Painting large models

[Gareth JonesParticipant @garethjones79649]

My wife and I share a workshop which was created by converting about 70% of the length of our garage. The end nearest the up and over door is used for storing a few large boat boxes, a couple of Workmates, the lawnmower and a few garden tools. We normally use this end space for painting models, either with the door open or closed.

At the moment Elizabeth is restoring a 10 rater for a chap in Derby. The hull is just under 6 feet long and too big to paint in the end of the garage. It was primed outside a few weeks ago but working outside is very weather dependent, needing a calm warm day, which seem to be few and far between, particularly in winter.

The workshop would be big enough but we don't want paint drifting everywhere. This is a recurring problem and we have been considering various options ranging from extending the garage to buying a gazebo. However another idea occurred to me couple of weeks ago and I went out and bought a couple of heavy duty dust sheets from Screwfix. These have been hung from the ceiling using large screw hooks at 3 foot intervals, in conjunction with eyelets in the dust sheets.

The system has had its first trial tonight and seems to work very well. The sheets are hung behind the lights so the illumination is good and even. One of the problems of working in the end of the garage in daylight is the contrast between the inside facing and outside facing parts of a model, especially in bright sunlight. At the moment ventilation is only by opening the internal and up and over doors but I plan to improvise something using the dust extractor we use for the scroll saw and disc sander. Here are a few pictures of the paint shop in action.

The 'Workmate' in use is the JCB variety and comes in very useful for jobs like this because it can be set to a wide range of working heights.

Gareth,

I found this very interesting reading indeed, as I have recently been thinking a fair bit about how to set up my new workshop after we move, including a dedicated painting area. As I've already mentioned, I think, we shall rent, so I want to avoid as far as possible making any holes or similar in walls or ceilings that cannot simply be filled in and repainted when we move out again in ten years or so.

Given that the basement where the workshop will be is all raw concrete or cinder blocks, that I am thus loath to make holes in, I am inclined to get a couple of Ivar shelving sections from IKEA (**LINK**), join them together across a suitable width of floor with wood lattices to create a sort of openish cage, and then cover the whole thing in heavy-duty plastic dust sheets or similar. For a door, a shower curtain ought to do, and then I was thinking I might put up a number of LED strips from the same source (**LINK**), both on the shelving sections and overhead. Up to ten of those can be connected up, and at 340 lumen each, a sufficient number should provide a both strong and even enough source of light for painting. And because they're LED, they should neither generate much heat nor make too large an inroad into the electricity budget …

Given the amount of very intrusive paint dust from airbrush or spray can painting, I am also thinking about getting one of these: **LINK**. While much to small for car body painting or similar full scale spray paint fumes and dust production, I think it should be perfectly adequate for airbrush work, which is after all my main way of painting.

Well, time will tell, but in the meantime, thank you very much for a most inspiring post!

I have made a paint booth from a very large moving box, 2 feet square x 5 feet tall (a "dish pack" they are called over here). I cut one side out of the box, then cut a square hole in the opposite side to fit a house air filter. A box fan is attached outside the box over the filter, so it sucks air through the filter and the box. I have painted my Loyal Fleet Tender (40" LOA) in it and never had paint escape into my garage. Paint does not show on the fan blades, so the filter is very effective.

I would post a picture of my booth, but I am new to this forum and don't know how.

The paintshop has been tried out three times now with Elizabeth's 10 rater project getting a coat of white, followed by a coat of blue and today some lacquer. After the first trial which was without any forced ventilation we have run the dust extractor with the suction hose poking out into the spray area and it is reasonably effective. The lighting was good but spraying the lacquer was less successful as it was difficult to see how much was applied with the result that there were a few runs. Prior to lacquering the yachts name was added using Crafty Computer paper's clear transfer paper, printed using Word and an inkjet printer. Here are a couple of pictures showing the result, the first is directly after applying the navy blue to the hull bottom.

The second is after the hull had been rubbed down and the name applied, prior to lacquering.

Conclusions so far are that the curtain idea is a viable option and there is minimal drifting of paint behind the hanging dust sheets. However lighting could be better, and I am not sure what I can do about that other than a radical change to the workshop lighting. Ventilation is tolerable with the dust extractor going and the door open for a quick escape afterwards. Elizabeth says she is never doing another yacht this big as a restoration project for someone else.
