Manual coating sprayer casings are made from either galvanised or stainless sheet steel, or plastic.

Sheet steel

Manual coating sprayers hand-held render tyrolean roughcast pebbledash Flickatex machine Sheet steel, comb and casing Sheet steel is often used to make the manual coating sprayer casing and the comb fingers as it can be easily shaped.

Manual coating sprayers hand-held render tyrolean roughcast pebbledash Flickatex machine Sheet steel thickness The sheets of steel used to make the casings and comb fingers are usually between 1.5mm (1/16″) and 2mm (5/64″) thick. Cheaper sprayers tend to be thinner, whereas the more expensive ones are thicker and therefore stronger and more hard wearing.
Manual coating sprayers hand-held render tyrolean roughcast pebbledash Flickatex machine Rusty steel bucket Sheet steel has a tendency to oxidise (rust) when it comes into contact with air and water. Manual coating sprayers are continually operated in wet conditions due to mixes used, and over time this can become a problem.

Stainless sheet steel

Stainless sheet steel is strong and resists oxidation (rust/corrosion) when immersed in water. It is therefore ideal for making manual coating sprayer casings that are so frequently subjected to these conditions.

Plastics

Manual coating sprayers hand-held render tyrolean roughcast pebbledash Flickatex machine Kettle - thermosetting plastic Manual coating sprayers with a plastic casing are also available. Plastics can be divided into two major categories:

Thermosetting plastics (thermosets)

Once cooled and hardened, these plastics retain their shape and cannot return to their original form. They are hard and durable and often used for automotive parts, aircraft parts, household goods and even tyres, amongst other things.

Thermoplastics

Less rigid than thermosets, thermoplastics can soften upon heating and return to their original form. They are easily moulded and extruded into films, fibres and packaging.

Plastic moulding

The plastic moulding forming the casing of the manual coating sprayer is a thermosetting plastic. This means that it is strong, rigid and light in weight.

Plastic manual coatings sprayers tend to be a more expensive option than the steel type due to their resistance to corrosion in all weathers and their bigger size and lightness compared to metal types with the advantage of covering large areas more quickly. They are aimed more for the professional.
