the holiday is over

hi folks,
        sorry for the delay in my posts,but we did a cheeky thing,
we sloped off for a holiday,i said years ago i would not go back
to Spain again so this time we went to Majorca [lol] and it has made
me realise why i said i would not go back again,i mean £1.50 for a
blumming kit kat,and the airport i had to get an urgent over draft
from my bank manager for the 5 sandwiches 2 bottles of coke
1 kit kat and a twix ,it was lucky i did not go with the wife or i would
have been claiming off my medical insurance after hitting the floor,WHY
48 blumming euros,i can buy the whole of Spain for 100 euros and if i
batter well enough can probably get a kit kat throne in as well,
  i have to admit most of us did get something for nothing while we where
there, Spanish tummy sorry to those lovely Thomas cook air stewards who
despite watching my 7 month old grand daughter do her version of the
exorcist acted in a very professional manner and never once passing comment
on the strange colour scheme that suddenly appeared on my jumper and then
t shirt,  its strange when your daughter goes a funny colour and passes her child
back the moment there is a nappy to change,and has the cheek to say that i am
more used to bad smells as i deal with filter clean outs every day,hang on i thought
i was on holiday,well it must be over so time to get back to work,will restart our
blogs tomorrow,until then
regards Paul

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

preparing the pond and rendering ready for g4

hello all,
             today we will go through the render and g4 finish on a pond,the principal
difference with g4 over a liner is that the finish is not flexible so the finish is only
suitable for brick and concrete constructed ponds,
when preparing the pond for rendering it is considered better to remove tight angles
from the pond,the most obvious method here is to angle a block or brick in the
construction stage,so as not to have 90degree angles in the corners[bottom and sides]
this is so we do not have dead spots in the corners,or sharp angles that will be hard
to render and paint,
    if you can afford it it is nice to get somebody in to actually do the render but you can
do just as good a job yourself if you take your time,once again the more time spent the
better the finish,when you are preparing the surface for rendering you must look at the
finish,if you have used concrete blocks then the surface will be rough so you can lay
straight onto this with the render mix,and you will get a good adhesion,but if you have
used smooth bricks then you are better using a pva glue on the surface so the render
will stick,
   when mixing the sand and cement we add chopped Fibreglass strands into the mix this
prevents cracking due to slight movement as the mix dries,we also add a plasticiser as
this allows the mix to become more slippery making it easier to work with,the secret
here is to start with smaller mixes until you become more confident so avoiding waste
and the urge to rush,when applying the render onto the wall try to keep an even pressure
to the float as you push the mix onto the wall,at this stage do not try to smooth it to much
but apply more to the next part of the wall until you have a reasonable area covered at
this point go back to the beginning and start to smooth the render if it is still to wet give
it a little time to cure,if it is a little dry then spray a little water on to it as this will make
it more fluid,keep moving along the wall until you have achieved a good finish,i prefer
to use a wet sponge for the final polishing because you can put as much or as little water
onto it as required,and i find easier than finishing with a float,once you are satisfied with
the finish leave to dry,the drying time depends on the weather but we usually find three or
four days in the summer is fine,once dried you will need to check for any rough edges,if
there are we cheat a little bit and use a rough sand paper to rid the pond of the edges,we
then need to use a blow lamp to remove any strands of fibreglass that may be sticking out
of the render,as if painted will become razor blades on the side of the pond,after this brush
and vac the pond removing any dust or debris from the bottom,and you are ready for the g4
finish,we will cover this tomorrow,and once again we will discuss preparing pipes and
bottom drains at a later date,

installing a box welded liner

hi all,
       today we will discuss the installation of a box welded liner,
box welded liners are more suited to regular shapes but that is not to
say that you have to be square with them,oval or curved ponds can be
constructed by making a template of the top shape,we do this by using
a cheap tarpaulin sheet from a hardware store and cut it to the exact
shape of the pond,this is then used by the manufacturer to produce the
liner,remember to request an overlap,not all suppliers supply a standard
overlap,so always ask,
right we have taken receipt of the liner,we first must open it out and make
sure it is not inside out,you can usually tell because any writing on the
liner is on the underside of the pond so you will not see it when the liner
is installed,
   we then place the liner in the pond taking care to make sure the edge and
corners are properly aligned it is at this point you put some wait on the top
edge of the pond and you can start to fill the liner,as the water enters the pond
start to push out any creases in the bottom of the liner taking care not to pull
the weights holding down the liner into the pond as there is a risk of damage
to the liner,once again the more effort you put into this the better it will look
the advantage with this type of liner you will not have any folds but you may
have small creases in the finished pond but they will be almost invisible in
the finished pond when full of water,as the pond fills keep pulling the edges of
the liner so as to keep the liner slightly stretched so to avoid creases in the
finished article,when full you can install your preferred topping and the pond is
complete just ready to install the filter system which we will cover shortly

