Description

Dryvit ACR systems are a range of 100% acrylic polymer based anti-crack renders designed to out-perform the shrinkage and cracking characteristics of traditional renders. The range offers a variety of coloured and textured coating options providing various levels of protection when used in the different component combinations. Dryvit ACR systems are generally installed over a Dryvit polymer modified re-profiling mortar where levelling is required, on to exterior concrete, brickwork, blockwork, plastered or painted surfaces in new build or refurbishment projects. Commonly applied over timber or steel framed substrates incorporating an approved sheathing and breather membrane in new build residential and low-rise commercial projects.

Benefits:

  • Crack resistance. Location and frequency of movement joints is greatly reduced or even eliminated compared with that of traditional renders due to the high performance crack resistance of our systems.
  • Weatherability. Dryvit systems are formulated to provide the utmost in weather protection providing a resilient barrier against wind and water.
  • Durability. The combination of system components provides unsurpassed long-term durability meeting design requirements for use in virtually any location.
  • Aesthetics. Dryvit finishes are available in a wide array of textures in both standard and custom colours. The speciality finishes enable designers to replicate a variety of real stone or brick finishes from limestone to granite at a fraction of the cost.
  • Testing. Independently certified by BBA and other international test bodies. Dryvit manufacturing plants are ISO 9001: 2000 certified, demonstrating the highest standards of quality and consistency.

Product Options

Pretreatment:

Consult with Dryvit for details of preparation to suit project substrate. Use fungicidal wash by system manufacturer. If required, specify in 'Structural substrate' clause.

Finish:

  • Dash receiver and dash aggregate: Ready to use blend of polymer modified dry powders which only require the addition of potable water to produce a high performance receiver for Dryvit's range of dash aggregates.
  • Drytex: Dry cement based mixtures enriched with synthetic resins which after being mixed with water give a high quality textured finish. Drytex finishes are white with the final fade resistant colour achieved by over-coating with either Demandit or Silstar façade paints.
  • FDPMR: Premixed 100% acrylic finish containing DPR and PMR technology as well as a film forming accelerator for improved resistance to wash off.
  • HDP: Proprietary, silicone based technology textured finish which promotes hydrophobicity enhancing reduced dirt pick up properties.
  • PMRB: Aggregate textured 100% acrylic-based proven mildew (PMR) and dirt pick resistance (DPR) finish.

Brick effect finish or other from speciality finish range are also available, consult with manufacturer for details.

Accessories:

  • Dryvit drainage strip.
  • Expansion/ movement joints: Will be required to reflect such joints in the existing wall plus any movement joints to reduce the risk of cracking in the render finish. Consult with Dryvit for recommendations for type and location.
  • Demandit is a 100% acrylic coating which is offered in a variety of standard colours and custom colours. Demandit contains the most effective ingredients available to help resist mould and mildew growth (PMR)
  • Silstar is a façade paint produced on the basis of silicone and acrylic resins. The coat created following the use of Silstar is characterized by a high degree of vapour permeability. It fully protects the surface from atmospheric conditions as well as development of micro-organisms after complete drying and gives the surface a pleasant appearance.
