weberfloor industrial base 4600 is a rapid setting, self-smoothing base screed for industrial areas. It levels highly irregular concrete floors from 5mm to 30mm and makes them ready for a Weber industrial top screed, weberfloor industry pro top 4610 or weberfloor industry rapid 4655, much earlier than a traditional sand and cement or concrete screed. It is ideal for renovating existing floors with large irregularities.

Key benefits

What you need for the job

• Primer: weberfloor 4720 epoxy primer, Weber's choice for industrial construction and also suited to moisture-sensitive surfaces, or weberfloor 4716 primer
• Top screed: weberfloor industry pro top 4610 or weberfloor industry rapid 4655
• 10 x 100mm edge foam, and weberfloor 4965 barrier foam for bays and stop ends
• Hollows over 30mm in small areas: two layers of 4600, the first hardened and primed before the second (12 hours between layers). For larger areas Weber recommends weberfloor 4360.

Mixing

4.5 litres of water per 25kg bag (18%). Pot life 20 minutes at 20°C. Do not add more water: it lowers strength, increases shrinkage and makes the mix separate.

Coverage

Approx. 1.85kg per m² per mm. One 25kg bag covers about 2.7m² at 5mm or 1.35m² at 10mm (calculated from the Weber figure).

Good to know

• A base screed only: it is not a wearing screed and must be covered with weberfloor industry pro top 4610 or industry rapid 4655. Never paint it or leave it bare.
• For use inside buildings.
• The concrete needs a surface strength above 1.5 N/mm² and relative humidity below 95%.
• Keep the substrate and the air between 10°C and 25°C while laying and for at least a week after, with no draughts for 3 days.
