Application

METHOD OF APPLICATION

PREPARATION

• Surfaces must be very clean and dry, degreased and free of friable particles that could hinder adherence. You can use acetone, alcohol or degreaser to clean the substrate.
• Check the compatibility of the Neutral Silicone Ultimate MF Chemisil with the substrates and, if necessary, apply a primer.

APPLICATION

• If necessary, use joint cord to avoid three-point contact and observe the width/depth ratio defined by the following general rule: ideal joint depth = joint width / 2, with a minimum depth of 6mm.
• The application temperature must be between +5°C and +40°C.
• If necessary, apply masking tape to the sides of the joints to protect the places where it should not come into contact.
• Cut the tip and place it in the cartridge. It is recommended that this cut be made at 45°C, in the diameter required for sealing the joint.
• Ultimate MF Chemisil Neutral Silicone can be applied with a manual or pneumatic spray gun.
• Apply the product in uniform and continuous strands for sealing. After application, use a spatula to smooth the joint with soapy water and remove the masking tape before forming a film. It is very important to press the sealant well against the surface to be sealed.
• The curing process starts when it comes into contact with the humidity in the air, which is done from the outside to the inside 2mm every 24 hours.

CLEANING

• Tools can be cleaned with acetone before the sealant cures. After curing, it can only be removed by mechanical action.

PAINTING

• Cannot be painted.
