ADVERTORIAL
Your Conservatory Installations
are under attack from
Rain and Sun
Bricks and mortar are
like moisture reservoirs
that fill during a rain
event – they wick
water into themselves
because they are porous.
Properly built brickwork
will give many years of
trouble free service, but
add an extension or
conservatory onto an
exterior wall and there
could be trouble ahead.
Water vapour travels inward along the
temperature/pressure gradient.
The vapour will then condense back into
a liquid, running down the back side of
the airspace and into the conservatory.
The problem is both rain and
The SoluTion is to apply
sun together can exacerbate the excessive
moisture in walls and cavities. Wind
driven rain will track by capillary suction
into dryer areas of brickwork. Solar
radiation heats saturated brickwork and
will drive moisture vapour inward as well
as outwards.
A higher vapour pressure and temperature
differential forms between the cavity and
cool interior, drawing in the moisture
vapour, which will then condense into
liquid and present as damp spots within
the extension interior surfaces.
ProShield XT water repellent masonry
treatment to the exterior masonry walls.
It’s quick & easy to apply and being water
based, is environmentally friendly with
no VOCs. It does not seal the masonry
structure but penetrates deeply, to provide
breathable, invisible protection from
damaging water ingress - maintaining
masonry appearance whilst reducing
the risk of penetrating water damp and
mould within the interior of a building.
