Find responses to frequently asked questions in the following categories
Q. Should I prime before filling?
A. We recommend priming before and after application of the filler. Priming will protect and aid with adhesion of the filler to the surface. Priming afterwards also ensures excellent adhesion of your paint top coat.
Q. What sand paper is best to use on filler?
A. Start off with a low grit such as 80-120 to move the majority of the filler, you can then use a high grit like 180-240 to smooth off to an even finish.
Q. Can I add water to a Polyfilla ready to use filler to make it flow more smoothly?
A. No, this will decrease the filling ability of the product. If the product seems too firm, manipulate the tube with your hands before use - this will soften it up.
Q. Can I lengthen the working time of Polyfilla Powder Fillers?
A. You can maximise working time by ensuring that all tools and mixing containers are clean, as traces of old filler shorten working time.
Q. Can I speed up the paint stripper process?
A. Yes, by lightly scouring the surface of the coating with a stiff wire brush or by lightly sanding the surface with a coarse-grade sandpaper before application of the stripper. Placing a garbage bag over the item being stripped will also help reduce paint stripper evaporation and will result in more effective stripping. Applying a thicker application of paint stripper is also more effective than a thinner application, as this also counteracts evaporation.
Q. I've just stripped back the paint on timber, but there are still stains. Why?
A. Paint strippers are effective in removing coatings. Most stains actually penetrate the timber and do not form any coating and as such, cannot be softened and penetrated by paint strippers.
