Respray in garage possible problem...

[25v6turbo]

As I mentioned in another thread I PLAN to maybe repaint my Dads Triumph in the near future in my home garage,but I have just noticed a potential and worrying issue,my house was built in the early 80s and still has its original boiler which is serviced and works fine,problem is the boiler is in the garage!,great for keeping it warmer than most garages,but its also maybe very dangerous if I was thinking about doing a full respray as there is a ignition starter and a flame in the boiler,so my worry is various amounts of thinners,paint, and paint dust in the air could or will cause issues including maybe something going BANG in a big way,i,am now thinking this is dangerous and may go to plan B,i,ve sprayed before and the dust is something else,i can see something catching alight on the boiler,thoughts please.

My thoughts are there is danger and if it was me just before the thinners got opened I would shut the boiler down and cover it up. I would then allow a bit of time for the fumes to clear before I restarted the boiler.

Just flicking on a light switch may cause a boom too ?  

[stonedagain]

Just turn off the electricity supply to the boiler once the garage has warmed up. After the car is painted, open the garage door to vent the fumes before turning the boiler back on.

I have done some spaying in my garage, I was helped by a friend with knowledge and experience and he made me shut off the free standing gas heater during spraying. Also he made me buy a decent fan fitted to the rear door to extract fume laden air from the garage. The back of our garage goes onto our garden and then a field but if you have neighbours this could be a problem. My feeling is without extraction you could never spray a whole car.

First thought is igniting flammable gases in an enclosed space rarely works out well for anyone in the immediate vicinity.

 

Second thought is do all the prep at home and get a pro to do the final spraying, although costs can be prohibitive, and

 

Third thought is to break out the brushes and rollers and hand paint the car. Time consuming but quiet and positively non-explodey

 

Or take as many panels off the car as you can and spray them in the garage - at least that will give you more room

This is plan B!

Have heard good and bad about rollering etc including the prep involved but also read about some good results,this maybe the plan...

[SiC]

What about going to a scrapyard to pick a few old bonnets up? Then have a go practicing with brushes/rollers before committing to the car.

[25v6turbo]

Yep was going to do exactly that have a practice,to be honest this could be the only answer,neighbours,noise,dust etc isn,t going to go down well in Devon!

Going to read aout rollering and what paints etc to use and take it from there,i,am worried about the boiler and the possible problems I could have.

Take a tip from the Jackal and spray it alfresco??.......

[DSdriver]

My experience of using a paint especially formulated for brush/roller was a disaster. I won a competition for materials to paint my yacht. I had three goes myself which all ended up in runs and sags so they sent one of their reps down to have a go with the same result. Next their top bloke came down with special brushes and thinners and again the same result. As you can imagine I was a bit pissed off because I was spending three days prepping each time and told them that I could have been at work and earned the money to pay for the boat to be sprayed professionally while all this faffing was going on. They eventually agreed that the boat was to be relaunched and taken to one of their spray centres who did a brilliant job with a two pack paint.

[Squire_Dawson]

Forgive me if I'm stating the obvious but, why not turn the main gas supply off?

[SiC]

I think with cars it requires a lot of post work to cut it back and polish to get a really good finish. If you roller paint I'd imagine you need even more work to clean it up.

[Parky]

Rustoleum paint or Tekaloid enamel. I think Vulgalour used Tekaloid for the purple sections of the Princess so would probably be able to provide a pointer or two

[vulgalour]

Yup, you can rescue even the shittiest roller job if you've enough paint to work with.  Do craploads of prep and read up on how to paint longboats/canal barges for the proper technique.  Buy the best brushes you can afford. Spend as much time as you can tolerate on prep... than a bit more.

And then, spend some more time on prep.

 

You cannot stress enough just how important prep is.

[steveo3002]

id time it until theyre out or on holiday or something ...or when the wind is blowing the smell away from them

 

yes some people have roller painted cars and they look great , many others have made a pigs ear of it

Where is that video from the 60's of some bloke that rebuilds a car in his garage and spray paints it with his Hoover?

[Parky]

When my Dad repainted his Renault 12 he would drive home on Friday, remove parts where possible, and bring them in the garden.

