Application
- Pour the contents of the container with component B into the container with component A. For partial application, ratio of the components should be A: B-100: 40 by weight. Use an electric or pneumatic agitator, 400 – 600 rpm. Mixing time is 2-5 minutes.
- If using an injection method, then fill the hole or the cavity (for example, between the sleeper and the formwork) with PUMA – V, or pour a leveling layer of the required thickness. Filling thickness should be at least 15 mm and a maximum of 60 mm.
- Solidification time is 72 hours.
- Clean the tools with organic solvents (acetone, xylene) once work is complete. Clean the tools from dried materials mechanically.
Health effects and precautions
Follow and observe safety regulations in accordance with SNiP III-4-80. Use personal protective equipment: a gas mask or protective mask, special clothing including gloves and shoes, covering all parts of the body.
Storage recommendations
Shelf life 6 months at temperatures no lower than + 10 and not higher than +30 °C in the closed original packaging.
Problem solution
Problem:
Presence of bubbles, cavities, untreated or brittle areas on the surface, and ingress of dirt particles during the filling.
Solution:
- Remove the defective area with a sander.
- Clean the base.
- Re-fill the PUMA-V layer.
