Hi all,

I have been painting the master bedroom. I had scraped off flaky paint
back to bare brown plasterboard, polyfillered in the cracks and dents
with white filler. The old sound paintwork was sanded to give a flat and
keyed surface....

the bare plaster was primed with plaster sealer. the white polyfiller
sanded smooth..... walls then wiped down of the dust.....

I get the tins of emulsion out........

1st coat goes on..... very blotchy as expected
2nd coat goes on..... still blotchy
3rd coat goes on..... Can see where the bare plaster and the white
polyfiller
4th coat goes on..... White polyfiller gone but can see brown plaster in
5 places.

Will be putting on the fifth coat on tomorrow.

half the walls are being done in buttermilk which is not far off
magnolia and the other half in deep red

Both sets of walls similarly affected..... with paint prices being what
it is, this is getting expensive, i have got through 12.5 litres of
paint so far.

The artexed cieling was fine with just two coats of white emulsion.

For future room decorating, is there a base coat paint i can use that
will reduce the number of emulsion coats that I have to put on?

Stephen.

If you'd used a decent paint like a trade paint, you'd be finished by now,
but go on....

3rd coat goes on..... Can see where the bare plaster and the white

headache...

4th coat goes on..... White polyfiller gone but can see brown plaster
in 5 places.

one coat of normal paint, yes, using 'our mam's' , 'best in' or anything
with the word 'value' in the name is a definate no-no, as you have already
discovered. If you have been using quality paint already and got to this
dreadful situation, it boils down to the application, which begs the
question, have you been using a catapult?

Stephen.

What make of paint?

I usually find Dulux will cover pretty well in one with the 2nd coat being
perfect, no matter what the subtrate is - old paint, sealed plaster etc.

What paint?

Matt "Colours" by B & Q. In a rectangular plastic 2.5 litre tub


Application method?

Edges are done first with a brush and then a soft fluffy roller



Spreading to thin?

This is a room that is 4m by 4m by 2.4m high

B&Q's own paint is expensive crap, and they do nothing that you can't get
elsewhere.
Go to a trade paint outlet and take a sample of the colour you have chosen
and they will mix it for you, using quality bases

Sadly you have discovered B&Q own brand is rubbish.

You will generally not go wrong with any of the Dulux range IME.

That seems pretty normal - the way I do it.

On the plus side, it will not cost too much to go and buy some decent paint
;-o

Expensive "budget" paint. I paid £32.97 inc VAT for 5l Dulux Trade
Matt Emulsion from a Dulux Decorator Centre (so probably not the
cheapest source) the other day. Only a fiver more, for 5l, than the
B&Q stuff...

Application method?

Long or short pile? Rough would need a longer pile than smooth.

Spreading to thin?

This is a room that is 4m by 4m by 2.4m high

So less than 38m^2.

i have got through 12.5 litres of paint so far.

Hum if I found the right product on the B&Q site that should have
covered 112m^2 at it's lowest coverage rate of 9m^2/l, thats about 3
coats. So it doesn't appear you are brushing (rollering) it out too
much.

The highest coverage of the B&Q paint is quoted as 15m^2/l, FYI Dulux
Trade has a quoted coverage of 17m^2/l.

B&Q's own paint is expensive crap, and they do nothing that you can't get
elsewhere.

Not to disagree with that assessment but I have found myself using that
stuff myself in the past (SWMBO bought it!) and there was no particular
problem with applying it. She and my son did out son's bedroom here
last summer with it, and the usual one or two coats did a perfectly
reasonably job.

My point is that no way is the difference between B&Q paint and decent
stuff enough to account for the OP's disastrous results... my guess is
that if he applies a coat of Dulux now using the same tools/methods,
then the results won't be significantly different.

I'd have diagnosed it being spread too thinly or watered down or
something, but Dave L's calculations apparently give the lie to that
one. Bit of a mystery!
