I have a table top I wish to varnish over and have bought some Ronseal
Diamond Hard Clear Satin (water based) Varnish.
I would like to get it on as *smoothly* as possible and not being too
brilliant wielding a paint brush wonder if, since it is a water based paint,
i could *dilute* it right down with boiled water and then more or less
'smear' it on using a rag, then turn up the central heating and hope that it
would all dry very smooth?
Another thought I had was to use a small roller. Our local store sells two
types of rollar surface, a sponge for gloss paint and a hairy one for
emulsion. If using a roller was a possibilty to get a very smooth surface,
which type of roller surface should I buy please?
Thanks for any advice with this.

I would not dilute it more than it states you can, but for a table you
might be better off with oil or a poly.

Be very careful adding water to water base products. Read the
directions carefully. Water based products are complicated blends,
and often have strict limits or prohibitions against adding water.
Even better, test it on the underside of the table. Thinning may or
may not have the desired effect. Some water base products will dry
faster if more water is added, locking in your wipe marks.
Personally, I'd seek out an oil based "wiping varnish", or make my own
by thinning a brush-on product to 60-70% varnish. A wiped on varnish
will probably need 5-7 coats on a table top. I'm not anti-water
base, I use 10-12 gallons a year of water based lacquer. I spray all
of my clear water based products.
You can remove any dust nibs with 400 grit paper and a wood or cork
sanding block. Some varnishes have a "window" where they can be
recoated without sanding, if you miss the window, you'll need to scuff
the surface with 400 grit or steel wool before the next wipe.
Yet another alternative is to brush on the finish, allow it to dry
thoroughly, sand it smooth, and rub it out to the desired gloss. This
takes a bit of learning and practice, but will probably yield the best
finish. Check your public library or local bookstore for Jeff
Jewitt's "Hand Applied Finishes." You can practice on the underside
of the table.
Be aware that if you stay with the water base, you need to protect
yourself. The primary selling points of water based finishes are
water cleanup and they aren't flammable. They ARE chemically
dangerous, sometimes containing more health hazards than solvent based
products. Ventilate well, better yet, spend the $30 for an organic
respirator. Water base does NOT equal safe to breathe.
Have fun, and practice where it won't be seen.

Dilute the first coat a bit. After it dries, sand lightly with 220 grit and
apply a second coat. Sand and a third coat. Sand with 320 grit and a
fourth coat. Let dry for two weeks or more. Now, wet sand lightly with
400, then 600 grit. Then xxxx steel wool, then pumice, then rottenstone.
Finally, paste wax.
Done right you have a smooth finish with depth that will rival any pro
finish around.

First just because a finish says that its water cleanup it doesn't
necessarily mean its water as its carrier.
Its an emulsion of many solvents that mix with water. The can will tell you
how much solvent you can add to a finish. I'm also confused why you think
you need boiled water and the rag will give the worst finish if it would
even work..
The best way to get a smooth finish is to use a foam brush and foam roller.
You will also need some 400 grit wet dry sand paper.
Assuming that your surface is sufficiently smooth.
You then can start by putting down two coats drying between coats. Then wet
sand the finish without cutting through to the wood. Wipe with a wet lint
free towel.
Then apply another coat, drying then sand. Repeat until you have at least 4
total coats.
