Neutral cure silicone must be used when working with marble, limestone, travertine and all other acid sensitive stone materials. It is a non staining | non etching silicone to fill expansion joints. Mapesil LM & Ardex ST are two premium product brands we carry which absolutely assures you that there is no danger of migration of softeners or other components that could bleed into the edge of the stone unless dealing with ultra porous substrates.
It is important that all horizontal joints meeting vertical ones to be caulked with a neutral cure silicone that will form a flexible waterproof sealant around these joints and will keep surfaces water tight for many years...
Our neutral cure silicone range is truly easy to apply and has good tooling properties. It contains emollients that provides superior adherence to the substrate providing unparalleled protection. Our range contains fungicides built in to resist mold growth.
However re-caulking all joints in wet areas are encouraged every 18 - 24 months. This is also how long the fungicides in this neutral cure silicone can last. Once the fungicide expires, it will give rise to the growth of mold. Regular cleaning and airing out the areas will help extend the lifespan of these expansion joints.
Both Mapei LM & Ardex ST neutral cure silicone will remain elastic after curing. It does not shrink and keeps its colour and is waterproof. It is resistant to most chemicals and solvents and at the same time it is non – toxic after curing. It adheres to glass and most building materials.
Our acid sensitive surface silicone can be used on all natural stone types including that of granite and for all engineered stone and is designed for professional use by tilers and caulkers.
We have seen extreme damages caused by tradesmen when using the wrong silicone type which are usually acetic acid cured. These types of silicone will etch marble and calcium containing materials and may then be subject to specialised restoration cost. This is a terrible shame and we hope by constantly educating the market, we can get everyone to understand why specialised neutral cure silicone products are necessary when working with sensitive natural stone materials.
Our neutral cure silicone comes in 310ml cartridges that have multiple different colours to choose from including that of white, silver grey, cement grey, anthracite, black, jasmine, beige 2000 from Mapei. Alabaster, charred ash, clear, misty grey, sand beige, slate grey, travertine and ultra white from Ardex.
