NRC has a better compatible strength with historic masonry and renders due to the special processing of gaultstone and the lower kiln temperatures used. Please note bags are dated with manufacture date. It is known that NRC has a considerably longer shelf life than other cements.

Silic8 Mineral Adhesive AD1

AD1 is a mineral based adhesive with excellent bond strength specially designed for general use remaining highly vapour open. Silic8 adhesives are the only known adhesive on the market to be independently tested for vapour diffusion to reassure you that water vapour is not trapped in the fabric of your building. Our adhesives are also tested as non combustible. 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*.  An in-house testing facility for bond strength is offered if you have specific requirements** Coverage: On an even surface troweled with a toothed trowel 1200g will cover approximately 1m²  Allow more for uneven surfaces. 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 surrounding surfaces 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. The primer can be plastered after 24 hours. Ensure that the plaster is appropriate to the task. * We do not take responsibility for compatibility with any of the suggested or unlisted substrates types. **A charge is made for this service  and is only indicative of actual bond strength. Not all substrates are suitable for testing at our facility. Due to the variation of substrate types we recommend that a representative area of substrate to be primed is first tested to satisfy all your requirements
