Silicone & Acrylic Finishes

Acrylic and silicone rendering are excellent exterior solutions for your home, providing a uniform textured coating that is breathable, flexible, and durable.

 

Acrylic rendering offers a wide range of colour options, while silicone render provides enhanced protection against sunlight and boasts self-cleaning properties.

At Dave Sung's Rendering Ltd, we specialize in both Silicone and Acrylic Renders. As showcased in our Residential Galleries, we have successfully transformed homes across Yorkshire and the UK, delivering exceptional results.

Serving clients throughout Yorkshire and nationwide, we provide Silicone and Acrylic Render solutions that ensure lasting quality and performance

Our External Rendering Process

Scaffolding Installation
To ensure full access to your property, we typically will arrange for scaffolding to be installed before work begins, collaborating only with reliable, professional companies to manage this process efficiently.

Protecting Your Property
Once scaffolding is in place, we take steps to safeguard your property. This includes taping up windows to protect the glass and frames from scratches or staining. Rainwater pipes are detached and, if necessary, redirected to prevent wash-offs during rendering. Waste pipes remain connected to the drainage system but are securely taped for protection. Additionally, driveways, patios, flagged areas, and gardens are fully sheeted to prevent any damage.

Surface Preparation
Any loose pre-existing render is removed using a hammer drill to expose the base. If the existing render is still solid, removing it may not be advisable due to the potential risk of destabilizing the brick or breeze block. In such cases, a keying technique is applied to improve adhesion for the scratch coat.

Applying the Scratch Coat
The surface is thoroughly brushed down to remove dust and debris before being hosed down if necessary. A 10mm layer of polymer render is then trowel-applied, incorporating a fiberglass reinforcement mesh for added strength. A 300mm x 300mm stress patch is placed at a 45-degree angle over corners of doors, windows, and openings to prevent cracking due to expansion or settlement. The scratch coat is the foundation of all our rendering systems, ensuring durability and long-term performance.

Beading & Joint Reinforcement
Plastic corner beads with fiberglass mesh are installed to windows, doors, and corners, ensuring sharp, defined edges. A bell cast bead (drip bead) is mechanically fixed along the damp course, and expansion beads are installed over vertical movement joints to reduce the risk of cracking from building movement.

Level Coat Application
A 5mm level coat is applied over the scratch coat and carefully troweled flat. Once partially set, a damp sponge float is used to smooth out trowel marks, creating an even surface for the final render. This coat is then left to dry and fully cure.

Primer Application
A silicone-based primer is applied using a roller. This improves adhesion for the final render while preventing the backing coat from absorbing moisture from the finish coat, making application more consistent and manageable.

Final Silicone/Acrylic Render Coat
The final coat, a silicone or acrylic-based render, is applied to the primed surface. Available in different textures (1mm, 1.5mm, 2mm, etc.), the most commonly chosen is 1.5mm. The render is trowel-applied and then scraped back to the selected thickness. A plastic float is then used in circular motions to achieve a uniform, textured finish, completing the rendering process.
