Hello,

I have a lot of grooved decking boards that someone asked me to redo for them. I need to sand, prime and top coat.

I was thinking of trying to use an electric powered sanding tool to do the sanding, but I am not sure what tool will be able to to sand in-between the grooves?

I was also wondering what would be the most durable long lasting finish to use on the decking? (I am considering spray painting it to save time and also I have decking, gazebos and other outdoor wood that needs doing at the same time so if the weathers right I could maybe get it done a lot quicker if I spray it)

Thanks, looks like a good tool to have and would be just the thing I need for thous grooves
 
Exactly what sort of primer and top coat are you intending to use (and why) as most decking has been treated, and may not take a primer very well. And if you're using a top coat, you'll need an undercoat as well, and that's making for a lot of hard work.

I think the bosch may be overkill, and a normal orbotal sander with 60 grit wuld suffice, as to the grooves, and depending on their width, it may be as simle as sandpaper wrapped around a thin bit of wood, or simply a piece folded over.

These are what I need to do, I am not sure if the decking on the gazebo is the grooved one, I'm quite sure there was some grooved decking on at least one part of the house that I need to do. I want to get it done to a high standard and I hate hand sanding so want to get a tool to do the hard work for me.

I haven't selected the materials yet, I was considering dulux wood stain or maybe a Sickens product that could be sprayed. My main prioity though is to get the best longest lasting finish. So any help on finding the best product would be great.

-I originally quoted the work based on:

  1. Fungicidal treatment (where required)
  2. Sand
  3. Wash down
  4. Prime (where required)
  5. Apply paint/wood stain with two coats.
 
You won't prime on wood stains. Priming is for sealing the wood prior to undercoat and topcoat, but stains work differently, and yes, they can be happily sprayed on as they are quite thin.

Sorry, I meant "Dulux Trade Aquatech Preservative Basecoat Plus (BP)" -I was calling it primer... Would you still use that before applying Dulux woodstain?

What is the best product to use for the decking areas? I want to get the longest lasting finish
 
I haven't used the aqatech yet, but it seems to be for new and bare wood, but yours will have been treated already, so shouldn't need it. A quick look on the woodstain insctructions implys it should be reinfocing the intial wood treatment, but most wood stains are water based, and yours is solvent based, so no, it may not spray. See if you can check with dulux tech support.

I've not done it yet but to sand down deck boards I would try a block of pumice stone. After a few runs it will wear down to fit into the grooves. Ebay do them.

When you said grooved, I thought the planks were

A normal belt or orbital sander would do it, with possibly a bit of carefully made 2x1 cut to size to fit the gaps and covered in sandpaper
