I was recently asked to review Sadolin Superdec for Decorators’ Forum UK. I’m a self-employed decorator with 14 years of experience so you won’t be surprised to hear I’ve used Superdec many times before, but sometimes it helps you to actually sit down and write a proper review to help you crystallize your own opinion about it what you think about a product, its good and bad, and so on. I hope you find my review helpful.

For those who don’t know, Sadolin Superdec is a water-based topcoat for wood outdoors. It comes in a semi-gloss finish (although you can also get high-gloss black and white), with a wide range of different colors (some bespoke Sadolin shades as well as a selection of BS and RAL colors) and is very flexible and flexible when it dries means it is much less prone to cracking and flaking, so it should last a long time; The can says “10 years of protection”. It is self-priming and underlining, which means that in many situations you can get started right away when you have completed your preparation. In the case of very resinous woods, however, you should probably seal them with a suitable primer beforehand. Because it’s opaque, it’s the ideal product if you want to make a significant change in color, and Sadolin says it works for any outdoor woodwork except decking. You can shop in 5L, 2.5L, 1L and sample cans; I usually get mine from my local Crown Decorating Center, but I know Brewers has them in stock too.

I’ll start by saying that I’ve used Superdec many times and I’m a bit of a fan, although there are a thing or two that I don’t like; no problems per se, more things to consider. But my overall feeling about this product is very positive. Sadolin recommends applying with a synthetic brush; The can also says you can spray or use a roller, but the website says brush is best, and I usually do that.

I recently had to paint a small shed for one of my older customers and he happily took up my recommendation on which product to use. When choosing the color, we encountered the first of my minor problems with Superdec. They have a huge variety of colors available (around 300 if my math is correct) but in my experience they never match the color chart! They ALWAYS turn out a shade or two lighter than you expect and don’t even try to get a really dark color because I don’t think you can! So it took four sample pots to find the color my customer was looking for; At around £ 5 each, does that make a dent in the budget that could certainly be avoided with a more accurate color chart? Anyway, we finally found our color (the somewhat unimaginative “Light Green”, but then again, it’s nice to know what to get instead of guessing what color “Armadillo Gizzard” will be!) So I trotted off to my local CDC for a can.

Here’s the next issue – how big do you need a can? This is not only Sadolin’s fault. The can and its website say 1L will cover “up to 10m2”, although the Brewers website says up to 15. If you read the fine print, it is based on smoothly planed wood; Mr. R.’s shed was certainly not smooth! So I bought a 2.5 liter can and almost everything went straight to the top. Bought a second can and more than half of it is left after the second coat! In my experience, on wood that hasn’t been painted, the wood really soaks up the first coat, so you get through more than you might expect. Less of a problem with the second coat. It’s also fair to say that the wood in question was quite rough on this job, so the surface area is actually much larger than that of smooth wood. Finally, I tend to apply a really thick, thorough first coat and more of a “normal” second coat. Sadolin says that it takes up to three coats of paint on untreated wood, but I’ve always found two is fine as long as you are really thorough with your first coat. So the estimate of how much you need is my second little gripe, but I’m not sure how to work around this when you are faced with so many different surfaces to paint on. Experience, I think….

Anyway, I’ve been to Crown, I’ve got my Superdec and I’m ready to rock. The sun is shining and Mr. R. really wants his shed to be renovated! And as you can see in the photo (right), because the opacity is so great on this product, it didn’t take long before he could see the transformation beginning. As I said, I like to have a really “thorough” first coat; Apply lots of paint and work it into any small problem areas in the wood grain to make sure everything is really well covered with the first coat. Superdec is really easy to work with, I think it’s a nice consistency; thick enough that it won’t run and drip all over the place, but thin enough to work with. It was 23 ° with a light breeze when I started, perfect dry weather! Sadolin says it will be touch dry in 1-2 hours, but due to the absorbency of the wood and weather conditions, it was touch dry in less than an hour. If you work outside in the sun all day, it will dry on your brush, so make sure you either have spare brushes or the option to rinse your brushes out after a few hours. But the first coat went like a dream, great opacity, and although you could still see the texture of the wood grain, the original wood color was completely erased after one coat.
