Spraying exterior paint

GAZ237

Be careful where you park your cars.

The builders were spray painting a house over 100 metres from where my car was parked.

Ended up with my car covered in paint spots and they had to pay to get a professional company in to clean it as it was all over the soft top.

Spraying it is an utterly barmy idea.

Purely IMO of course.

Can you say why?

The Beeny showed some woman a coloured spray on render that you never have to repaint.

Spraying does not fill the holes and crevices very well in block work

Ah, now that might be the flaw in the plan. Why doesn't it? I would have thought it would be better than a roller or a brush, and less damaging to the brushes.

Bit expensive for my old wreck though PN.:rotfl:

Four reasons two which I can see have been hightlighted already but for completeness:

1. You cover everything in the vicinity to a greater or less extent with paint spatter.

2. When you first paint any masonry surface (brick, block, pebbledash, spardash even plain smooth render) you need to use a brush to work the paint into all the little holes and crevices that are undoubtedly there. Even a roller won't fill them - well it would on smooth render). Yes you will wreck the brush.

3. If using masonry paint (which I presume you are) then you will have to thin it to a great extent so that it doesn't clog the sprayer. So perhaps 4 coats later via the sprayer what have you actually saved on time compared with two coats doing it conventionally (1 by brush followed by one by roller)?

4. When you work out how much paint you will waste (and have to clear up) spraying in the open air exposed to the slightest wind you will see that its a poor idea and cost you a lot more paint.

Not true, it depends on the type of paint used.With some pumps you can spray textured paints and even a type of plaster for walls. A pump will fill holes as good as any roller and if the holes are anything larger than about 8mm they would need filling first.

Airless pump is needed (very little overspray unless it blowing a gale). and not HVLP which sprays a very fine coat of paint with lots of overspray .
