I have seen some contractor using some sort of membrane to patch up cracks, was told this will prevent future occurrence.
Vertical cracks on wall, are they normal?

QUOTE(tmchong @ Nov 18 2013, 04:05 PM) Stick the membrane over the crack line? Yes, paste the membrane over the cracks then put plaster over it. Perhaps can Google for more information. Theoretically, it should be something flexible but it is a matter of appearance. If you can't hide it, show it.  |

QUOTE(N73 @ Nov 18 2013, 04:13 PM) My house having the same problem too. I'm more interested what sort of membrane the contractor using. Although, some of the foumer said the acrylic sealant can solve the crack problem but the patch surface will remain soft (not harden forever) and if using the mesh & replastering method will be very costly. Some will seal it with wall putty but cracks will appear overtime. I saw contractor remove the layer of paint, paste membrane covering crack line then plaster/putty over it, let it set, remove uneven surface by sanding and finish it up with a coat of new paint.I'm sure acrylic sealant works the same way. Google for more info. |

QUOTE(N73 @ Nov 19 2013, 11:50 PM) I think what you mentioned is similar to using mesh & re-plastering method. This method will be very costly if there're many crack line. Can give acrylic joint sealant a try first. Don't think can easily get those thin membrane in Malaysia. |
