revive a composite front door with Polytrol

How to revive a composite front door

We always love to hear about our customers’ restoration projects but when we get word that a customer wants to tell us about their experiences with Polytrol, we can’t help but feel a fizz of excitement for one of our favourite products.

With over sixty 5* customer reviews, we’re not the only ones who think that Polytrol is amazing. A deep penetrating oil, Polytrol not only restores colour on a wide range of surfaces but also protects against blemishes and corrosion.

Paul at Dunne & Sorted got in touch when he was looking for a product to revive a customer’s faded composite door and we recommended Polytrol. He’s sent us some photos of the project before and after he’d completed it and some instructions on how he did it. For more information about Paul and his company please see his bio below. We couldn’t wait to see the photos and share them with our other customers. I’m sure you’ll agree that the transformation is nothing short of marvellous!

How did Paul do it?

revive a composite front door with Polytrol

1. Prepare the surface

Firstly, we had to prepare the door.

We did this by removing any dirt, grease, grime or mildew from it. If there had been any wax or polishes on the door, we would also have needed to remove this but there were not.

We cleaned the door with warm, soapy water then rinsed thoroughly.

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.

After cleaning, we then left the door to dry for 24 hours before applying Polytrol. Make sure that your door is completely dry before moving on to the next step!

2. Apply the Polytrol

We then liberally applied Polytrol with a brush (you could also use a cloth) and then left it to work for 10-20 minutes. Before it started to become tacky, we then wiped off any excess with a clean, lint-free cloth.

Then we left it to dry.

The door didn’t take us longer than 20 minutes so we could do it all in one go but if it will take you any longer than 20 minutes, you will need to work within areas that can be completed within this time-frame.

To achieve the shiny finish, we then buffed the surface with a lint-free polishing cloth.

3. Clean up

After finishing, we cleaned the brush with white spirits.

This satisfied customer used Polytrol to revive their composite front door but it is also great for a wide range of other uses, including brightening faded car bumpers and reviving the gelcoat on your boat!

Polytrol now also comes in a handy 250ml spray can – great for quick application or for difficult to reach areas.

  1. Advice requested: I’m feeling a bit gloomy as I’ve made a silly mistake in trying to clean some spots of alien paint from the inside of my front door. Some little bits were stubborn so I removed them with white spirit. An hour later, I realise the door now looks patchy where I did this. The surface of the door feels different as well – it is clear that I’ve managed to remove the surface by with the white spirit. Is there a way to recover the situation? I believe the front door is a composite one, and it has a dark brown wood finish.

    Many thanks, Lewis

    1. Hi Lewis,

      You could try a sample pot of Polytrol to see if it will recover the surface of the door. We’d recommend trying it first in a small area to see if it will recover the surface.

  2. We have used Polytrol on our brown composite front door, which had faded in patches, caused by the sun, rain and dirt from passing traffic, it now looks like it did when we had it fitted. The company were prepared to fit a new one under warranty, but we realised that it would probably just happen again and we are really happy with it, especially now thanks to Polytrol.

  3. Hi

    I have used this product on my black composite door, but i still have faded patches within the grain. Can I do it again or will that make no difference now?

    1. Hi,

      Thank you for your query regarding the use of Polytrol.

      Your problem could be the result of a few things;

      1) The surface wasn’t completely clean prior to application (For the best possible result using Polytrol, the surface must be clean, dry and free of dirt, grease, grime and mildew. All waxes, polishes, silicone etc should be completely and thoroughly removed).
      2) The Polytrol may not have been left to work for long enough before being wiped off.
      3) If the surface has absorbed the Polytrol unevenly it can create matte and shiny patches. If this happens, you should then move surplus oil from the shiny areas to the matte areas, remembering to wipe off excess Polytrol with a clean lint free cloth before it becomes tacky.

      I hope this is of some help to you.
      If you still have any queries regarding the use of Polytrol, please call us on 01582 592707 and we will gladly assist you.

    1. Hi Mark,

      Thank you for your query.
      Unfortunately the way to remove flaking from composite doors is by sanding – However you must be careful as sometimes coatings on composite doors are what prevents moisture ingress.

      If you have any further questions, please don’t hesitate to ask.

  4. Hello

    Regarding the above query “I have used this product on my black composite door, but I still have faded patches within the grain. Can I do it again or will that make no difference now?”

    I have the same issue but you have only stated why this may have happened, so my question also is;

    Can I apply a second coating over the now very dry first coat?

    Best Regards

    Paul

    1. Hi Paul,

      Thank you for your query.

      If the first application of Polytrol was not successful and the surface has remained dry and discoloured, then you can re-apply a further coating of Polytrol.
      Just remember that the surface must be clean, dry and free of dirt, grease, grime and mildew.
      All waxes, polishes, silicone etc should be completely and thoroughly removed as this will hinder the penetration of Polytrol.

      I hope this was helpful, please feel free to contact us at sales@owatroluk.com or 01582 585266 if you require any further assistance.

  5. Hi. I have a navy blue composite door but there have been red dots appearing all over it. I have tried cleaning it but they do not come off. The people that fitted the door have no idea what may have caused it. Would your product help in this case?

    1. Hi Jo,

      This is a hard one to answer as we have never heard of this happening before.
      If you wanted to try and see if Polytrol would work, we suggest purchasing a 100ml sample pot and giving it a go. You can find the product page here: http://www.owatroldirect.co.uk/product/polytrol/
      Failing that, we can only recommend you speak with the people who fitted the door again and ask them to look into it further as there may be a manufacturing problem.

      I hope this answer was helpful and I hope this gets resolved for you.
      If you have any further queries please do not hesitate to ask.

      All the best,
      The Owatrol Team
