Nvirodry home protection
When walls get wet they get cold as well...which means the heat escapes from a building more easily making your home colder. Older properties with solid walls can not be insulated internally to stop the heat loss and external insulation can be extremely expensive and quite often impractical. Nvirodry waterproofs the walls, stops rainwater penetrating and therefore reduces the heat loss. It also reduces frost damage because if water is not allowed to penetrate the walls it cannot freeze & cause spalling of the bricks. Penetration of rainwater is becoming more and more of a problem as our weather gets wetter and wetter. Even properties built in the 1960s and 1970s constructed with poor quality bricks can suffer badly from spalling of the bricks caused by frost damage.
Water based for use on dry or damp walls
Reduces heating bills
Penetrates deep into the substrate
Superior performance to solvent based systems
Protects against dust, dirt and efflorescence
Nvirodry not only waterproofs, but protects brickwork against rain, damp and frost damage. It is fast acting and lasts, prevents water penetration whilst being permeable to water vapour and gases. Unlike solvent systems Nvirodry CAN BE USED ON DAMP WALLS. Heat loss through a wet wall can be 3 times more than that of a dry wall, Nvirodry prevents the rain from penetrating the wall. Heat loss through walls can be as much as 35%.
Walls and floors in external and internal applications. Ideal for porous substrates such as stonework, brickwork and untreated concrete. Can be used on patios and paving slabs to help with cleaning.
Nvirodry is clear and colourless and will not normally
alter the appearance of treated surfaces. In some
circumstances, however, very slight darkening may
