SULPHATE RESISTANT BLOCK & BRICK LAYING MORTAR
Made of sulphatre resistant cement, graded sand and additives - a ready mix mortar that when blended together creates an improved workability, better-quality bonding and excellent water retention.
The use of sulphate resistant cement provides the mortar with enhanced durability and resistance when used in environments prone to chloride and sulphate attacks.
NEOFIL BLS reduces shrinkage and movement in masonry walls due to a controlled elasticity modulus.
Packaging
NEOFIL BLS is supplied in 50 Kg bags
Storage

Surface preparation
The blockwork where NEOFIL BLS will be applied must be perfectly clean, solid, compact and free from grease substances or solid particles. It must not be over-heated nor frozen.
During hot water weather, the surface to recieve NEOFIL BLS should be brushed with water prior to application. Take extra note to neutralize the suction in the background to the blockwork by applying clean potable water. Allow excess water to be fully drained before applying NEOFIL BLS.
Mixing
To prepare the mixture, pour in a container 6-7.5 liters of clean water. Add a bag of 50 Kg of NEOFIL BLS, then mix to get a homogeneous lump free consistency mixture using an electric agitator / slow speed mechanical mixer.
Once mixed, let the product rests for about 5 minutes and remix shortly before use.
Application
Apply NEOFIL BLS using a trowel and then position the blocks verifying their alignment. Remove possible excess of mortar with a wet sponge before it hardens.
Curing
Protect the newly applied material from direct exposure to sunshine and wind and allow to be cured for at least 3 days by spraying with water 3 to 4 times daily.
Cleaning
Tools and equipment should be cleaned with water immediately after use. Hardened materials should be mechanically removed.
Recommendations
NEOFIL BLS is a cement - based product. Avoid contact with skin or eyes. Provide adequate ventilation in working place to avoid inhalation of dust.
During application, wear appropriate protective clothing, goggles, gloves and respiratory equipment of necessary.
In case of contact with skin, rinse with water and again wash thoroughly with soap and water. In case of contact with eyes, rinse with plenty of water and seek medical advice accordingly.
