Question:
Can this product be used on walls where there is either rising damp or porous joints between the bricks. or do you have other suggested remedy?
Answer:
For this product, you would mix in with your mortar to make it more water tight (it fills the pores) - so this is normally only for a new project. If it is an existing wall, KEN004 would be a more suitable option.
