Well had a break of a few weeks, now back on the job.
So now have a Red Oxide boat rather than Yellow one………………
Although these next stages are a bit ‘ samey’, I have learnt a few things as it happens.
For example, I had put three coats
of the Halfords filler
on a couple of days before I had a break. Now when I left it all looked dry, well cover
ed and ‘solid’. When I came back to it some weeks later the longer drying period had shown up some gaps.
Well not gaps actually but ‘mouths’ where tissue I had overlapped had pulled apart slightly. interesting, easily fixed with some 240 grit sanding
, showing that the drying period is longer than it would appear. At least for filler
which is a much thicker substance than just spray paint
With the sanding
, I had not appreciated the difference between the grades say from 240 upwards (or is it downwards) as my experience was with doorframes
and floorboards. For the stage I am at, 240 and 400 seem very effective and leave a good surface. What I did find was how important dust becomes………………
The sandpaper rides on it (the powdery dust) and so becomes much less effective and I found brush
ing with a thin 2 inch brush
worked well, using the vacuum cleaner to clear up later. I did try blowing it off with the heat gun
but that put the dust up in the air too much. it is my intention to try ‘wet and dry’ approach for later coats
and looking for a better answer when it comes to finishing coats
Another interesting discover
y was cover
age per rattle can.
It may be my ‘beginner’ technique, but it seems to take a lot of paint
On this size of boat hull, 44inches (112cm) by 14 inches (36 cm), it took a 500ml rattle can of yellow filler
for three coats
. For two coats
of the red primer
it took the whole of a 300ml can.
ed, using these ‘rattle cans’ for the first time, that the primer
on its own comes out differently to the filler primer
. This unsettled me for a minute or so but appreciate may be due to the different density so will be aware next time.
Another issue that became obvious was…………..I must improve my ‘masking off’ !
So that is it so far. Next stage is - going to buy a couple more cans for the finishing coats
, do a bath test, mark the white line point, more sanding
down and then start applying the finishing coats
Any helpful comments will be much appreciated.
