Stone Cleaning & Sealing
As with any project planning is essential to ensure that the surface to be sealed is fully cleaned and free from organic and bacterial growth, both on the surface and within the stone.
This is why Proshield recommend the Doff Integra to prepare stone before sealing. Doff produces 150c at the tip to ensure all stone is throughly cleaned, whilst it’s ultra low pressure operating capabilities make it the professional stone cleaning contractors preferred method.
After the surface has been cleaned it is essential to allow the substrate time to dry. As Doff produces steam to clean this happens quickly thus allowing sealing of the stone to proceed shortly after. An ideal drying period of 12/24 hours is recommended to ensure the sealer can penetrate the substrate and provide its impregnation sealing capability.
