Hydraseal Slurry

Uses

• basements
• sewage tanks
• reservoirs, canals and swimming pools
• water towers and silos
• subways and manholes
• precast concrete units

Advantages

• pre-blended (no bonding liquid required)
• easy application – applied by block brush
• block water passages – seals pores
• can be applied to wet surfaces or green concrete
• non-toxic and non-tainting

Mixing

• mix 1 x 20 kg DAMPZERO HYDRASEAL SLURRY to 7.2 litres of water to produce a suitable brush-on mixture
• DAMPZERO HYDRASEAL SLURRY is supplied in a 20 litre container suitable for mixing purposes – just add water
• occasionally stir the slurry to prevent settlement of solids
• DO NOT re-temper the slurry once it has started to set

Application

• if there is exposed reinforcement within the treatment area, coat with WJ BONDCRETE to ensure sound bonding is achieved
• ensure free standing water is removed before commencement of application
• presaturation of the area is advised before application
• apply 2 x coats of DAMPZERO HYDRASEAL SLURRY, one coat at a right angle to the other
• allow 12 hours curing time between each coat

Recommendation

• use rubber or plastic gloves to protect against cement burns
• where possible, protect the newly treated surface from frost or rain
• application should not cure too rapidly; treated area should be kept damp for 2-3 days
