What is Polymeric Sand?
While there is a scientific
formula behind the name, this is a rather basic staple in the construction
industry and common when it comes to the creation of pavements or general
brickwork. That being said, this is also a rather simple explanation so let us be
Bit what is Polymeric Sand exactly?
Polymeric sand is a substance
which is used to solidify the joints between pavement, brickwork, and any
concrete based structure. Combining sand and several finite substances
including silica, polymeric sand acts as a binding agent between two pieces of
concrete. However, the sand must be used in conjunction with water in order to
Advantages of using Polymeric and
any kind of sand can be used to fill in the gaps but polymeric sand leaves no
trace or marks meaning there are no stains to clean after using this particular
agent. At the same time, there are other advantages to using polymeric sand as
Threat posed by heavy rain When using standard sand, heavy rain can pose a serious threat in that
it washes away the sand before it sets into place. Alternatively, polymeric
sand is not as penetrable which makes it less likely to be affected by heavy
Polymeric Sand is stronger The binding
nature of polymeric sand mean it is a much stronger solution to hold pavers
together and this is certainly true regarding the longer term.
Added variety Interestingly, polymeric sand
comes in a wide range of colours which means you can choose one to suit the
intended color of the brickwork n question.
More resistance to weeds Plants are
a common p in for patios in particular are they crop up between most cracks.
However, polymeric sand is more resistant and less kind to the growth of plats
which means you can spend more time sitting on the patio and less time picking
out the weeks.
Further resistance to insects Likewise,
polymeric sand is less attractive to ants and other insects who like to inhabit
the cracks in between.
Using Polymeric Sand is a simple process

Having laid down the concrete or
brickwork, simply brush the polymeric sand in between the cracks. Afterward, it
is important to also brush any loose sand away from the surface of these
bricks, otherwise this will harden once water is added to the solution. In this
respect, a small leaf blower is useful for getting rid of the unwanted grains
of sand. Lastly, take a garden hose and lightly spray a mist-like cloud across
the area which will activate the polymeric sand to act as a binding agent.
Tips for getting the process right
However, using polymeric sand may not be the answer to your prayers if
you dont use the following tips:
You must lay the pavers in a
straight fashion before using anything to bind them. For example, it is easily
possible to solidify the pavers when they are out of sync which entirely
defeats the purpose. Moral of the story: Make sure the ground is level and pavers
are set the way you want them before adding any polymeric sand.
If you are using polymeric sand
for the purpose of avoiding stains then it might be best to avoid using red
brickwork as this stains easier than any other.
Use some plastic to temporarily
cover and protect the pavement when finished, especially if there is traffic or
a lot of movement nearby.
Ensure the pavers are properly
wiped down and clean of even dust before adding the binding agent.
As mentioned above, lightly
spray the area but do not use too much water or the agent and polymeric sand
will begin to run away from the intended place of binding.
Where can you find Polymeric Sand?
Most suppliers who provide pavers
will also provide polymeric sand so you should always as at the point of
purchase. However, in the event of this not being available, you should find
that most stores for home improvement will sell polymeric sand in either twenty
or forty pound bags. Although there are different brands, most of these are the
same and do exactly the same job.
As you can see, there is little
to know about polymeric sand but this binding agent is a crucial component to
combine pavers and should always be used for the best long term solution.
