Surface preparation

The blockwork where NEOFIL BL 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 weather, the surface to receive NEOFIL BL should be brushed with water prior to the application. Take extra note to neutralize the suction in the background of the blockwork by applying clean potable water. Allow excess water to be fully drained before to applying NEOFIL BL.

Mixing

To prepare the mixture, pour in a container 8 - 9.5 liters of clean water. Add a bag of 50 Kg of NEOFIL BL, 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 BL a trowel and then position the blocks verifying their alignment. Remove possible excess of mortar with a wet sponge before it hardens.

Cleaning

Tools and equipment should be cleaned with water immediately after use. Hardened materials should be mechanically removed.

Recommendations

• If the blocks are laid directly on a floor with possible humidity rising, it is recommended to apply a proper damp course system first.
• The 2 cm separation between the top of the block wall and the bottom of slab or beam should be filled with suitable compressible material.
• Spray the block wall with water before applying the plaster.
• Ensure that the first layer of blocks is fixed proper with perfect alignment.
• Do not apply NEOFIL BL in rainy weather, high winds and sand storms.
• Do not apply on surface that has temperature less than +5ºC.
• During summer season, working area should be covered to prevent the direct sun effects. Keep equipment cool and use a cool water.
• The product should not be exposed to moving water during application.
