The Alderson® sanding machine has been designed to be used in conjunction with water.  It is the water that significantly reduces the frictional heat build-up that damages the paint substrate which is often invisible after sanding – especially when sanding water based painted surfaces.  The damage results in blisters forming under the substrate paint and these blisters often don’t become obvious until the surface has been repainted.  The use of water virtually eliminates clogging.  Clogged paper also contributes to heat build-up. 

 

So this machine extends the life of its abrasive paper and significantly reduces the time it takes to prepare a surface for painting.  The machine can also be used in wet conditions and it also eliminates the need for pre-sanding preparation such as water blasting and wiping the surface dry before dry sanding.

​

Features Summary

​

• Water prevents heat build-up causing substrate damage.

• Water reduces clogging.

• Water means no dust to interfere with washing on the line or cars parked nearby.

• Water means you don’t need to water blast first.

• Water means that the abrasive discs last much longer – 2 discs per side for an average sized house.

• Water and no electrical leads means surface preparation can be done on a rainy day.

• Water with the Alderson sander means that the slurry from lead based paints can easily be collected in the Alderson “Enviromat”.

• No dust masks or vacuums required.

• There is no need for power cables so trades people don’t need access to the property.

• No need for dust masks or vacuum bags.

• No expensive backing plates to replace.

• Used in conjunction with our “Enviromat” it is the safest system for the removal of lead based painted surfaces.  There is no lead based dust and the sanded lead particles are safely collected in the Enviromat with the water passing through the mat.  For this reason it is now the NZ Master Painters preferred system for the removal of lead based paint.

Cost Comparisons

​

• Generally speaking the Alderson sander is at least 6 to 8 times more productive than any over system.
  The use of the water and the speed of the machine means that the sanding discs last a very long time.

• For example an acrylic single sided disc (SSC150 – 60#) will sand between 20 and 30 square meters which means the abrasive cost for that disc is between 65 cents and 95 cents per square meter (6 and 10 cents per lineal meter).  However the real saving is in time.  It takes just 6 seconds to sand a lineal meter compared with an average of 36 seconds for a dry sander.

• With the 16# stripping disc (TSC150 -16#) it will strip between 10 and 20 square meters of paint up to 12 or so layers thick.  It needs to be followed up with a finishing disc, such as the 60# finishing disc (TSC150 -60#) to remove the score marks. Using the cost of these two discs the cost is between $6.00 and $12.00 per square meter or $0.60 and $1.20 per lineal meter.  To achieve these costs you will need to apply one coat of Sea to Sky stripper SPC 203 (blue in colour) as this softens all the layers of paint and accordingly extends the life of the stripping discs by a factor of three or four times.  That is, without the stripper, the coverage may only be 2 -3 square meters.  Note that all surfaces are different and these cost figures are indicative only but fairly represent achievable results providing the machine is used correctly.  Again the real saving is in time.  The 16# shredder will remove the paint at a rate of 1 square meter every 6 to 10 minutes.  No other method comes close to this.
