MDF quality from B&Q

[Hysteresis]

I have used B&Q MDF many times over the years.
I recently bought a 8 ft x 4 ft sheet of the stuff and the quality of it was to be blunt - rubbish.
I have routed MDF and used a circular saw on it before and the result was reasonable. This latest junk left the prepared edges almost like a felt finish and hand sanding did not improve the surface.
Does any one know if B&Q has changed their supplier to a much cheaper source and has anyone any idea where I can purchase an improved quality of MDF.
I have tried to source HDF but without success, again anyone any idea of a source of HDF?

If you want a better finish to the cut edge then use MR MDF

One last thing; don’t be ashamed of using sharp tools and sandpaper.

My posting did say I used sandpaper and the prepared edges were still rubbish. Although I didn't say in my posting, the router bit was a New one and an expensive one at that. The probem is poor quality MDF.
Sorry but what is MR MDF ?

Would MR MDF be Moisture Resistant MDF.
If it is where can I get it as I only buy one or two sheets at a time and purchase from Timberworld would be inhibitive due to transportation costs.

I must say though my B&Q beat all the prices of my local timber yard when it comes to sheet materials, and convenient with 5 free cuts. Their planed timber is pretty competitive too however there treated timber is not the cheapest. The last sheet of mdf I bought was pretty good quality.

Yes MR is Moisture Resistant.

If Timber world is your local suppler then you have no choice but to use them. But you can save on transport if you are the proud owner of a battery powered circular saw. With a stick of millimetres, a chalk line or strait edge and your trusty battery powered circular saw you will surprised what you can achieve on site.

You may be using a light grade MDF and as in most light weight material the core is less compressed (more open texture).

If you sharpen your hand plane you can achieve very, very acceptable results by planning the edge of MDF.

Thanks a Milliom awbcm,
I am now so much wiser about MDF. I do have table saws etc ets but my problem is not the cutting but the transportation of 8 x 4 sheets of material, they do not fit readily into an XK Jaguar.
Your information is fantastic and and I thank you so much for your time and expertise.

That’s why you take a battery powered circular saw etc to the timber yard and roughly cut the 2440 x 1220 sheets to size. It’s the same as getting B&Q to do the rough cutting Yes?
