ABOUT

Firestop acrylic mastic ALFA MASTIC effectively fills gaps around pipes and cables in service penetrations, apertures and linear joints in plasterboard, masonry, concrete, reinforced concrete partitions.

ALFA MASTIC is an intumescent mastic sealant that expands on exposure to high temperature, preventing passage of fire, smoke and gas.

The width and depth of the sealing depends on the application.

In very humid places and highly movable apertures, use ALFA FLEXI MASTIC.

 

ALFA MASTIC is intended to seal penetrations for:

  • PLASTIC PIPES
  • STEEL AND COPPER PIPES
  • SYNTHETIC RUBBER-INSULATED PIPES
  • SINGLE CABLES AND CABLE BUNCHES
  • VENTILATION DUCTS
  • as well as gaps and linear joints in plasterboard, masonry, concrete, reinforced concrete walls and floors.

INSTALLATION

1. PREPARATIO

a. Do not use ALFA MASTIC, when the ambient temperature is below 5°C.

b. Before applying mastic, you should thoroughly clean the surfaces of grease and other contaminants. Mass should not be used on substrates that produce oils, plasticizers or solvents.

c. ALFA MASTIC is a water-based product. In situations where there is a risk of corrosion, corrosive elements must be properly secured before they are installed.

d. To prime the surfaces of the gypsum boards, edges can be moistened, or use diluted, with water, ALFA MASTIC.

e. In case of fire seals, before application of ALFA MASTIC, it is necessary to identify the type of seals (single-sided / double-sided, horizontal / vertical), type of construction, the crossings elements and the required value of EI. Follow the detailed installation instruction.

2. APPLICATION

a. The minimum width of the seal is 10mm. Make sure that the sealed gap is wide enough to accommodate the required foundation. As a foundation is recommended to use mineral wool.

b. Cut the wool so that it tightly enter the gap and came to proper depth.

c. Fill the gap with ALFA MASTIC to the required depth (for sealing type / type of structures / elements of crossing/ desired EI value)

3. FINISH

a. Finish with stopping knife.

b. ALFA MASTIC can be painted with most emulsion and alkyd paint.
