Leoseal R is an economical flexible waterproofer and crack
sealant designed for easy hand application.
Leoseal R is a specially formulated combination of bitumen
emulsion modified with an elastomer which together form a tough and
long-lasting barrier against the entry of water.
Leoseal R has excellent adhesive properties and can be applied
to green concrete or damp surfaces.
Where to use?
- Waterproofing below ground concrete structures
- Crack sealant for roads and footways
- Work should not be carried out in wet or frosty weather
- Surfaces must be dry or damp (no standing or running water) as
well as clean and free from dust, oil and fuel spillage
Apply Leoseal R in two coats using a turks head brush. The first
coat should be at a rate of 0.55lts per square metre with the
second applied at right angles at a rate of 0.45lts per square
metre. (If the surface is hot, very dry or absorbent it may be
helpful to first prime the surface with a thin coat of Leoseal R
diluted in a ratio of 1 part water to 8 parts Leoseal R).
When finished, wash brushes with Leoclean immediately followed
by soapy water.
When backfilling is necessary the Leoseal R treatment should not
be left longer than 3-4 weeks before this is undertaken.
Cracks up to 3mm Pour the emulsion into the crack using a
Any surplus on the surface should be brushed or squeegeed out to
a thin film and dusted over after drying with cement or very fine
sand to remove the tack.
Cracks 3mm - 25mm
Prime the sides of the crack with a brush-coat of emulsion.
Fill the crack with a mortar made by mixing Leoseal R with fine
damp sand in the ratio of 1 to 1. Compact the mortar into the
crack, and smooth off the surface with a trowel.
After drying, apply a brush-coat of the emulsion, and blind
this, after drying, with cement or sand
N.B: Leoseal R sets by the evaporation of water from the
product. Application should only be carried out in good drying
conditions. A rain resistant set will be delayed if the weather is
cold, damp or humid.
Protect from frost.
