## Questions & Answers

**Q: Can this be used inside?**
A: Yes.  I think people have applied stains with it.  Be sure to wear appropriate PPE whenever using a sprayer inside.

**Q: Can I use this sprayer for water based sealer for my paver driveway?**
A: Yes, have used it for that a few times. Just clean out when done.

**Q: Can use it to stain wooden fence**
A: I don't know since I use the sprayer for landscaping purposes.  The question might be answered by reading the stain manufacturer's information sheet regarding the use of a paint sprayer - which a completely different piece of equipment than this Solo backpack sprayer which is made to use with disinfectants, fertilizers, herbicides and pesticides .  Also are you going to use water base or oil base stain, a translucent or an opaque stain?  Each has a different application method. Water base stain is usually running and are "wipe" off meaning you apply the stain, allow it to penetrate the wood then wipe off the excess before it dries, opaque stains are more similar to paint in that they sit on the surface of the wood and are usually not wiped off, etc... oil versus water gives you may other differences of application and clean up. I suggest you try googling for best sprayers for staining a fence and see what they recommend. Good Luck.

**Q: hi, does this come complete with a harness?**
A: Yes, this comes with the "backpack like" harness. If you search online for images of "Solo 425", some pictures will show you the harness.

### ⭐⭐⭐⭐⭐ Good buy

Spraying herbicide

### ⭐⭐⭐ Not sure
*by D***Z on 17 August 2024*

I’m a professional gardener. So I purchased one these last year for £86 A year later, for some reason it’s jumped nearly £50’in price. But they’re better quality than the cheap £20-£30 ones I’ve been using over the past years. They only seem to last a year or so before corroding or leaking.? So they’re a good well built quality knapsack. The only problems I had with the last one I bought was that there was a stupid plastic clip that held the piping from the knapsack to the lance. It’s a poor design that caused a small leak. I overcame this by removing it and replacing it with a jubilee clip. Problem Solved for the sake of a few pennies. This one had the same stupid plastic clip that will need to be changed. The only other problem I had with the previous knapsack was the poor design of the clips that held the shoulder straps on at the bottom to the metal stand. They occasionally came off due to the clip design. This new one looks as if it’s even worse. They’ve done away with a locking loop. And replaced it with just a clip that in no way locks on. It just doesn’t feel like it’s meant to be connected to the steel base stand. And that it will be forever falling off. It just feels like they’ve had a good design, messed with it. And actually produced a worse product for and charging us an extra £50 for the hassle. I’ve not used it yet, as it was bought to use selective weedkiller on lawns. But any problems, I’ll update the review
