When I bought my house I was told that I need to repaint the summer house every 2 years. There's a 2.5 litre tin of paint of the specific colour along with another with a little left in it, in the garden shed. I went to the paint shop the previous owner used and that specific paint gas been discontinued, apparently a few months before I bought the house.
The guy said he can make up a colour that's similar but it's a different type of paint, a stain.
I'm not sure if I should go for this or use what I have already (not sure if it would do the entire summer house which is around 3 meters long and there's also a small garden shed needing done).
Any advice would be appreciated. I'm not great at DIY and don't want to mess it up. Thanks
