Whether you are sealing marble worktops, granite countertops or natural stone splashbacks, it is important you choose a non-staining sealant when applying on natural stone surfaces. Most silicones contains silicone oil, which can penetrate into porous stone and result in staining. Once stained, it cannot be removed or reversed.
Hybrid polymers, such as Soudaseal 212 CS, and Neutral Sealant, Silirub MA have been specially formulated for use on natural stone surfaces. This means you can seal joints around marble, granite and other natural stones without any problems.
When applying sealants on natural stone surfaces it is important to select the right product for the job. Soudaseal 212 CS and Silirub MA is independently tested to ensure no staining when applied on natural stone and marble surfaces. Combined with its highly flexible and durable sealing properties, it is the ultimate natural stone sealant.
First, clean the surfaces to remove all dust, dirt and grease. Allow drying thoroughly before proceeding.
To achieve a straight sealant edge, use masking tape to neatly tape off the area. Make sure that the sealant joint is between 5mm and 10mm wide.
Cut the tip off the cartridge with a safety cutter. Screw the nozzle on top and cut the end to suit the size of the joint you would like to fill/seal. Put the cartridge in the caulking gun and squeeze the handle until sealant appears.
TIP: For best results cut the nozzle at an angle.
Place the nozzle where you want to start sealing. Squeeze the handle and move the caulking gun over the joint in a smooth movement. Apply sufficient sealant to ensure that the product adheres well.
Wet your finger in a soap solution or Soudal Joint Finish. Smooth the joint and immediately remove the masking tape. Once removed, carefully smooth away any protruding edges.
Use a plant sprayer with clean water to remove soap residues. This prevents soap stains on the natural stone.
