2 part or 2 pack fillers
Are so called because they conta8n a base filler material and a seperate chemical setting compound; these '2 parts' are mixed together, generally in proportions of 1 golf ball size of base filler material to 1 pea sized portion of the chemical setting compound.
Thet set very quickly, and very hard (dense)!
Historic Building Restoration
Historic Building Restoration involves using materials which support the very important transfer of moisture; two-part /two-pack fillers certainly do not do that!
caution!
Mark Eting has been known to tell lies!
Timber Rot Repair
The use of two-part (AKA 2 PACK) fillers on Historic buildings has increased immensely because these fillers 'set' quickly and can be abraded to a very smooth q2.
The image above clearly states: "Repairs Wood Permanently" - yet another example of Mark Etings work.
We know very different!
We do rarely use them; but only on what we know to be appropriate substrates for them (timber is certainly not included) and we advise caution to everyone because they are extremely dense fillers once set which can simply trap and hold moisture when used on the wrong substrates; for example: when used on timber substrates they help to speed up the processes of timber rot by trapping moisture deep into the grain, which also further encourages fungal/mould growths and beetles to move in and lay their eggs.
A WORD OF WARNING!
Once people start to see the chemical setting speeds of these fillers in this world of 'I want it now!!!' It's very easy to get carried away and start slowly killing your home with these fillers; A lot of today's commercial painters, trading under the guise of 'Decorators' also like to use them because it's money in the bank faster for them.
Imperfections/cracks/splits in timber can easily be filled with traditional linseed oil based glazing putty which allows natural moisture transfer, especially when correctly overpainted with a linseed oil based paint system.
Vehicle body repairs
Whilst Mark Eting promotes these fillers for use on buildings these days, it wasn't very long ago when you could only buy them from vehicle body repair suppliers, because that's where they originated and Mark Eting only focussed on that industry, where they are still used today, until he spotted a potential 'sales expansion opportunity' of course, but very few cars or vans are made from bricks, mortar, plaster and timber!
