Brush Sanding of Mouldings Made Easy


Brush Sanding of Mouldings Made Easy by Jacob MalherbeSanding mouldings has always been a long and slow job in the small shop but now a new machine on the market are ready to set a stop to that.The QuickWood moulding sander will do brush sanding on linier mouldings at up to 50 feet per min.
The machine will remove light knife marks and prep the wood for staining and sealing.The prep is very important to the moulding as uniformity in the stain color comes from this prep. The prep is a uniform sanding of the top surface of the whole moulding. The top and the bottom of the moulding will get the same sanding and by doing this the same uniform stain color is achieved. Brush sanding mouldings in this way prepares the moulding not just for the staining but also for the next step, namely the sealer coat.
When the sealer coat is applied to the moulding the pre sanding with the Quickwood moulding sander has made sure that no sharp edges are on the moulding. This does not mean that the brush sanding distorts the profile it only means that knife sharp edges are slightly broken. The rules are that a sharp edge will not be able to absorb very much stain or sealer and thereby be very weak and a possible point where the homeowner would breach the sealer coats and expose raw wood. To make the edges as strong as possible a light break is perform in the raw wood sanding so the stain and sealer coats sits better on the edges.After stain and sealer has be applied and the moulding has dried the Quickwood brush sander is now ready to do sealer sanding on the moulding.
The speed of the spindles are reduce for a softer sanding and again speed of up to 50 feet per min can be reached for sealer sanding on the mouldings.The machine can be setup with 150 grit for pre sanding and 220 grit for sealer sanding. Any grit from 80 to 320 is available for the machine. Special sanding applications like Rustic look, Antic look or South West look can also be achieved by using steel brushes or stiff tynex brushes.The moulding sanding machine comes with 2 top heads, made with variable speed to change the aggressiveness of the sanding on the moulding. One sander on the left side and one sander on the right side also with variable speed control. Driven rollers conveys the product though the machine at a variable speed from 10 to 50 feet per min.Pressure rollers are adjustable in height together by a hand wheel crank, minimum length is 14 inch.This machine will take care of bottlenecks in the production of moulding as finish sanding and sealer sanding is now an easy task to do.
