A-Joint Polysand Pro powered by ECCO 25kg
The 1-component professional jointing sand for concrete and paver surfaces
A-Joint® Polysand Pro is a specially designed water-permeable jointing sand with weed-inhibiting properties, suitable for very narrow joints and for use in heavy traffic applications.
The jointing sand is characterized by its simple and fast application and is suitable for both professionals and DIY users.
The material remains permanently flexible, making it ideal for unbound constructions on both new and renovated substrates. Thanks to this flexibility, cracks are also prevented after curing.
A-Joint® Polysand Pro is low in dust, does not leave a binder film on the stone surface, and is therefore also suitable for jointing coated and sensitive paving stones.
