Polytrol works by saturating deep into the surface of the door, not by leaving a coating, so removal of the excess Polytrol is important. Polytrol usually can last for 24 months+ before re-application is necessary. It depends on the sunlight, rain and pollution in which it is subjected to (i.e living near to the sea may mean an earlier re-application of Polytrol is necessary as it is subjected to a harsher environment). However, if you’d like to modernise your home’s energy efficiency, you may feel like there is no other option but to change the doors. As you have suspected, using a wire brush will indeed leave scratch marks and Polytrol will not cover these. In fact they will probably accentuate them.

French doors have such an iconic style. And while there are modern uPVC replacements, nothing is going to do your home’s style more justice than the original doors.Any rot we find on the door and the door frame is then repaired. For larger areas of damage, we splice in fresh wood. One of the bigger benefits of restoring period doors rather than replacing them is that it keeps bespoke doors in place. Door restoration is often much cheaper than replacing the door. It is also the best way to preserve the look of your home too. By changing the doors to modern uPVC French doors, you can drastically change the looks of your entire home. Both of these products are available in a 100ml sample pot – we would recommend purchasing these and testing them out in a small area first. Then, as long as the original colour is not too faded, you could use Polytrol to restore the colour: https://www.owatroldirect.co.uk/product/polytrol/

These are heritage doors that add so much character to your property. Removing original doors takes away a lot of the charm and style of your home. Once you have finished using Polytrol, clean any brushes or other tools you may have used with white spirit. Cloths can be left flat to airdry before discarding.

Although we didn’t have any mildew on the door, if you do, don’t worry. Mildew can be treated with a 50:50 bleach and water solution. Just scrub it on, leave it for 10-15 minutes, then rinse it off. Polytrol will restore the colour of the over coated paint, but unfortunately will not hide any brush marks, patchiness or any other blemishes present. Before application, you would need to clean the surface thoroughly with warm soapy water or Net-Trol ( https://www.owatroldirect.co.uk/product/net-trol/).
