Brush-on product to seal concrete sills

Owatrol oil will also do the same thing.
Can be got in most diy stores

Polybond surely does the job ?

Can be applied neat on window sills as a primer for oil or waterbased paint.
I can't link for my phone but a quick Google seach will verify same.

Here you go,

http://www.albany.ie/?page_id=577

▼ Tip: Sealing Stone, Brick, Wood ,etc.
Apply Owatrol Oil with a brush, roller or spray.
Wipe off any excess that does not penetrate to avoid shiners or ponding.
Add some VC175 to prevent mould, algae etc.

▼Tip: Paint Flaking off Facias, Sills etc. (When using Oil Based Paint)
After removing all the loose stuff, mix about 30% Owatrol Oil into your first coat and apply. This will give massive penetration and bonds the paint tightly. Add up to 20% of Owatrol Oil into subsequent coat(s) for a superb finish that will not peel or flake off.

And from here,

http://www.igoe.ie/download/Owatrol-The-Legend-2013.pdf

Makes Oil Based Paint Or Varnish Stick Like Glue – No Peeling or Flaking.
Any surface that has a history of peeling paint or varnish or will potentially throw off the
paint can be successfully painted with outstanding long lasting results. Most common
examples would be[/B] window sills[/B], wall or pillar cappings, fascia boards, sun facing
doors and windows, garden ornaments, galvanised steel railings, gates, dusty concrete
floors etc.
Some examples of this application as follows:
A concrete floor which raises clouds of dust when swept can be
stained any colour you like thereby sealing in all the dust and
obtaining a lovely hard wearing, painted, dust-free floor at the
same time. (Not appropriate for forklift traffic etc)
The same can be done on concrete
patio slabs, garden ornaments,
brickwork, roof tiles,

That should keep you going ;)

NO, no, no. Polybond is not a waterproofer.

Google Parex "Paraguard AG". Supposed to be a very invisible good acrylic sealer.
