9 months from date of manufacture.

Feb® Febtank Super Tanking Slurry should be stored under cover and clear of the ground.  For bags stack no more than 6 high. Protect the materials from all sources of moisture and frost. Store between +5 to +30 °C.

Bulk - 1.25 g/cm³

Wet mixed - 2.06 - 2.07 g/cm³

30 mins at +20 °C.

+20 °C - Approx 6 hours.

3.5 kg/m² for a two coat application (1 mm/coat). Increase to 7 kg/m² for areas of excessive water pressure.

Mixing should only be done by hand or via slow speed drill/paddle (400-600 rpm). Gradually add powder to water whilst mixing at a rate of 25 kg powder to 4.5 – 4.7 L water (20 kg powder to 3.6 – 3.8 L water) to achieve a thick creamy lump free constancy. Leave to stand for 10 mins prior to applying. Remix and add a very small amount of water if required to restore original consistency. Never use more than 5.4 L (4.3 L for 20 kg) of total water. Mixed material must always be used within 30 minutes, or less under hot weather conditions.

Note: Do not apply Feb® Febtank Super Tanking Slurry to frozen substrates or if the ambient temperature is below +5 °C or expected to fall below +5 °C within 24 hours. Avoid application in direct sunlight. Always apply the mix to a pre-dampened surface.

All work must be carried out in accordance with BS 8102.

Feb® Febtank Super Tanking Slurry is a minimum two coat application system.  Always dampen surfaces to aid adhesion. Remove all free standing water prior to application.  Apply by stiff brush or broom or with traditional mortar spraying equipment. The actual thickness per coat must be between 1.0 and 2.0 mm. Normal application rate is 3.5 kg/m² for an overall two coat application. Increase to 7 kg/m² for areas of excessive water pressure.

Applying the first coat: Brush or broom the mix firmly onto the pre-dampened, prepared surface. After completing 2 or 3 m² finish with the brush or broom in one direction for aesthetic purposes. Care must be taken not to spread the material too thinly. When the material begins to drag or “ball”, do not add more water, but dampen the surface again.

Applying the second coat: Allow at least overnight to cure before applying subsequent coats. Ensure first coat is firm to touch. Dampen the first coat and remove excess moisture. Apply the second coat at right angles to the first coat to ensure good covering.

NOTE:  If Feb® Febtank Super Tanking Slurry is used in closed, poorly ventilated rooms, condensation may occur on the first coat. This condensation must be removed from the surface.  Feb® Febtank Super Tanking Slurry can be spray applied but should always be brushed home to give a uniform surface.

ALWAYS fine mist spray all the treated area as soon as initial set has taken place and for as long as is possible  In cold, humid or unventilated areas (e.g. cellars) it may be necessary to leave the application for a longer curing period or to introduce forced air movement. NEVER use dehumidifiers during curing periods.

SUBSEQUENT OVERCOATING: Feb® Febtank Super Tanking Slurry is suitable for overcoating once correctly and thoroughly cured.

Plaster: If plaster is to be used it must be ensured that cement based “renovating plaster” is used. Gypsum plasters must not be used.   

Cement based render: Use a slurry bonding coat consisting of 2 parts sand, one part cement gauged to a brushable paste with neat FEBBOND SBR. Apply render whilst bonding coat is still tacky.

Final Decoration:  Allow 6 months minimum to elapse before final decorative finishes are applied.
