applying the g4

hi all,
  sorry a bit late again,but here i am,we recently discussed the render finish on the
pond,and i said make sure it was dry before painting with g4,remember the warmer
and windier the weather the quicker it will dry,
  assuming we have now cleared the pond of all dust and debris we can now paint the
pond,we prefer to give the pond 2 coats of clear followed by 2 coats of colour we have
tried blue green and black,but we always recommend black,as this always looks nice and
does not suffer from the stains you get from algae,however the choice is up to you,
     when applying the clear coat,you will find it is quite thin and is easy to apply with a
brush or roller,the roller being the fastest,once you start painting,start at one end of the
pond and start from the corner working your way around the outside edges then the floor
working into the corner,depending on the weather the g4 will become tacky once tacky
you start with the second coat,making sure you cover all section carefully,then put the
colour coat on,again some people find one coat is enough when applied generously so
again it is a personal preference but we prefer the 2 coats of colour,
please note when walking on the g4 it is very sticky but causes no problems with the final
finish,but you may find you need to put the brush or roller onto a shaft to allow you to reach
 into the pond in the corner where you get out as this is the most difficult to reach once you
get out of the pond,
  why do we need to apply second and third and fourth coats while the g4 is still tacky well
the reason for this is if the g4 is allowed to dry it forms a glossy topcoat finish,this makes it very difficult to get good adhesion when painting over the top of it,so if the pond is to large to
complete in a single day you would need to sand the top surface with 1200 grade wet and dry
to allow the final coats to stick to the surface,so it is possible to go back to it when you are available
but it just needs a bit of preparation before you can get started,but the results are pleasing and
long lasting giving years of reliable service,
next blog we will go over fibreglass finishes to the pond,until then i hope i have given you food for
thought regards
