Painting a large area of concrete block walls

[shivvy]

I would like to paint the inside of a shed to tidy it up a bit. I just need to do a quick, cheap and cheerful job. What is the best way to do it?
I have seen those paint sprayers advertised and wondered if they would be the right thing to use because I think it would take to long to do with a brush or roller. Plus I don't think I would go through as much paint.

All ideas gratefully received.

Thanks.

Shivvy - can you estimate how many Sq metres (or feet) you need to cover? - what is floor made of?

[shivvy]

Hi Tony. The floor is concrete and the room is approx 20ft x 30ft.

[TonyV]

sorry shivvy - meant to ask, what are you painting Wood, brick or wood? And you want it white I assume - do you need to do ceilling as well?

''what are you painting Wood, brick or wood?''

Tony... concrete block walls and the floor is concrete!

[shivvy]

lol snags!

Don't need to do the roof Tony. Can you suggest what would be my best option?

[TonyV]

Shivvy - some masonary paint with roller, with dust sheets on floor. Not worth buying/ hiring a sprayer. Your will need to brush down walls and seal before you start with finish coat. Not a cheap and chearful option, but will last. If you do want a cheap white finish - use trade emulusion, thin first coat by 20 - 50% to seal, then overcoat with neat paint till it's white enough and not showing patches.

Shivvy... B&Q are currently doing a cheap 'value' white emulsion if you decide to go with Tony's second option...

I guess it's fair-faced (unplastered) blockwork Shivvy. A 12-inch roller on a pole would be the quickest. Spraying would mean a whole lot of masking-up, and ........ rening a sprayer......... maybe use this..........

It could be getting knocked down next year Tony so as cheap and easy as possible is what I'm after.

[The Builder]

Go with Snags' paint then Shiv................ don't think I've ever seen paint so cheap :o)))))

[snags]

Or even cheaper... leave it as it is then and just remove the light bulb ;-p

[shivvy]

That paint from B&Q sounds like a good plan and I'm sure they do 12 inch rollers too - thanks snags.
What do you mean by 20 - 50% Tony?
Yes, it's unplastered Mr Builder so how much paint approx do you think I would need to buy?

[The Builder]

Tony means up to 50% water added for the first mist coat. Then one neat coat will do you. (This might alter with "shed" paints. They are often very thin to start with.)

[TonyV]

Shivvy - in trade it's called a misting coat - this will seal wall, will probably say on paint pot how much to thin it down - follow recommendations for painting new plaster

[The Builder]

Quantity depends on how well the first coat goes (suction etc). Maybe 40-50 litres?

[shivvy]

Brilliant - thanks for all your help guys.

No prizes for guessing how I will be spending this weekend!!

[TonyV]

What you doing after Saturday morning then?

[shivvy]

You are really funny - not!!

Thanks for all your help.

[TonyV]

Builder - Sounds a lot but I would have guessed 50 litres (5 tubs)
Shivvy cheap paint is like cheap anything - you get what you pay for and you will not enjoy finished product.
You could try this

not the best but certainly better than a "shed" own brand paint.
just depends how cheap you want to go?
