Product Features

Wall Dry 2R is a heavy duty water repellent clear sealer, a blend of Siloxane Silicon resin.

With 2 extremely durable weatherproof solvent based resins that give protection to driving rain and the effects of acid rain.

Ideal for older buildings, where a stabilised bonded and sealed breathable surface is required.


Suitable for stone, masonry,brick, mortar, concrete, period clay roof tiles, Rosemary and terracotta tiles.


Advantage 1 - Solvent based can be used in all weather conditions

Advantage 2 - Reduces spalling or flaking masonry

Advantage 3 - Ideal for sandblasted stone and brick that has become porous and flaky

Advantage 4 - Excellent for new concrete to give a long lasting weatherproof transparent surface

Advantage 5 - Has a low surface tension, making it very invasive so enabling it to penetrate well into the surface up to a depth 10mm

Advantage 6 - Acid and alkaline resistant and is unaffected by salt spray

Advantage 7 - Does not change the breathing characteristics (circulation of air through the wall)


Application should be made at the rate of 1 to 2 square metres per litre for the 2 coats depending upon porosity.


Dense masonry may not accept Wall Dry 2R at this rate. Such surfaces should be given two coats and the coverage. Extended to 1.5 to 2 metres per litre. At least 1 hour should be allowed between coats.


Conforms to British Standard BS6477 (1984) - Water Repellents for Masonry Surfaces.


Supplied in 20ltr resealable UN containers.
