In my experience, I have seen most cracks go away after using one of the three methods outlined above and never returning. This is because the heat expanded the stucco, sealing up the crack and is a visual indicator that there is movement happening (expansion and contraction). If you go out in the morning on a hot day and look at a stucco wall that has cracks in it and come back later that day, you might notice that there are fewer cracks than there was before. After a crack forms, there will be constant movement in those areas. I have outlined the three main methods to tackling cracking issues in your stucco and I wanted to add what to expect afterwards.
What To Expect From Stucco Crack Repair. This would be the super premium option though and would cost the most. You could even apply mesh on the entire wall, embed a thin base coat and then recoat the wall or walls to better your chances of eliminating any more cracks from forming in the future and getting rid of the existing ones all in one shot. Of course, this is the most labor intense method and will require a lot more materials as well so it will be the most expensive option in most cases but will have the best results overall. You may have to address the cracks before spreading the wall, using mesh over the cracks, embedding a thin base coat and then recoating the wall(s) if you want to have the best chances of eliminating the existing cracks. Recoating The Wall(s): Recoating walls that have cracks in them is the best possible way to make the finish and color match nearly identical while keeping most of the cracks from reappearing. Painting or applying a recoat to the wall(s) afterwards is recommended after these types of repairs to blend them in better. The other aspect of this method that is hard to get right is the color match of the existing finish. The downsides are that blending in the finish can be extremely difficult and the crack areas may be visible afterwards due to the slight difference in texture. Meshing & Blending The Cracks: Meshing the cracks and adding a little more base coat material or mesh, a light base coat and then a finish coat usually stops the cracks from reappearing again because you are reinforcing that area and adding more material. This is just one of those gambles you are taking going this route. Some cracks I have done have lasted 10 years or more and blended great while others have reappeared in a years time.
The downsides to caulking the cracks is usually longevity. You will usually have to paint the wall afterwards for the best results. The cracks can also blend in pretty well if done correctly with the right caulking and the right techniques. I touched briefly on how cost could be affected by each of the three crack repair methods but now I want to dive into some of the advantages and disadvantages of some of the methods.Ĭaulking The Cracks: Caulking the cracks in stucco is obviously going to be the cheapest route to go as far as crack repair goes especially if you do it yourself, which I have a tutorial for here.
