Instructions for use Preparation

It is essential that the primer is applied to a sound, clean and dry substrate in order to achieve the maximum adhesive bond and long term durability.

Mixing

 

Mix both components till a homogeneous mixture is obtained. It is important that both components are intermixed thoroughly and that no traces of the components remain unmixed.

Application

 

When mixed the primer should be applied immediately with a roller, brush or spray in a thin continuous film. Care should be taken to avoid over application or puddles. If the existing substrate is very porous a second coat may be necessary.

Cleaning

 

Nitoprime SP should be removed from tools and equipment with Fosroc Solvent 102 immediately after use. Hardened material can only be removed mechanically.
