It is crucial to properly seal cracks between floors and walls to create a waterproof barrier. Water and other liquids can eventually cause irreparable damage to the structure. Before coating with ArmorThane, learn how to make sure that there is a good seal.
Waterproof Barriers require connecting two surfaces
The Barrier Issue
A waterproof barrier must be installed where the porch or deck connects to any other structure, such as a house, patio, fence, or supporting beams. Spraying within floors that connect to walls or steps is also a good idea. Uncoated crevices between the walking surface and walls can trap rainwater or other water. Simple caulking can lead to structural deterioration, including concrete cracking and wood rot.
Sealing the cracks and spraying at least half way up the vertical section is the best option. Different substrates might require different preparations and primers. ArmorThane sprays on concrete, wood, brick, and stone.
Connecting Wall to Concrete
To connect the right angles surfaces, a chamfer molding is possible. This creates two minor seams, rather than one major, and gives the edge a more pleasing aesthetic. The chamfer is used to join the exterior wall and floor. It is then attached using our woven fiberglass ArmorTape. The floor is coated with a primer and polymer coating. This can be applied to the entire vertical wall, or to the seams that are just covering the taped seams. For color and UV protection, a topcoat is available.
If concrete is being coated with another material or the coating rubs against concrete, it is best to cut a quarter inch groove between the concrete and wood. For proper sealing, ArmorThane primer and polymer are applied to the wood.
Connect Siding to Wood
A metal flashing is used to cover cracks in wood decking which butts against siding. Before coating, ArmorTape can be applied to seal the flashing. This tape can also be used to seal cracks between planks of wood. The decking is then spray with ArmorThane primer and polyurethane/polyurea. Finally, topcoat is applied.
A Waterproof Barrier
This will provide years of maintenance-free service with a waterproof barrier. The top and underlying structures are resistant to weathering, foot traffic, and furniture movement.
These drawings are intended to provide guidance for the installation and maintenance of ArmorThane coatings. These details should only be used as a guideline. After evaluating the site conditions, code requirements, and other standards, the applicator should make final decisions about the details. Before applying an ArmorThane coating, please read the operation manual, product technical data sheets and material safety data sheet (MSDS).
