On non-porous surfaces like corrugated metal roofs, BULLDOGSEAL can be applied as a one step system – normally by means of a brush. On porous surfaces; for example concrete, it is advisable to pre-dilute some BULLDOGSEAL with an equal amount of water and apply as a primer, followed by undiluted BULLDOGSEAL.

As BULLDOGSEAL exhibits bridging properties, it may also be used in non-waterproofing applications such as cracks in wall surfaces, porous building blocks, wooden fascias and the reparation of spalled areas.
