It’s difficult to answer this without some specific information. We recommend talking to the experts at The GoodWoodGuys.

My house has a surface coating (paint, stain, etc.) - how do I remove it?
It is best to get a professional to do this for you - this can be a complex process, using specialised equipment and chemicals. The results can be dramatic, as warped and cupped timbers can be returned to their near original profile, and the original natural colour and beauty of the wood restored.

I want my timber to age and weather naturally
Sure, but to get the best life out of it, we recommend using CD50 to protect your timber. It can still silver naturally, but won’t crack or split, giving you longer lasting timber.

I want my timber to age and silver naturally but want an even silver look all over 
No problem - see our About CD50 page

Do I have to measure the thickness of CD50 after applying it? 
No! CD50 soaks into the timber - it is not a surface film forming product however brush or wipe off any excess after application to stop dripping.

Do I have to put a coat of preservative on first, then several coats of colour?
No - CD50 contains the active ingredients in one mix. If you want a Colourtone, you add this to the mix. It all goes on together. Then you apply the second coat (the same mix) after at least four weeks.

I understand that if I use new timber, the retained moisture must be less than 17% - what is retained moisture and how will I know the level?
Retained moisture is the natural sap left in the wood. This must be reduced to below 17% before applying CD50. Your timber merchant can test the timber and tell you how much moisture the timber contains.

Do I have to wait 4 weeks? - I don't want to rehire the scaffolding later
You can apply the second coat before 4 weeks if it has penetrated in fairly well (e.g. if the weather is dry) - but we recommend letting the first coat soak in well before the second coat, as the longer the time between coats, the better the colour retention will be. In humid or cold conditions it is better to wait until after 4 weeks.
