Will Semco affect my caulking?

No - Semco will not affect any proper grade marine chalking as the process of Semco application is designed not to interfere with this standard of caulking. We recommend you try a test area first just in case the caulking on the vessel is of inferior quality as this can lead to the cheaper caulking being left sticky. Should this be the case just call us and we can advise further.


How is Semco different from others?

Semco Sealers allows the wood to breathe. Wood expands and contracts naturally throughout all weather conditions, by using Semco it enables the wood to act as it does, Semco does not block or obstruct the surface of the wood because it soaks into the wood and protects from within, avoiding the cracking and splitting that some other products can cause.



When was Semco established?

Semco was first established in 1976. It was and continues to be used by thousands of professional boat builders.  Thankfully it is now available worldwide for everyone to use allowing all of us to be able to gain the professional finish we want.


How long does unused Semco last?

If you have any Semco left over once you have finished your project - just replace the lid tight, gentle turn the tin upside down and back up the right way to create a seal from within and store above 5 degrees and your Semco will be good for top ups whenever you want it.    


Can Semco be used on other woods apart from teak?

Yes Semco can be used on any hard wood and also on pine.


Do you have any tips on applying Semco Sealer?

Yes - Firstly, make sure the wood is DRY prior to sealing! For the best results follow this advise and you will be fine. Trying to cut corners at this stage is really not worth it. If your not sure please call us and we will advise you.

Always use a lint free cloth or foam brush where you can; this will enable you to control where you are putting the sealer, avoiding flicks and splashes.  

When using Semco Sealer for the first time apply two coats - your first coat will be absorbed into the wood and almost disappear, it's the second coat that will give you the colour you've chosen. On future applications you can choose to do one or two coat top-ups for maintenance.

If you are in doubt at any point of the process just call or email us - we are always here to help.
