Testing out the Wagner SpeedShield “pizza wheel”

We had a Spray & Play Day a few days go and our guests really really wanted to try out the Wagner SpeedShield, also know as the Wagner “pizza roller”. Here you can have a glimpse of what we did.

What is the Wagner SpeedShield “pizza wheel” and how does it work?

The Wagner SpeedShield consists of a swivel joint with TradeTip 3 tip guard and a disc-shaped wheel, similar to a pizza cutter. The system is mounted on a lance and the wheel serves as protection to form a boundary between the area to be sprayed with paint and the rest. This should make it possible to paint surfaces next to door frames or floor strips quickly and without masking.

The package includes a swivel joint, a tip guard and a wheel. lances and the nozzles must be purchased additionally.

Our test

We tested the Wagner Speedshield with a powerful electric piston pump. We used a 50-cm lance and Wagner as well as FARBMAX spray tips. The material was Relius Volldecker 4XFF, diluted.

Impressions from the test of the Wagner Speedshield

Nozzle size – recommendation in the product description

The manufacturer recommends 411, 511, 513 and 615 as tip sizes. A bit small for indoor emulsion. At least with the paints here in Germany, many indoor emulsion paints can not be sprayed with nozzles this small and would clog the nozzles immediately. What we must assume is that the SpeedShield was probably originally developed for the US market. The sort of materials used there differ significantly from European or German products and are often thinner. The product description was apparently just taken over.

That’s why we had to dilute Relius Full Coater 4XFF, so that this material could be sprayed with a 0.013″ nozzle. With thicker paints it can quickly come to problems and clogs. Therefore, pay extra attention to your material when your using this SpeedShield.

Set the correct angle between pizza wheel and nozzle

The joint must be set to the correct angle between the wheel and the nozzle. In the optimum setting, the wheel should be hit slightly by the spray jet coming from the nozzle, but only slightly. Otherwise too much paint lands on the pizza wheel and the wheel must be cleaned very often.

Cleaning the wheel on the Wagner Speedshield

The wheel must be cleaned regularly anyway, otherwise the paint would simply drip down or could dirty the surface you want to spray. The cleaning can easily be done with a rag. The paint is simply wiped off the wheel. After use, the pizza wheel can be easily cleaned with water.

Line with the Wagner Speedshield

Unfortunately, in our test the lines were not as sharp as we hoped. The picture shows a particularly strong case from the beginning of the test. The paint was quite thick here, and we were using already a rather small 0.013″ as a spray tip. An even smaller nozzle would have led to clogs and blocking of the nozzle. So when we continued spraying, we trying to compensate by increasing the spraying speed, in order to reduce the order quantity of material. This improved the lines.

Special features of a lance with the SpeedShield

The use of lances can cause splashing and spitting. More about this in this article: Prevent spit effects and splashes – anti-spitting valves. Since the pizza wheel is generally used with a lance, this problem can also occur pretty often here. However, certain working techniques or the use of anti-spit valves can minimize or completely eliminate this effect.

This effect is due to the use of the lance and does not happened because of the Speedshield.
