Clean old silicone / sikaflex

Has anyone got any advice on removing old silicone / sikaflex from a hull? I attempted peeling it, and cutting but its a painful task.

When I first bought the Ballistic I put some rubber matting in my anchor locker to try and stop damage from when the anchor is bouncing about and this was stuck down with silicone as this is all I had

I have since changed my mind as I don't like the idea that damage could happen and I wouldn't know about it - as its all covered up, so I have removed the rubber matting and now I am left with the rubbish stuck to the hull, I want to remove all this and clean it out before putting some removable mats in place and some tubing to hold the anchor..

If it is silicone then you can get a remover from B&Q/Screwfix, if it is sikaflex my only suggestion would be dynamite.

Sikaflex, I use White Spirit to remove it, however it is always an amount of hard work.

I think most is silicone tbh as I don't think I had sika at the time. If I got a remover from B&Q/Screwfix - I take it that this will be a solution/gel - will it damage the hull?

A lot of wiping and rubbing but the liquid in them does seem to loosen it up.
On baths, tiles etc that is

I am just more worried about causing damage to the hull by using strange and wonderful solutions, I think a blade and a lot of manual labour with a little solution will be my only option..

Hi Steve

Yes it is a liquid that you paint on, softens and makes the silicone a bit jelly like. I used it on my deck and transom in a small area with no problems but please do not take that as any form of guarantee.

Good luck

Andy
