If your Concrete Wall has developed hairline cracks or small holes, you can and should repair it immediately to avoid the damage growing and causing a weak spot in your security.
Firstly, clean the area around the cracks or small holes using coarse sandpaper. Make sure you remove all dirt and dust from the wall.
Next, you need to soak the area around the small holes or cracks and keep wet for a few hours. Doing this will prevent the dry concrete from absorbing the water from the cement grout once you have applied it.
Mix the cement and water in a metal bucket to form a thick. Smooth grout. You need to stir continuously to prevent any lumps from forming.
Next you need to fill the hairline crack with the cement, using a trowel. You can use the trowel handle tip to pack the grout firmly and fully into the holes. Always press and spread the grout into the crack and over the edges, then smooth the grout down with the flat side of your trowel.
Cover the repaired cracks and holes with large plastic sheet, which you must tape with duct tape.
For 5 days, you need to dampen the repaired cracks or holes with a little water, then cover again. Do this every single day for the 5 days.
You can then apply a silane-based sealant to the repairs and a few cms all around the cracks or holes, to ensure a good, stable seal. Use a synthetic bristle paint brush for this.
Make sure you check your walls regularly for any sign or cracks or holes, then repair immediately to prevent any cracks extending or widening, and holes enlarging.
Security is very important today, and in no way must you allow any cracks or holes to stay unattended, thus giving would-be intruders an easy way into your property.
