Screed Additives

AptiScreed Max

AptiScreed Max is a unique, innovative liquid screed admixture combining next generation technology for rapid drying times and high early strengths.

Applications

AptiScreed Max is a liquid admixture for semi-dry screeds which has been specifically developed to provide rapid drying times, high early and ultimate compressive and flexural strengths in bonded, unbonded and floating screeds. It is ideal for underfloor heating, internal and external applications.

Benefits:

  • High early compressive and flexural strengths.
  • Allows foot traffic after 24 hours.
  • Very rapid drying times.
  • Produces a Cat A, C40, F7 Screed, allows thinner screeds to be laid without compromising strengths.
  • Compressive strengths of up to 60N/mm² can be achieved.
  • Ideal for underfloor heating.
  • Internal and external applications.
  • Bonded screeds from 20mm and 35mm for unbonded screeds.
  • Improved finishing from action of superplasticiser.
  • Low odour, low VOC content.

Usage

Care should be taken not to over water the mix. Bear in mind that sand can be supplied with a high-water content. The correct consistency is such that the material should be semi-dry so that a ball can be made that will be firm but that no water can be squeezed from it.

AptiScreed Max is supplied in 20L, 200L drums and 1000L IBCs. 12 months minimum shelf life when stored at normal temperature in dry conditions.
