Pro-Seal 770 Concentrate is a Premium Concrete Binder

This product is a 100% UV stable finder and sealant. It is an integral component of the Water Base sealers sealing system. The Pro-Seal 770 is designed for use prior to application of Pro-Seal 896 or Pro-Seal 898. It is made for use with very porous surfaces and for surfaces where an oxide colour cementitious substrate or surface is being sealed.

Pro-Seal 770 can be used as a binder for grouting and is a great product to use to fill pinholes, surface cracks and flaws in polished concrete applications.

The product is only used as an undercoat and is designed for use on a surface that will withstand traffic such as a driveway or pathway. It is not a stand-alone product. Either Pro-Seal 896 or Pro-Seal 898 must be applied for the final coat.

4 litres of the product seals up to 100m2 of surface. 19 litres seals up to 45m2.

The amount covers dependent upon the surface porosity. If the surface is quite porous it will have more holes or gaps and therefore will require more product.

Pro-Seal 770 limestone sealer is especially formulated as a sealant for sealing applications with a medium to high porosity, making it an ideal sealant for limestone. The polymer gets deep into the material and creates a tough but adaptable substance, providing strength and stability when it is installed over soft materials. Pro-Seal 770 protects soft materials such as limestone from erosion and the elements.

Pro-Seal 770 is great to stabilise the colour of your materials. It enhances and prolongs the colour fastness of coloured concrete materials. Pro-Seal 770 is compatible with cement and cement based products. When used as a mix for toppings and screeds it adds strength and durability and also enhances the colour of your surface – so it looks great for longer.

Pro-Seal 770 has excellent connecting capacities. It fills large pores in highly porous materials which means that the top coats of the product do not soak too deeply into your materials. It remains close to the surface of your material – where it is needed most. Using Pro-Seal 770 as a pre-sealer gives you better coverage and will lower your overall sealing cost. It saves you money on your project.

Pro-Seal 770 is less stain and wear resistant as Pro-Seal 896 and Pro-Seal 898. It is designed for use a stand alone sealer in areas that have low traffic. Pro-Seal 770 is ideal for sealing feature limestone, garden features and retaining walls. However, high traffic environments benefit from an extra layer of protection. For best results apply a final seal coat of Pro-Seal 896 or alternatively use Pro-Seal 898 for added shine.

Pro-Seal 770 is an excellent grouting binder for use in polished concrete floors. It binds the fine grinding dust to fill empty spaces and small pores when it is used in the polishing process.
