AD2 is a flexible mineral based adhesive with excellent bond strength on a wide range of substrates whilst still remaining vapour open. Similar to our popular AD1, but with fibres for larger areas or where increase flexibility and cracking resistance is required use with PS1 for best results. Independently tested for vapour diffusion to reassure you that water vapour is not trapped in the fabric of your building.
Some typical substrate types: Masonry backgrounds, magnesium silicate boards, historic or new plasters (lime, cement or gypsum), wood, and wood type boards, terracotta and some ceramic tiles and paints
Coverage: On an even surface at 1mm thick 500grams of AD2 will cover approximately 1m² (16kg will cover approximately 32m ²). Allow more for uneven surfaces or beading.
Use: Stir well before use. Always test for bond strength on your specific substrates prior. Best used in combination with PS1 for optimum bond strength, in particular where the surface is powdery or friable, work the primer in to the affected areas with a brush and test for bond strength after 24 hours.
Ensure that surfaces not to be primed are protected, particularly glass. Wash splashes, tools and brushes with water. Do not store or use in extremes of temperatures (<5 or above 30C). If splashed on the skin wash off immediately with water. Wear the appropriate Personal Protective Equipment; Refer to the Safety Data Sheet before use (see download link below)
The primer can be plastered after 24 hours. Ensure that the plaster is appropriate to the task.
