Hairline cracks in paint are not typically a major issue or a sign of structural damage but could be as a result of many factors such as a warm and humid climate or an improper paint job. Sometimes fine hairline cracks can occur on paint due to an early application of paint when the curing period of the substrate has not elapsed.

Homeowners living in areas where the humidity is too high often find small fine cracks in the paint since temperature changes and constant fluctuations in humidity levels tend to affect the paint. In this article, we will look at some of the most common causes of hairline cracks in paint and how to solve this problem.
How to Fix Hairline Cracks in PaintThe first step will involve analyzing the extent of the cracks in order to identify the best way to solve the problem. Begin by removing the loose and flaking paint using a scraper or a wire brush then sand the entire area to soften out the edges. Prepare this surface just like you would normally do with a new surface that you are about to paint.Prime the surface before applying paint to improve adhesion.
Apply a fresh coat of paint and wait for it to dry off properly before adding a new layer of paint if necessary. For deeper hairline cracks, you may want to use a filler to fill up the cracks before applying a new layer of paint in the affected area. However, if an extensive area has been affected, you will need to scrape off the paint and then sand the entire area to even out the edges before applying a fresh coat of paint.
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.
Wide cracks, holes, gouged-out or crumbled areas, should be completely filled with spackling compound or patching plaster and sanded smooth before painting. Wider cracks that might expand and break through the paint film are best taped and spackled like drywall joints.
Texture paint will also not work well over peeling paint, wallpaper or dirty walls. Since texture paint usually covers less wall area per gallon than regular paint, it is often sold in five-gallon pails, which can be very heavy.
Directions for any texture paint should be read and followed carefully, but virtually all the paints are messy to use. If there is furniture in a room, it should be completely covered with dropcloths, and floors should be covered and the edges of the dropcloths taped at walls to hold them in place.
Then apply paint. If you are applying two coats, always make sure the first coat has properly dried before applying the second coat. A good paint option is Nippon Paint 3-in-1 Medifresh, which is specially formulated to cover hairline cracks.
If it were my house I'd get painting! Paint is intended to seal hairline cracks of this kind. Depending on your locality you may find that it's feasible to spray a paint finish over stucco, which can be by far the easiest and cheapest way to do it.
I recently used DAP All-Purpose Stucco Patch. It comes in a tube too so you can just attach it to your caulking gun. It needs to be painted over. You need to repair those cracks so water does not get in and DAP will seal it along with a coat of paint. You'll need a plastic spreader to spread the mix.
I am fixing cracks right now for an apartment building. There is nothing I am doing that hasn't been done already. Buy some good decent caulk and run a bead over the crack then smear it into the crack with your finger. It will come back slower or faster depending on how well you ran the bead.
Flaking paint occurs when cracked paint begins peeling off its original substrate. In its early stages, the problem appears as hairline cracks in the paint, but will worsen over time if the problem is not fixed, causing larger pieces of coatings to chip off.
Paint cracking on walls, ceilings, and exterior surfaces happens due to a variety of causes, one of the most common being poor preparation of a surface prior to painting. Painting over cracked paint is a bad idea; it is important to remove any flakes from the surface before repainting.

Never paint over cracked paint.
Allow paint to dry thoroughly before adding another coat.
Hi, need some advice on what to do with fine hairline crack still appearing after painting walls. I've initially filled the crack with compound and all seemed well, I applied a mist coat and a normal coat of paint but now the fine crack has re appeared. Would using mesh tape help hide this crack?
hi there Robert!those cracks are quite annoying ey.(1)-so what i usually do is cover them with mesh tape and apply joint cement, not the ususal polifila as its quite weak and dos not work well with movements; joint cement is lots harder so it holds better. apply thin layers, initially to cove the tape and then to smoth up the edges.
check that you have used a flexible compound when filling due to general movement of the home.Always over fill allow to dry fully before sanding miss coat and repaint wall to remove the repair area.
Hi,chroma response is nearest to solving this one,I'd rake out and pva areas to be filled ,base fill, fiba-tape over cracks,easy fill 20 or 45 minute ,finish using joint cement or lightweight joint cement,lightweight preferable,each coat should be spread out further than the previous coat,this will avoid repairs being noticeable and raised.Then depending on previous application method of paint blend repairs by building paint on repairs,this will take flashing and visibility out of repaired areas,read feedback on Derek 8 July 2014.

Most definitely widen them first, otherwise they will just reappear a few weeks after the paint dries. It's easier than you may imagine: drag one of the sharp corners of a metal scraper along the cracks to form a shallow v shape groove, which will hold a small amount of filler. It doesn't have to be deep & wide, one quick drag will do it An old scraper is fine to use. Putting filler over fine cracks won't work. Like painting over, the fine coating will give you the impression that you succeeded... and then crack again after a short time. Use a medium grade sand paper if you don't want too smooth a finish .I find a soft sanding block is a good option for plaster. You can wash the dust from them.

It's quite normal for small cracks to appear in plaster on interior walls and ceilings, either through drying out in new homes or movement of the building in older homes. Simply enlarge the cracks slightly using a scraper (fillers don't work well in hairline cracks), dust off and fill with a suitable product such as Polycell Trade Interior filler.
