A few years ago we had to have builders in to do some jobs in the house.
We have now found that some of the wood they have used was not treated and
that brown rings, probably from knots in the wood are showing through the
paint.
Please can anyone advise how to get without these?
Many thanks
John

As already posted, a coat of shellac.
Why do you think the wood should have been treated and what do you mean
by treated?

Use the product Kilz. It is a white primer.
My experience with Kilz is to apply two coats of Kilz (drying between coats)
over areas with knots.

Does this primer come with shellac in it? If it is, I've used a similar
product and have had the knots still bleed through after year even with two
coats on the knots.

An old method for stubborn knots is to paint them with aluminum paint, the
type with aluminum particles in it, the aluminum blocks the resin and stain
from pushing through the paint. Of course, aluminum paint being dark may
have its own issues about covering it.
Ultimate would be to use both methods, the aluminum paint covered with a
couple of coats of shellac or KILZ.

Shellac has been the solution for years because it is not dissolved by the
nonpolar chemicals which compose the resin, but with a (semi) polar solvent.
The film doesn't soften, or as is the case with latex, lift. You want to
get some pounds in the cut, though. Perforated films allow seep and lift.

Put a coat of shellac over the knots and then paint.
