I had my walls reskimmed on Saturday however, I have come across hairline cracks at all of my board joints down one wall, (Every 600mm) it has been revealed to me that when my house was built the joints of board had not been taped on one wall (Found as we can see tape behind skirting on other walls but not on this), thus hair line cracks have appeared. Can i get the joints taped now on the current surface and have the wall skimmed again? If so what is the best tape to used to eliminate hairline cracks?
