Things to Consider Before Buying
We know how thrilled you are to get your hands on one of the well-performing ones for restoring the looks of your exterior wooden structures. But before you make a purchase decision, you need to keep some points in mind. By keeping them in mind, you will have a high chance of ending up with the right one. They are:
Formula
The formula is all that it counts when it comes to performance for these. And the manufacturers are going to use two types of formula. One will be water-based, and the other one is going to be solvent-based. If you were on the lookout for something with a low amount of odor, you should get the water-based one.
On the other hand, if the odor is not that much of a factor for you, you can get either of them. It should be noted that the water-based ones are easier to clean. You would not require any sort of cleaning agents for them. So if you are most likely to apply or coat the wrong surface with these, you should go for the water-based ones.
Drying Time
The drying time is something that you should consider by factoring in your skill first. And the skill that we are mostly referring to is the skill of applying solvent and compounds on wooden surfaces.
The ones that dry up fast are convenient, but you are going to get a low amount of working time with those as they are going to settle exceptionally fast.
So if you are good with your hands and have a good amount of skill in shaping the solvents and compounds on the surface quickly, you should go for the ones that dry up fast. On the other hand, if you are not that skillful in this regard, you should opt for the ones that take about 15-20 minutes to cure.
Shrinking and Cracking
As we have mentioned earlier in our exterior wood filler review section, shrinking and cracking are a few of the problems these putties suffer from the most. And if you happen to get one that does have this kind of problem, the layer you are going to get will not last long.
Well, you would not want the blemishes to resurface again that quickly, would you? For that reason, it is important to opt for the ones that are resistant to cracking and shrinking. Those are going to last for a prolonged amount of time without showing any issues.
Frequently Asked Questions
1. Do all of the fillers accept paint and stain?
Yes, most of the putties should be able to accept paint and stain. However, the capability of accepting them well will vary from one to another. The ones with a good formula can naturally take them, and the looks that you would get would be indistinguishable.
2. Can I mix paint with the putties before applying?
No, you should not mix anything with the formula before applying. If you want to paint and stain the surface, you should wait for the putty to cure and then apply those on the surface.
3. How much time does it take for the fillers to dry?
Actually, it depends on the formula. The ones that will have a good amount of wood hardeners induced into them will take about 15 minutes. Nevertheless, most of them should cure up within 20 to 25 minutes.
4. Can I sand the fillers after drying up?
You should be able to sand the surface after it dries up properly. However, do make sure that the filler is cured and dried up properly before you start sanding.
5. Do all fillers smell weird?
These do tend to have a little amount of funky smell to them. However, if the odor is the main factor for you, you should opt for the ones that utilize water-based formula.
