Application Notes

• All coating work to be carried out in accordance with the relevant sections of BS6150:2019, Painting of Buildings - Code of Practice
• It is essential to produce an unbroken coating of Dekguard A Plus
• To ensure this is achieved, surfaces containing blowholes or similar areas of pitting should first be filled using Renderoc FC, a cementitious fairing coat. Depending on the thickness required, rougher substrates can be levelled using Renderoc ST05, a protective cementitious coating, or Renderoc RP252 cementitious reprofiling and protection mortar
• A priming coat is made up on site by diluting Dekguard A Plus as follows:
  
  • Stir material before use then using suitable volumetric containers, measure 1part Dekguard A Plus and 1 part drinking water by volume into a clean bucket
  • Mix with a paint stirrer until a uniform thin consistency is obtained
• Under no circumstances should the primer be overcoated until the surface is fully dry
• Rough Surfaces:
  • Where Dekguard A Plus is to be applied to rough substrates, e.g. exposed aggregate surfaces, apply the priming coat as described above
  • After drying, apply 3 coats of diluted Dekguard A Plus, made up of 3 parts Dekguard A Plus to 1 part water by volume at a wet film thickness of 150 microns
  • Between coats the typical drying time is 6 hours in dry weather at 20°C

Please see the Product Data Sheet for detailed information.

Limitations

• Application of Dekguard A Plus (or the diluted primer coat) should not proceed if the air or substrate temperature is 5°C and falling (at a steady 5°C, or 5°C and rising, application may commence)
• Dekguard A Plus should not be applied at less than 3°C above the dew point or >85% RH, or in windy conditions, where early-age dust adhesion may occur, where rain is likely within 2 hours at 20°C or 20 hours at 5°C, or where there is a likelihood of exposure to frost within 48 hours of application
• Dekguard A Plus should not be considered for areas subjected to exposure to ponded water. Dekguard S should be considered where occasional ponded water is anticipated
• The manufacture of Dekguard coatings is a batch process and despite close manufacturing tolerances variation may occur between batches. Fosroc recommends using material from one batch only as the finish topcoat
