Tips on using decorator’s caulk
Decorator’s caulk is a flexible filler that can be used to go around windows, doors, ceiling and coving line and along the top of skirting boards. It isn’t any good for filling holes in walls etc, as it cannot be rubbed down like powder filler.

To get the best results from using decorators caulk run it along the crack, not too much (you can always go over it again), once you have a line of caulk use a wet finger to run along the line of caulk to smooth it over.

Once the caulk has dried it can be painted over. If you find once you have painted the caulk with emulsion it cracks, you can go over the caulk with an oil-based undercoat, let it dry, then re-emulsion the caulk.


I have done a review on a caulk that doesn’t crack or craze, I have been using it for a while and the results are good.

    Thought that caulking would be similar to what ever I needed to fill .¬!! This time I made a mistake ,probably rectifiable

    but am now worried that the stuff will not accept Paint or anything else .
    I have watched a professional painter do his work with caulk , and not a word was mentioned as to the suitability of the acrylic to accept paint ,or was he keeping it a secret ??very annoyed about this as it has taken me hours to put right a
    simple job !!!
