I have several hairline cracks on my newly skimmed (3 months old) walls and ceilings. What's the BEST way to seal them filler or caulk? Should I make the crack wider with a knife so the substance moulds in well????
If you use caulk then this will be remain flexible and allow flexibility with the general movement of the house. Your house will move constantly, with different materials moving, expanding and contracting at differing rates depending on temperature, humidity etc…
It is likely that the cracks have appeared due to this.
By using caulk this will allow some movement and should hopefully prevent the cracks from appearing due to the same reasons in the future.
If you are painting the surface then you will also need to purchase a caulk that can be painted
Thanks, didn't see your response until now! Yes, I have bought caulk which can be painted on. I have also bought this product as I've got a few hairline cracks (extremely faint) in different directions on my walls! I thought this product would help...?
