Sheetrock® Brand Durabond® Setting-Type Joint Compounds and Sheetrock® Brand Easy Sand™ Lightweight Setting-Type Joint Compounds are the best products to use for repairing cracks. If you want to use a ready-mixed joint compound, Sheetrock® Brand All Purpose Joint Compound works well.
If the crack appears on a flat surface, use spackle or joint compound, available pre-mixed from the local hardware store. Spackle and joint compound can also be use for cracks along a wall edge or an outside corner. It will hold and dry even at odd angles. Use caulk if cracks appear where the ceiling meets the wall.
Erase-A-Hole The Original Drywall Repair Putty
It's a soft putty that comes in a compact applicator to quickly work the product into small holes and cracks. It works great on drywall, plaster, and wood—though we wouldn't suggest using it on anything bigger than a . 5-inch hole.
Hairline cracks under 1/2 inch long can often be patched with a thin layer of drywall spackling compound. Use a small putty knife to spread the compound evenly over the crack until it's flush with the surrounding wall.
However, a plaster filler like Polyfilla or a powder filler are probably the best options for filling plaster cracks, as alternatives such as caulk are best used for other purposes, like sealing gaps around pipes or tiles.
Latex paint will hide hairline cracks in plaster, at least temporarily. The coverup, though, may last only a few hours or a few months. Small plaster cracks have an annoying way of showing up again and again. It may be smarter to enlarge them and fix them properly once and for all.
If you have to paint a wall presenting a crack, a solution would be to apply an elastic and over-paintable material inside the crack. Then, apply the paint. Since paints are very thin layers, the material will follow the movements of the crack and will not highlight the problem.
Sometimes known as acrylic latex caulk, this type is best for use with drywall, wood and masonry. It's often called "painter's caulk." This caulk is inexpensive, easy to use, seals well without odors and cleans up easily with water.

The fillers are generally used to fill gaps and holes in walls and wood (often decayed wood). Putty is used to smooth relatively small uneven surfaces caused by screw holes, scratches or coarse materials. The DIY tasks can be very specific.
If you only have a few small holes to fill to get the perfect finish, there is no need to go through the hassle of plastering. Some ready-to-use wall fillers can fill 75mm deep and 50 mm wide holes in one application. But products like Ronseal Big Hole Filler can reach even further for large holes.

Diagonal cracks across the upper parts of the wall (hairline cracks) are usually an indication of a house settling in. Old houses can shift and move over time as temperatures fluctuate. This can result in small cracks appearing as the building adjusts to these minor changes.
