"This is the second time I have used this product. I am building an 8' x 8' shed from scratch and as I cut each piece of timber I treat with Sika wood preserver., especially the cut ends. It doesn't smell too strong and absorbs very well. Although it absorbs well into wood it is kind on the hands,doesn't burn,stain or irriitate.As it is clear it still leaves a nice finish (which can be stained if required) one tin will do the whole shed as I am using planed timber. I would give 5 stars but it is a little pricey, would definitely use again though as have not found anything better."
