You see a crack in one of your buildings. You know it needs new sealant. You meet with a few building maintenance companies and they give you some estimates. Before you jump on the cheapest offer, you may want to know why there is such a large price disparity. What can initially be a cheap, quick fix could ultimately turn into an expensive headache. Choose the right sealant up front and avoid reoccurring repairs in the future.
Repairing of hairline cracks in plaster
Application- The hairline cracks, are widened, using a sharp tool (e.g. a chisel) or a cutting wheel, to at least 3to 5 mm.
- Dust and other loose particles should be removed from the crack with a brush or by an Air Blower.
- The Crack Filler is cut at an angle and in a way that it cannot penetrate but lies on the edges of the widened crack.
- The sealant is applied by guiding the tube at an angle of 450 along the crack.
- The sealant should be smoothed out with a smooth trowel, while it is still fresh
