Perfect sanding is a must for a clean and attractive surface finish. Imperfect, loose coating must be completely removed. Intact coating should be completely sanded. We recommend a medium grit (100 to 150 grit) sandpaper which makes a good starting point for most projects, from sanding unfinished wood to removing old varnish. Finer grit (180 - 240 grit) sandpaper is great for removing the scratches left by coarser grits on unfinished wood and for lightly sanding between coats of paint. We have a range of handy D.I.Y. friendly packs exclusive to Allfinishes of abrasives at great prices from industry leading abrasive manufacturer Klingspor to help you with your project.

If you are sanding by hand we recommend using Klingspor PL 31 B Sandpaper Roll or Klingspor PL 31 B Sandpaper Sheets. If you are sanding using an orbital sander Klingspor PS 22 K Velcro Discs, a delta sander Klingspor PS 22 K Triangle 96mm, a belt sander Klingspor LS 309 XH Sanding Belts or a hand held sander Klingspor PL 31 B Sandpaper Strips.

The wood moisture content for the application of impra coating systems should be between 12–15%.

If you are prepping exterior surfaces before painting, we recommend Tesa 4440 Precision Outdoor Masking Tape which is suitable for almost all outdoor paint works and all common kinds of paints, stains and lacquers.

Stir well before use. Do not dilute. Intermediate rubbing down with a Scotchbrite pad is recommended. Do not use steel wool. We recommend the use of a brush with a combination of synthetic and natural bristles.


Always consult the technical data sheet before use. Before use, read the technical data and product information. Even when working with low emission products one should take care of the customary protection measures.

impra Profilan Secur can be applied by Brushing, Flow Coating or Spraying. We recommend the use of a brush with a combination of synthetic and natural bristles such as the Purdy Monarch Elite or if you require a brush with a larger pickup the Purdy Pro-Extra Monarch. Applying the product too generously and with insufficient ventilation will lead to delays in drying.

With untreated wood used out of doors and exposed to insect and fungal attack we recommend a pre-treatment with a biocidal primer such as impa Profilan Prevent.

Allow to dry for approximately 6–8 hours with good ventilation in between coats. Lower temperatures and/or higher air humidity can increase the drying time.

Please note Oily and Exotic timbers are proven difficult to treat with water based products. Use white spirit based primer on this type of timber.


You can overcoat with products of the impra Profilan range such as impra Profilan Opac as well as with normally available commercial waterborne paints. If you are using other paints we advise a trial coat as mixing paint brands may invalidate the integrity of the system.
