Ronabond® Floor Screed HD

Polymer Modified Pre-bagged Waterproof Floor for Heavy Traffic

Ronabond® Floor Screed HD is a prepacked SBR polymer modified mortar. It is used to repair or relay areas of concrete floor which are damaged, worn or eroded as a result of wear, impact or attack. The cured mortar bonds securely to suitably prepared surfaces, is waterproof and is available as a screed of a topping material. It is used in industrial, commercial and residential premises to repair and resurface floors in thin or thick section to provide a hardwearing and durable screed for floor finishes or as the wearing surface. Ronabond® Primer is used to provide good adhesion between the mortar and the substrate. Careful surface preparation is essential to ensure adhesion and performance.

Application steps

MIXING

Ronabond® Floor Screed HD should be mixed in a forced action mixer or using a slow speed drill (typical 500 rpm) and paddle. Place the whole bag of powder in the mixing vessel, add maximum 16 kg 5–10mm aggregates if the application thickness is over 25 mm. Pour the whole drum of gauging liquid into the mix. Mix for two minutes to achieve a homogeneous workable mortar.

APPLICATION

As soon as the material is mixed place it onto the wet/tacky primer, compact, rule and close with a float or trowel. Avoid overworking the surface. Ronabond® Floor Screed HD should be used for vehicle traffic with thickness over 25 mm.

  

Finishing and Curing

Finish the surfaces to the desired profile using a wood or steel float or trowel. After finishing the surfaces should be cured using Monocure 50 or by covering with close contact polythene sheeting for at least three days.

CLEANING OF TOOLS

Clean all tools and equipment with clean water immediately after use.
