APPLICATION
SikaGunite GP can be applied dry spraying process. In the dry shot process, the nozzleman determines the water content of the mix and therefore the quality of the sprayed mortar. A lower water/powder ratio can result in too much dust and a higher water/powder ratio can give a flowing mortar that will slump off the substrate. For applications to vertical surfaces up to 175 mm maybe achievable with overhead repairs up to 150mm depending on water additon. After spraying immediately screed off and trowel.

CURING TREATMENT
Proper curing procedures are important to ensure the durability and quality of the repair. To prevent surface cracking, cure the repair mortar using plastic sheets, wet hession, or curing compounds such as SikaCure.

Colour Accuracy Disclaimer: We have taken care to display the most accurate visuals of our products. However, we are not responsible for the colour accuracy of the device you are viewing our swatches on. These variations arise due to different computer monitors and devices (make, model and technology, as well as resolution, contrast and brightness control settings) in much the same way a scan will differ from an original image and a colour photocopy. Furthermore, coatings can exhibit variation in perceived colour depending on gloss level and application method. If you require a very specific colour match, please make your selection via actual swatches and colour boards available at our showroom.

Product Disclaimer: Ensure you read all product, technical and safety data sheets prior to application as liability falls on the applicator. All products must be applied in accordance with manufacturer’s recommended method.
