Welcome to my review on the PaintWiz paint sprayer by Fuji. Every year sometime during April when the weather hopefully turns a bit warmer, I give the outside of the ‘shop’ a couple of coats. I use a wax based, weatherproof finish so that it’s got ample time to harden off over the long hot (!) summer. This year is no exception except that instead of using a large paintbrush I wanted to try out the Fuji PaintWIZ HVLP (High Volume Low Pressure) paint sprayer, suitable for paint, stain, varnish and many other products that you can be use around the home.
The simple set-up
Since never having used a paint sprayer of any sort, I was intrigued by the difficulty of setting up the machine. However, by studying the book of words inside the box, it all seemed pretty straightforward. The main element to consider is the viscosity of the liquid you will be spraying; which you can determine by using a special measuring cup, whereby it is timed when it runs out of a hole in the base. If it’s too thick, it won’t spray properly and is liable to cause spattering on the finished surface. If this happens, it should be slightly thinned following the advice usually found on the outside of the container.
There are two sprayer controls; the first is a rotary dial on the trigger which sets the volume of liquid you will spray. Turning the dial clockwise increases the volume and turning it in the opposite direction decreases the amount. There are three spray patterns to select by turning the air cap on the nozzle a quarter of a turn to the appropriate position; horizontal, vertical or circular.
When the viscosity of the liquid being sprayed is right, using the PaintWIZ presents no real problems but the user must carefully adhere to the instructions.
Once the spraying has been completed, the complete gun should be dismantled. All the separate parts must be individually cleaned in warm water or the appropriate cleaning solution. A solution of warm, soapy water should be sprayed through the reassembled gun and the exterior cleaned with a damp cloth. When using any sort of paint sprayer, it’s imperative to thoroughly clean all the component parts. Without this, the slightest trace of dried paint or stain will considerably impair its performance the next time it’s used.
Top tips for an even spray
The last section of the instruction manual contains a page on ‘troubleshooting’. It’s a relatively easy process to learn but producing a consistently good, even spray pattern is slightly trickier. If you’re struggling, this is where the final page is really useful!
