The spray machines in this category are designed for EWI applications and can handle a wide range of render and basecoat blends, including lime-based, cementitious, acrylic, insulating, and flexible renders. This versatility makes them suitable for most façade finishes used in external wall insulation systems.

Spray machines offer significant benefits:

• Efficiency: Far quicker coverage over large areas, reducing project time.

• Consistency: Delivers even, uniform layers and minimises patchiness from manual work.

• Labour savings & safety: Requires fewer workers, reduces strain and allows operators to spray from a distance, lowering the risk of falls or repetitive strain.

Yes. To achieve the best results, operators should be trained in:

• Using correct machine settings and perfecting spray technique (e.g. spraying in small circles for uniform coverage).

• Proper nozzle and hopper maintenance to avoid clogs, e.g. tip-cleaning routines and using hopper liners.

Good maintenance helps avoid blockages and performance issues. Industry tips include:

• Fitting a bin-bag liner in the hopper to collect leftover material for easy disposal.

• Purging or spraying into a bucket at the start to clear clumpy material.

• Avoiding long pauses during spraying to prevent material drying and clogging within the nozzle.

• Scale of work: Machines are ideal for large façades or repeated use; not cost-effective for small patches.

• Budget: Upfront cost is significant—not just the machine, but also ongoing maintenance.

• Training requirement: Long-term savings and quality depend on experienced operators, so factor in training costs.
