Professional spraying for metal and timber balustrades

Preparation differences for metal and timber substrates

The success of any spray project begins with substrate specific preparation, as metal and wood react differently to coatings. For metal balustrades, we focus on removing oxidation and contaminants that could prevent the primer from bonding. Timber balustrades require a different approach, involving detailed sanding and the application of blockers to prevent natural oils from affecting the finish. The goal is to create a stable surface that allows the atomized paint particles to form a continuous, smooth film.

• Abrasive cleaning of metal to remove rust and old coatings
• Fine sanding of timber for a smooth, splinter free surface
• Solvent wiping of all surfaces to remove grease and oils
• Detailed masking of surrounding areas to protect from overspray

Dealing with rust and failing previous coatings

Existing metal railings often suffer from corrosion, especially in coastal areas where salt air accelerates the breakdown of the paint film. We treat these areas with specialized rust converters to get back to sound metal before new coatings are applied. If the previous coating is thick or peeling, we may need to strip it back entirely to prevent the new spray finish from failing prematurely. For timber that has suffered from weathering, we ensure that any UV damaged fibers are sanded away.

Advanced primer systems for difficult substrates

Once the surfaces are prepared, we select a primer engineered for the specific material, such as high build zinc rich primers for steel. These primers are designed to be sprayed, allowing them to flow into the tightest joints and provide a complete seal against the elements. For metal, the primer provides an essential sacrificial layer that prevents rust from creeping under the paint. For timber, the primer fills the grain and provides a consistent base for the top coats.

• Use zinc rich primers for superior resistance on steel
• Apply stain blocking primers to prevent timber bleed
• Ensure even primer coverage in hard to reach details
• Lightly sand the primer for a perfectly smooth final coat

The benefits of site based spraying versus brushing

Spraying on site allows us to achieve a superior finish without the need to dismantle and transport large sections of balustrading. The speed of application is significantly higher than brushing, which reduces the time our team needs to be on your property. More importantly, the finish quality is unmatched, as there are no brush marks or uneven thickness across the rails. This is especially noticeable on modern, minimalist designs where a smooth, monolithic look is desired for the aesthetic.

Masking and containment in finished spaces

Because spraying involves atomized paint, the protection of the surrounding environment is our top priority. We use a comprehensive masking system, covering floors, walls, and nearby fixtures with specialized tapes to ensure that only the balustrade receives the paint. In indoor settings, we create a temporary containment zone using plastic sheeting and air extraction to manage any overspray. This meticulous approach means we can spray in fully finished homes or offices without leaving a trace of paint.

• Create a sealed environment to prevent paint mist spread
• Use high quality masking tapes that leave no residue
• Protect all adjacent surfaces with heavy duty polythene
• Employ air extraction systems to maintain a clean atmosphere

Refinishing existing powder coatings and coastal protection

Many modern metal balustrades are originally powder coated, a finish that is durable but can eventually fade or chip. We specialize in the on site refinishing of these surfaces, using high adhesion coatings designed to bond to the original powder coat. In coastal locations, we specify marine grade coating systems that offer enhanced resistance to salt spray and high UV levels. These advanced materials are designed to remain flexible and intact even in the most punishing weather conditions common here.