fitting the liner

hello all,
            we have now purchased our liner,in this instance we will assume it
is a pvc flat sheet liner,
   we find the liner becomes much more user friendly if we unroll it and lay
it flat on the ground in sunlight, this helps to soften it and make it much easier
to fold when installing in shaped ponds with shelves,
  the thing to note at this point is that all guarantee's state that the liner must be
installed on a suitable underlay,this can be something like a carpet or underlay
that is now surplus to requirements and can make an excellent protector for the
liner[make sure there are no tacks or staples in it] we can also use sand as this
offers a good protector or in some cases the original liner,this assumes the liner
has suffered an accidental damage and offers no risk to the new liner,
  firstly remember the liner is now supple and in its weakest state so when moving
into place make sure it does not snag on any sharp object as it may act as a razor
blade and damage the liner,
  it is better to have two or more people to move it at this time but can be done as
well by one person as long as you are fully aware of where the liner comes into
contact with the ground,
start by moving the liner into a position where the centre of the  liner is in the centre
of the pond,roughly fold the excess liner into the shape of the pond,when you are
happy with this it is time to add water to the pond,remember if you decide to wear
wellies ensure there is nothing sharp in the soles of the boot,
aim to have about six inches of water in the pond as you will need to use this weight
to hold the liner in place,as you are topping up the pond ensure you keep stretching
the liner and start to create the folds we find it is better to create large folds to get
rid of any excess with smaller folds to fine tune,be aware if you slip away for a
quick cup of tea [or pint] turn the water off,it is surprising how much water you can put
in the pond to an extent you may have to pump some water out because the weight
of the water will stop you folding the liner,remember the longer you spend doing this
the better the finish,so as they say patience is a virtue,so don't rush things,tomorrow
we will explain the box welded liner,
  don't worry if you are going gravity fed we will address this when we have finished the
advice on installing the different pond finishes

how to measure a flat sheet liner

hello all,
  as usual i am late with the next post,but here i am so lets move on
i have pointed out the different materials that are common in pond
construction,there are other types but for the time being we will stick
to the better known types,
pvc and butyl liners are by far the most widely
used  because of cost and reliability,when building a pond which has a
uniform style IE square or rectangular and in some cases round, it  is
possible to have a box welded liner made to fit the pond,although more
expensive it has the advantage of being virtually crease free,and can be
installed in a fraction of the time it takes to install a flat sheet liner of
the same size,when measuring for a flat sheet liner it is important to allow
for an overlap as you need to be able to anchor the top of the liner to the
finished top edge of the pond,so if we had a pond 10ftx10ftx4ft deep we
would add 2ft to the length and width this would give us a 1ft overlap on
all 4 sides of the pond,but we also must remember that what goes up must
come down,so we must remember that although the pond is 4ft deep it has
2 sides so we must double the depth so we have a liner 18ftx18ft but what
about our overlap,lets not forget the 2 ft overlap, so we now need a flat sheet
liner of 20ftx20ft this gives us a pond of 10ftx10ftx4ft but it now has a 1ft
overlap on each side,so we can now see where most people can make a
simple error that can leave them with a liner that is to small for the pond,and
as liners purchased off the roll cannot be returned,as the supplier will end up
with a liner he will struggle to sell as it could be a considerable time before
somebody needs a liner of that size,tomorrow we will go through the fitting
process,

choosing a liner for your pond

hi all,
         for some time now we have been asked by customers [how do i choose a pond liner]so i
have decided to turn the next issues of the blog into a help page for the installation of pond liners
in a pond,what i hope to do is separate fact from fiction and give you the logic behind your
choice of pond liner,
  pond liners can be as simple as a pvc  liner, butyl rubber liner,render and g4 or fibreglass,and
it is a personal choice as to which you choose,
the myth with pvc liners is that they will crack after a couple of yrs but the reality is the modern
pvc liner is uv stabilised and come with 15/20 yr or in the case of ours a lifetime written guarantee
so installing one is not the risk you are led to believe,and can give years of use providing it is
installed correctly,rubber liners actually have a shorter life span than pvc despite being much more
expensive to purchase,
G4 is a brand of plastic paint that we have used for years and is an alternative to fibreglass but much
cheaper to use,
fibreglass is classed as the ultimate finish,but the reality  is it  depends on the installation and is also the most expensive of all the options,but can be unreliable if installed badly,
tomorrow i will explain the  pros and cons of each one,

is it here yet

well what can i say,is summer here at long last,or is this another
lull before the storm,lets not be negative and enjoy the sun while
we can so now is the time to rush out and get that pond cleaned
up and pull the weeds out,because i seem to be able to grow weeds
better than flowers,
  at least we can get a bit of quality time around our ponds,if you
are like us,the fish seem to be thriving and have not been put off
by the cooler weather,they have certainly put on body wait and all
look fit and healthy [if i dare tempt providence],maybe now is the
time to purchase that new addition to the pond while we still have
time to get it beefed up ready for winter,
regards paul
