Porcelain paving has very low absorption so it does not adhere well to sand & cement beds. To help the tile stick you need to use a bridging primer on the underside of the tile. The underside of the paving should be clean, dry and free of any material which may impair adhesion - do not apply to shiny surfaces. Do not use in wet weather and do not use if frost is forecast within 24 hours of application. Suitable for use in temperatures between 3°C and 25°C.

Each tub contains two 10kg bags, 20kg covers approximately 21.5m2 depending on the application method and paving porosity. ProJoint Porcelain Primer should be mixed with 2.8 litres of cold clean water per 10kg bag. Remove the bag from the bucket and add the water to the mixing container. Add the powder slowly and mix using a whisk. Mix for 2 minutes, leave standing for 2 minutes then re-mix - this process allows the polymer additives to dissolve and activate.

You can then apply to the back of the tile using either a brush or a roller. The pot life of the mixed slurry is approximately 60 minutes at 20°C. The primer should be completely dry prior to laying the paving. Depending on temperature and moisture, primer will be dry within 10 to 15 minutes however the paving can be laid up to 24 hours after application.

Remove any primer from the sides or face of the tile immediately - do not let this dry as it can be extremely hard to remove once dried.

At Green Garden Paving we are passionate about porcelain. As UK market leaders in the supply of porcelain paving, we stock a variety of vitrified products suitable for a range of landscaping and architectural projects. We have over sixty years experience in the tile industry, which gives us valuable knowledge and experience in working with porcelain. We believe that porcelain cannot be treated in the same way as traditional paving products, which is why we recommend different installation methods to many of our competitors who specialise in natural stone or concrete paving.

All external porcelain at Green Garden Paving is a minimum of 18mm thick with R11 rated slip resistance. We offer full or cut samples and delivery is free on all orders over £300 (ex VAT). Products are available from stock in our Hampshire warehouse, where you can also view our external porcelain display garden which has been installed using the PorcelQuick Adped system. If you have any questions please do not hesitate to contact one of our friendly team for advice.
