Repairing Hairline Cracks and Why They Appear on Window and Door Corners

What's the right concrete repair product for hairline cracks? Why do they usually occur on window and door corners?

Repairing hairline cracks on walls can be tricky as this type of concrete damage can recur or aggravate when repaired using the wrong product and method.

Hairline cracks could occur due to movements and vibrations on the wall, especially on windows and doors. Without a strong frame or support (lintel beams), hairline cracks will gradually form on the weak parts of the wall. Other causes of hairline cracks include: external blunt impacts, concrete deterioration, and poor compressive strength.

Delaying the concrete repair for these cracks can be expensive and, sometimes, dangerous. Plus, you have to choose a product that can restore the aesthetic quality of your wall. So, it should allow repainting.

The process of repairing concrete cracks can be complicated as you need to consider many factors, such as gauging the depth of concrete damage, the right cut to use, and most importantly, the products and methods for repairing such micro-sized cracks.

Suitable method for concrete crack repair can be selected based on evaluation of the crack in structure for its causes. Once the cause is known and type of crack is established, then suitable method can be selected.

If the cracking was primarily due to drying shrinkage, then it is likely that after a period of time the cracks will stabilize. On the other hand, if the cracks are due to a continuing foundation settlement, repair will be of no use until the settlement problem is corrected. As for structural crack repair, the damage has to be diagnosed and addressed immediately to prevent the damage from aggravating.

Fortunately, there's a cheaper and faster solution to repair concrete hairline cracks, which prevents expensive and complicated problems from happening, which can also restore the beauty of your building.

In this video, we’re going to talk about the right product to use in fixing hairline cracks, concrete repair products for such cracks, and concrete repair application and methodology.

SAPAL 2 in 1 is a weather-resistant, water-based acrylic sealant, waterproofing material for sealing gutters, roofs, joints, and hairline cracks. It cures to a tough elastic film that can withstand severe expansion and contraction. It does not crack over time and can be painted over with a water-based paint.

Hello,
First of all thank you for sharing this video in a platform where most of the people are searching for any solution.
I too have such kind of hairline cracks in my apartment's walls. They are not wide but long enough to put anyone in worry.
Question: what could possibly happen if we don't repair these walls with about 1-2mm width hairline crack? Is the wall going to fall after some years? Will the size and shape of existing crack change? Will it become more wider and longer, affecting other walls too?

Hello sir.. If I want to apply sapal 2 in 1 sa hairline cracks and at the same time e waterproof na din, hahaluan po ba ng water? O apply directly lang?

[BoredGeese]
