HEAVY DUTY STRIPPING DISC

This is a flexible single sided stripping disc (NEW). It is our primary stripping disc and its effectiveness depends entirely on what sort of paint and how many layers are to be stripped. The Light Duty stripping disc is better for softer timbers such as cedar or pine.

Because of the score marks left by the Heavy Duty Stripping discs (HDSD) and to a lesser extent, the Light Duty Stripping discs, there is a need to follow up with an A & FD60 or a A & FD80 grit finishing disc. We recommend that you use the HDSD until the timber just starts to show through and continue until you have completed the section you want to strip. The result looks a bit ugly but you haven’t unnecessarily removed much timber. You then need to switch to the LDSD to remove the remaining paint. This disc leaves fewer score marks which can more easily be removed with a finishing disc. These discs last discs will do the final surface preparation leaving the boards almost like new and ready for painting. In some cases the 60 grit disc will strip acrylic painted surfaces back to sound paint without the need for stripping. Just try them to see how they work in each different situation. It is false economy to use the HDSD disc then wait for the timber to dry before dry sanding with an orbital. Just get straight in with the 60# or 80#, hose down and the timber is virtually ready for painting. When the timber has dried you will easily see any bits you have missed with the Finishing disc and these can easily be touched up with your dry sander. Most of the hard work is done by the HDSD so it is a lot quicker to use our recommended three disc process. For example you will probably spend around 15 minutes covering 5-8 sq meter with the HDSD. The removal of the remaining paint with the LDS will take about 5 minutes per sq meter and the FD80 will take about 1 minute per square meter. So the ratio of discs is about 10 HDSD, 5 LHSD and 1 FD80.

There is no need to use chemical strippers with this disc.

The disc will yield on average 5-8 sq meters in around 15 minutes per square meter for most painted surfaces except hard lead and hard lead based enamels where it may only yield 1-2 sq m. When using the disc for the really hard lead paint, the disc will rapidly loose its edge after 1-2 meters, so taking labour costs into account, it is more cost effective to stop after 2 sq m and change to a new disc. In that way, the disc cost works out at about $8 which is still way cheaper than applying stripper at a minimum of $25, before application and removal.

COST SUMMARY:

• $3 -$8 per square meter
• 15 minutes per square meter