 

Whereupon the 12 year old me would help sand and prep them so they were clean-ish when he brought them into the house to paint them on the kitchen table!

 

We would then take turns with Mums hairdryer to assist with the drying process so they were dry enough to repaint or refit the next day. Sure it was embarrassing being taken to a posh school in a multi coloured car resembling something Onslow would drive but the overall effect was pretty good. So good in fact he never bothered with the final compounding (although on reflection that would have a reasonable job into a stunning one).

 

We didn't use rollers though, it was all brush work and the cellulose paint was relatively slow drying and forgiving. Enamel would have been better but the odour would have been a tad oppressive in the house and the drying time wouldn't have been particularly convenient.

 

An option anyway. A time consuming one, but a very cheap one.

Film is called "The Home Made Car". About 25 mins, dated 1963. Short bit of him paint-spraying using a hoover at about 16 mins 30.

The "cad" with the sports car went on to be, amongst other things, the guy who was one of the just-married gay hitch-hikers in the 1971 film "Vanishing Point".

 

Extract from Wiki, The Home Made Car -

"The film became a cult success when regularly broadcast as a trade test colour transmission on the run up to the start of BBC2 colour transmissions. Originally screened from September 1968 until August 1973, it was one of a series of short films broadcast to help television engineers set up new colour television sets".

Couple of thoughts about the boiler in the garage... is it a "room sealed" unit. The vast majority of boilers are, and you can tell, if it has both an air intake and exhaust outlet in the same through-the-wall tube, then it is room sealed, and it's no issue to have an explosive atmosphere in the garage: The inside of the boiler and the ignition/combustion is sealed and only connects to the outside.

 

.. and echoing the comments above, you will need extraction, or a decent fresh air supply. When I was a teenager, a friends father used to spray cars in his double garage, and used to get some pretty stunning results. He had a *very* clever system set up using a pair of largeish fans mounted in his roof, with some equally big filters, blowing filtered air into the garage from above. There were then a number of airbricks around the building at about 6" up from the ground, allowing the dusty/painty air out. This meant the paint vapour never got up around head-height, just blew away downwards.

 

The main benefit of the system was that any gaps and holes in the building allowed dirty air out rather than dusty air in, so he never had any specs of dust in his paint finishes. It was all lashed up with gaffer tape, cardboard, random cabling and good luck, but worked amazingly well.

 

... and if you set up ventilation, there's even less issue from the boiler, as the environment won't ever become explosive. A setup like that would even be acceptable for ATEX regulations.

Very helpful comments many thanks,my garage is partly built into the actual house so half of one side wall is my hallway and part of the rear garage wall is the side of my utility room,the garage is 11 high 9 foot wide and 17 foot long,it has an up/over garage door and a side door on the side wall near the rear,now what I have noticed is that if you have both doors open there is a good air flow which goes through the garge,not ideal as it could invite crap in the air,but I guess it would not build up with toxics etc so much,i can actually turn the boiler off and cover it up when cool,but I do plan to prep it all outside as it drives and do the hard sanding outside and the finer stuff in the garage,i do already have a compressor and gun etc,i have been reading about roller painting and as stated here it can turn into a bit of a mission and go wrong at the end,going to carry on researching and reading the helpful posts.

How about a marquee on the driveway?

I have done this a few times both using an electric earlex spray station

 

Here is one I did. Painted everything except the roof

You can spray a car in a garage.

Airflow is good but invites dust.

Our airflow dumped all the excess paint onto my neighbours Carp pond.

She and the fish were not amused.

[forddeliveryboy]

I knew of a car which had been painted outside on a drive, it was a superb finish in 2k without cutting back - as good or better than many pro jobs I've seen. Obviously the guy was practised and good - he reckoned April/May 8-10am on a still sunny day was the best time.

 

Using a cheap marquee would seem to make sense, with a dust sheet over the ground.

This guy does it, too. https://m.youtube.com/watch?v=DdQ65uNWbvk

 

Different video?

[vaughant]

When you go to paint it wet the floor with about an inch/half inch of water as that massively prevents dust getting under the paint/lacquer.
