UK-Based Specialists in Render & K Render Painting
APT ICC provides specialist render and K render painting services across England and Wales for commercial, residential, and public-facing buildings. This service focuses on the correct cleaning, preparation, and repainting of rendered façades to improve appearance while protecting the integrity of the surface.
Render and K render painting is commonly required when buildings become stained, faded, or uneven due to algae growth, pollution, weather exposure, or previous coating failure. The service is sometimes referred to as rendered façade painting or external render coating. While the terminology varies, the objective remains the same: to restore a consistent finish and provide long-term protection suited to the specific render system.
APT ICC works with all common render types, including traditional render and modern K render systems. Each building is assessed in advance to determine whether a breathable or non-breathable coating is required, depending on the substrate, existing finish, and building construction. This assessment-led approach ensures moisture is managed correctly and prevents future issues such as blistering, cracking, or trapped damp.
Works typically include careful cleaning to remove algae, dirt, and surface contamination, followed by appropriate preparation before painting begins. The process is tailored to suit live environments such as offices, cinemas, apartment blocks, shops, and commercial premises, with access and safety controls planned to minimise disruption.
With over 35 years of experience, APT ICC is trusted to deliver render and K render painting on a wide range of building types. Recent projects include render painting works at Acrow offices in Gloucester. All services are delivered under strict health, safety, and environmental controls, providing durable, high-quality results across England and Wales.
“I would like to express my sincere thanks to APT for the excellent job they carried out at Tai Bach. The project was a much needed one and now that it is completed it has really helped to improve the look of the town. We have received many good comments from the public which is always a good sign.”
Kevin Hiller - Property Surveyor, Neath & Port Talbot Council
“We employed the services of APT to renovate a Grade 2 Listed Building. Under the directive of Cadw we were not allowed to use any wet process or chemicals within the interior of the building. APT used Soda Blasting on sandstone, brick, ceramic glazed tiles, metal work, paintwork on ceilings, coving, woodwork and ornate fixtures.
It was a great achievement to have one system for all the surfaces that needed cleaning and restoring and one that also ticked all the boxes of the environmental and conservation officers. The process saved us both time & money in being able to have just one company on site. We are very grateful to APT for their hard work on this project.”
Tim Luke - Gee Construction
“I would like to thank APT-ICC for their excellent work and assistance on the Barclays Bank project. They delivered the scheme and additional works on time and without issue thanks to Andrew and his team for all your extra effort, long hours and commitment. I look forward to using them on future renovations.”
Graham Lowe - Project Manager, Overbury Plc
“We have been receiving an overwhelming number of positive comments about the war memorial cleaning. Yesterday, during the small ceremony at the Penrallt column on the 1st World War anniversary, many expressed their appreciation for how splendid the memorial looks after the cleaning. We anticipate sharing photos on the internet page later this week. Additionally, we have shared your details with another person who serves as the clerk to two other local councils. Thank you once again for the exceptional work.”
Janice Davies - Gwynedd Council
Render and K render painting involves cleaning the surface, preparing it correctly, and applying suitable coatings. The aim is to restore appearance while protecting the render from weathering and staining. Preparation is essential to achieve an even, long-lasting finish.
Over time, render can become stained, faded, or patchy due to algae, pollution, and weather exposure. Repainting helps restore a consistent appearance and prevents further deterioration. It also helps control future staining and growth.
Yes, render and K render require specific preparation and coatings. Incorrect products or methods can trap moisture or cause peeling. Each surface is assessed to ensure the correct system is used.
In many cases, yes. Work is planned to manage access, safety, and disruption around staff, tenants, or visitors. This makes it suitable for offices, shops, and other live environments.
Often, yes. Painting can extend the life of existing render and improve appearance without the cost of replacement. An assessment is needed to confirm the render is suitable for painting.
Small, low-risk areas may be manageable internally. Larger façades, high-level work, or specialist render systems usually require professional experience. Incorrect painting can lead to long-term surface issues.
Lifespan depends on surface condition, exposure, and the coating used. Proper preparation and suitable products significantly extend performance. Planned maintenance helps keep the finish looking consistent.
APT ICC delivers render and K render painting services across England and Wales. We work on commercial and public-facing buildings and can also advise on suitable coatings and surface treatments where full painting services are not required.
