Thin polymer modified screed and screed repair mortar


Ronafix Pre-packed Screed 6-50mm is supplied as a pre-packed, two component, ready to use mortar for laying floor screeds. Ronafix Pre-packed Screed 6-50mm is supplied complete with all the correct dry components in a bag and a bottle of polymer gauging liquid. Ronacrete Standard Primer two part polymer cement bonding agent is required for bonded screed applications.


Ronafix Pre-packed Screed 6-50mm is used to lay new screeds and toppings as thin as 6mm for light duty bonded and 35mm unbonded or floating applications. Screed thickness should be increased for medium to heavy duty use,  Excellent adhesion can be achieved to suitably prepared surfaces and the screed is resistant to water, frost, and medium to heavy wear.

  • Improved strength gain 1-day strength > 30N/mm²
  • High ultimate strength > 55N/mm² after 28 days
  • Suitable for wet areas
  • Suitable for exterior application
  • Suitable for application to falls
  • Greater durability, tensile and flexural strengths are maintained for decades longer than in traditional screeds
  • Reduced minimum thickness for bonded, unbonded and floating screeds, may be applied as thin as 6mm when bonded and use in light duty applications
  • Low water absorbency, making screeds resistant to frost attack.  Will not allow passage of water under hydrostatic pressure
  • Reduced shrinkage
  • Suitable for use as a medium to heavy duty wearing surfaces (wear resistance AR1 to BS EN 13813:2002)
  • Slip resistance PTV ˃ 55 dry, ˃ 44 PTV wet
  • Suitable for use on high rise multi-occupancy buildings.  Classification of reaction to fire BS EN 13501-1 A2-s1, d0
  • Faster drying than traditional screeds and calcium sulphate screeds
  • Compatible with resin floorings, unlike traditional screeds and calcium sulphate screeds
  • Superior corrosion protection of embedded steel; calcium sulphate screeds are not compatible with embedded steel
