Is your Natural Stone Sealer an Impregnator?
Yes, our high quality sealers for natural stone are classed as 'impregnators' rather than topical sealers. They are specially formulated so that they fill all the microscopic voids in the top layers of a substrate and are very effective at providing long-term protection.

Will the block paving stop weeds from growing?
The block paving sealer will help to prevent weed growth by hardening the soft sand in the joints of the paving. A weed can grow in the smallest of cracks so there is no guarantee that you will not see the odd weed now and again. The block paving sealer will simply help to make ongoing maintenance much easier by inhibiting the growth of weeds.

What type of sand is swept between the joints in block paving?
The best type of sand to use is 'kiln dried' sand that can be purchased from most DIY stores.

My PIC driveway is quite slippery, will this get worse if I apply the imprinted concrete sealer?
The sealer will make the driveway a bit more slipper after application, especially the gloss sealer. If you have concerns about the surface becoming slippery, please use our anti-slip additive with the sealer.

What are the coverage ratios of the sealers?
Coverage ratios will vary between products and are also affected by surface porosity. Please refer to the application guides next to each product that can be downloaded directly from our website.
