Proizomastik 5022

Proizomastik 5022 Surface Preparation and Application Guide

Surface Preparation

  • The surface must be dry, clean, sound, and free of dust.

  • Oil, dirt, or anti-adhesive materials must be cleaned from the surface, and substances like mortar and cement residues must be scraped off.

  • The moisture content of the surface should be a maximum of %5.

  • New concrete structures should be left to dry for a minimum of 28 days.

  • While Pro Mastik 5022 provides excellent adhesion to many surfaces even without using a primer, the surface-preparing Pro Mastik 5022 primer should be used on joint edges depending on the surface type in cases where the surface cannot be completely freed from dust or in places that may be exposed to high mechanical impact.

Application

  • The Pro Mastik 5022 sausage product must be placed inside a gun with a suitable nozzle, and the tip of the gun must be cut at a $45^{\circ}$ angle.

  • It should be squeezed continuously and slowly, ensuring that Pro Mastik 5022 completely contacts the joint edges and leaves no air gaps inside.

  • After filling the surface, Pro Mastik 5022 should be smoothed by pressing lightly towards the joint edges without overflowing, and its adhesion to the edges should be ensured.

Category:
  • It is a polyurethane-based, single-component, low-modulus polyurethane joint filler mastic with high elasticity for building joints.

Advantageous Features

  • It has high resistance to outdoor weather conditions and negative effects.

  • It is suitable for use in joints with a movement capacity of up to %25.

  • It should be preferred especially in expansion joints due to the minimum resistance it applies to the surface.

  • It has UV resistance.

  • It is not affected by temperature changes and chemical substances, and it cures without bubbles.

  • It preserves its elasticity for many years without loss of volume.

  • Paint application can be made over it.

  • It is ready to use and quick and easy to apply.

Areas of Use

  • Pro Mastik 5022 is used to fill expansion joints of buildings and heavy structures in a leak-proof, permanent, and elastic manner.

  • It is used to prevent leaks especially in precast element joints, roofs, connection and joint places of rain gutters and rainwater pipes, and antenna and chimney bases.

  • It is used on horizontal and vertical surfaces in indoor and outdoor spaces.
