Question : Is it good to put luon down
Answer : It is always best to refer to the material manufacturer's installation guidelines/specifications for how to best fasten. In this instance that is the maker of your luon. If you are referring to Luan Plywood, our answer is no. Although this tacker will drive a staple into that product with no issues, the staple is not nearly hefty enough to hold that plywood to whatever wooden substrate is below it. These stapler is best used for attaching thin sheeting to plywood, such as felt paper to roof sheeting, builders paper to plywood or even homewrap or polyethylene plastic sheeting.
