INSTRUCTIONS FOR HANDLING CRACK EXTERNAL WALL 

Outdoor wall cracking has been a very common practice today. And to handle cracked walls through Youtube, you must have seen that there are many ways for you to handle cracked walls. However, to talk about the easiest way to do it, the way to do it like in the video will be the best for you.

With the solution in this video, to handle cracks for outdoor walls, you first need to prepare materials for construction.

Supplies for disposal will include:

• Crack sealer. As shown in the Video is Sika flexconstruction AP glue. This is a form of Polyurethane glue with elasticity and very good adhesion to the wall.

• Outdoor wall waterproofing membrane. In the Video is using Sika raintite outdoor waterproof membrane. You can also use equivalent products. Please choose acrylic-based waterproofing materials with good elasticity and UV resistance.

The order of execution:

• First you need to identify the crack in the wall. Then you cut and widen the V-shaped crack. After cutting the crack, you need to clean it. Cleaning the surface of the crack before applying the glue will help the sealant adhere better to the wall.

Cut and widen the crack

• After cleaning the surface, you will proceed to seal the glue into the cracks. You will seal sika flexconstruction into the crack filling the volume you cut out. After filling, you will use a putty table to flatten the glue. Note that the surface before filling needs to be clean, and dry. If the surface is dirty and damp, the glue will not stick.

Apply glue to the crack

• The next step is that you will cover the waterproofing membrane on the crack that you cut out. You use waterproof membrane Sika raintite or sika coatplus to cover the crack surface. You will apply 2 layers of sika raintite waterproofing membrane on the wall in the shape of a cross.

Cover the crack with a waterproof membrane
