Attach Luan to Concrete
Attaching Luan to Concrete Floors, is possible if you first overlay the concrete with a think material such as plywood, then use the Laun Material overtop of that. You should use fasteners to attach the thicker plywood pieces to the floor. The best option when using fasteners is to use nails or cememt nails. If you're using the nails made of cement you must first make sure that all the heads of the nails are covered in a putty or smooth finish. The reason for this is that the nail's hard top surface over time will destroy the the laun board material.
Lauan Wood : What is It and Where to Get It?
Lauan Plywood is made up from multiple layers of thin sheets of lauan wood pressed together and glued together with the grain alternating direction. This gives lauan plywood it's great strength Luann usually uses a solid core material which is compressed between two layers of veneer.
The veneer is usually some species of low grade mahogany. Luann is typically used in interior applications such as for the under laying of laminate or vinyl flooring. It's also used to make hollow core for interior doors.
Benefits of Lauan Wood
This alternation of the grain is called cross-graining and has several important benefits: Lauan Mahogany Plywood Vaneers reduce the tendency of wood to split when nailed at the edges, this is a benefit for many do it yourself jobs, especially when you consider that most do it yourself'ers are novices in jobs for the first time.
Another advantage of Lauan Plywood Vaneers is that they reduce expansion and shrinkage, providing improved dimensional stability; and it makes the strength of the panel consistent across both directions.
There is usually an odd number of plies, so that the sheet is balanced—this reduces warping. Because plywood is bonded with grains running against one another and with an odd number of composite parts, it is very hard to bend it perpendicular to the grain direction.
