 Possesses outstanding strength and adhesive powers

 Resistant to physical damage

 Excellent chemical resistance

 Can be used underwater

Description

Nitomortar UA is recommended for fixing slip bricks and for

reinstating structures exposed to heavy battering from the

sea, such as sea walls and concrete jetties and for repairing

submerged steelwork and concrete. Mixed mortar may be

transported underwater in polythene bags.

Application instructions

Mixing Nitomortar UA

The 1.5 litre pack of Nitomortar UA is suitable for hand mixing

(wearing protective gloves) on a flat, clean surface. The mixing

surface should be wetted and the whole of the base material

spread out approximately 10 to 20 mm thick. All of the hardener

should be emptied out onto the middle of the base and the

base folded over the hardener and kneaded until the resultant

mortar is of an even consistency and uniform colour.

Underwater application

Surfaces must be mechanically cleaned, free of weak or loose

material, marine growth, rust, scale, etc. Mixed Nitomortar

UA should be carried in plastic bags to work area and small

quantities, approximately 5 mm thick, pressed into position

ensuring that all water is expelled from between the repair

surface and the Nitomortar UA. Mixed mortar should be

applied within 30 minutes of mixing. Contact between the

mixed mortar and water should be avoided until the point

of application. Uncured material should be protected from

scouring and displacement by moving water until cured.
