeze, whereas very hot conditions can lead to rapid drying, preventing proper curing.
Risks of drying too quickly or slowly
When render dries too quickly, it can lead to shrinkage cracks. On the other hand, when it dries too slowly (maybe due to high humidity), it can lead to a weakened bond with the brick surface.
Inadequate Protection Post-Application
Not allowing enough drying time
Patience is crucial. Rushing to paint or finish the rendered surface before it’s completely dry can compromise the outcome. Always refer to the manufacturer’s recommended drying times.
Failing to seal or protect the rendered surface
A protective sealant should be applied to guard against water infiltration and other environmental factors after drying. This step enhances the render’s longevity and maintains its aesthetic appeal.
Overlooking the Importance of Maintenance
Thinking it’s a one-time job
Rendering is durable but not indestructible. Homeowners often make the mistake of thinking that no further action is required once they render their bricks.
Ignoring the wear and tear
Like any other part of a house, rendered surfaces are subject to wear and tear. Regular checks for cracks, discolouration, or any other signs of damage, followed by timely repairs, can ensure that the rendered surface remains in top condition for years.
Benefits of Hiring a Professional
Proper understanding of materials and techniques
A seasoned professional brings years of experience and knowledge. They are well-versed in understanding the nuances of different rendering materials, how they interact with various brick types, and the best techniques for applying them.
Access to the latest tools and equipment
Like any other industry, brick rendering evolves with better tools and technologies. Professionals ensure they have access to the latest equipment, guaranteeing precision and efficiency that’s hard to achieve with typical DIY tools.
Saves Time and Money in the Long Run
Less likelihood of mistakes leading to redoing or repairs
A single misstep in a DIY project can lead to time-consuming and costly repairs. With their vast experience, professionals are less likely to make these mistakes, ensuring the job is done right the first time.
Professionals can often get materials at discounted rates
Owing to their industry connections and bulk buying capabilities, professionals can often secure materials at a lower cost, leading to overall savings for the homeowner.
Insurance and Guarantees
Peace of mind in case of unexpected issues
Professionals typically carry insurance that covers any accidental damages during the rendering process. This gives homeowners peace of mind, knowing that any unforeseen issues will be dealt with professionally without additional costs.
Warranty on the work performed
Many professional rendering services offer warranties on their work, assuring homeowners of the longevity and durability of the rendered surface.
Smooth, even finish
Achieving a flawless finish requires skill and expertise. Through their extensive training and experience, professionals can ensure a perfectly smooth and even render finish that’s often hard to achieve with DIY methods.
Better overall visual appeal
Professionals have an eye for aesthetics beyond the technicalities. They can advise on colour choices, finishes, and textures that complement the overall look and feel of the home, enhancing its curb appeal.
Choosing between a DIY approach and hiring a professional for brick rendering involves more than just evaluating the initial cost. It’s about understanding the long-term value in terms of durability and aesthetics. While DIY projects can be immensely satisfying, they come with challenges, especially in specialized tasks like brick rendering.
On the other hand, investing in a professional’s expertise guarantees precision, longevity, and an impeccable finish. When weighing the pros and cons, homeowners should consider the true value of professionalism and the peace of mind it brings, ensuring that their home remains a beautiful and sturdy sanctuary for years to come.
