The conventional
method of sandblasting pools is the way of the past.
We have removed up to 3 inches of marcite
very efficiently with ultra-high pressure waterblasting.
Sandblasting converts previous pool coatings into a fine dust that
carries throughout the surrounding neighborhood, contaminating the
air we breathe. Not only does this present a health hazard, but it
also coats cars, collects in the sliding tracks of windows and doors,
ornamental flowers and landscaping; even seeping through the open windows
of neighboring homes. Sandblasting literally affects everything within
a certain radius of the pool. The size of the radius depends on the
wind speed of the particular day when blasting occurs. Think for a
moment of the liability involved when spewing this kind of dust into
the air around your home. Hydroblasting is by far the best method of
preparing swimming pools for a new finish.
Consider these
factors when making your choice. Keep in mind the inevitable "mess" you
will experience no matter which method of removal you choose.
(1) With waterblasting, there is no airborne dust. All particles
or materials being removed are saturated and the law of gravity
brings them to the ground quickly.
(2 )There is no added abrasive waste (Sand) to be cleaned up and
disposed of.
(3) For residences with screened enclosures, we utilize a tarping
system to contain the debris within a tent-like structure. It is
quickly erected and disassembled.
Notice the precision with which the waterjets
can cut. Shown here within ¼" of the tile.
This system saves the screened enclosure from the whitish cast that
would develop otherwise. With sandblasting, however, even if this tarp
were to be used the warm air generated by the compressed air would
carry the dust out from under the tent and into the surrounding areas,
inevitably coating the screens. In some cases with waterblasting, there
will be small portions of screens that experience a temporary whitish
cast for a short period of time. Should the condition persist, Waterblasting.com
Inc. will remedy the situation for the customer in a completely satisfying
way.
(4) Probably the greatest advantage to using waterblasting with pools
is the vast difference in hydraulic pressures between sand and water.
We use 40,000 p.s.i. waterjets when hydroblasting pool surfaces. Sandblasters
use approximately 150 p.s.i. of air pressure. That is a difference
of 39,850 p.s.i. There is also the added difference between air and
sand traveling at approximately 6.25 miles per hour, and water being
expelled at speeds of 1,500 miles per hour. At this rate, sandblasting
will effectively remove the unwanted coatings.
However, waterjets at 40,000 p.s.i. will remove the coatings while
at the same time removing any inferior marcite or concrete that lies
beneath them. This prevents you from wasting time re-coating a partially
deteriorated surface, which will not maintain a strong bond. Because
of the constant pressure, waterjets seek out and destroy all inferior
surfaces in your pool and insure that whatever new surface you choose
to apply, it will remain there for a very long time. If getting the
job done right the first time matters to you, give us a call today
