Just wondering if anyone has any knowledge about wood treatment for the composite boards sold here in Thailand.

 

a) Are particle boards / Chipboard /Wayrock / Plywood pre treated here before selling - ( I have my doubts as I was in Global House on Saturday and some of their wood door frames were like a colander with wood worm.)

 

What would be the best "Brush or Spray" on anti termite treatment? 

C: Can it be applied from one side of the wood and then soak in or do you need to cover both sides?

 

I was thinking of using Steadfast / Chaindrite and just giving the wood a good soak, but I don't want to mess up the glue so it expands like a sponge.

 

Any suggestions?

I wouldn't use particle board here (regardless of whether it is sold as "treated"). Also, I suspect that using Chaindrite or similar products would cause the boards to swell and disintigrate.

 

Plywood can be treated effectively with Chaindrite (generously applied by spray or brush to both sides (and the edges) - Marine quality plywood can be found, but I have been warned that some of it is not the genuine article (despite the very high price).

 

There is a product named Viva Board, which is a particle board made with cement and wood chippings. Comes in various thicknesses, nice smooth surfaces, and is impervious to termites. Also, will be OK in most outdoor conditions. I have bought it at HomeMart (Siam Cement Co.) and seen it at most of the usual DIY places.

Thanks, I will look up that Viva board. Guess a good quality ply is the way to go. I want to make a workbench, all of the legs and sides are heavy duty 4 x 6" Mai Deng, but I need a nice flat surface for mounting a router, mitre saw and an inverted circular saw, I saw some decent looking 3/4" MDF, I was thinking of gluing to sheets together and then giving them a dose of chaindrite or even that chaindrite powder. Does MDF swell like chipboard?

 

Thanks for the reply!

I have made table tops using the "real" wood boards that are assembled from lots of small planks, looks a bit like a parquet floor. Not particularly cheap but actually looks pretty good when sanded and stained (Chaindrite).

 

My workbench top is 15mm "high quality" (sure it is) ply, again generously coated with Chaindrite. The workbench frame is steel (left over from building the chicken-palace).

Stay away from MDF, unpainted or unsealed It is even more susceptible to moisture than chipboard. If will swell at the edges if you soak it with chaindrite.

I'd suggest a couple of sheets of 3/4 ply laminated together. Easy enough to frame the edges with a solid wood batton to make it more robust.
