Restoring old picture frames

I love how much work went into old picture frames. They often told as much of a story as the picture inside. I see lots of frames in my business that have not been treated well, that have been stored badly in sheds or sat in rooms with smoke building up on them for years. It's great to be able to get the frames back to their glory days and let their beauty shine on through. If you are looking to do some restoration of your own, my site has a collection of the tips and tricks I've learnt over the years to get the best effects.

Will You Need Low-Pressure or High-Pressure Injection to Repair the Cracks in Your Walls?

Cracks in your house's walls or foundations need to be repaired as quickly as possible before they get any worse. They are typically dealt with simply by filling the cracks with a substance, usually epoxy or polyurethane. The two main methods that your repairer may use are low-pressure or high-pressure injection. Here is an explanation of each.

Low-pressure injection

Low-pressure injections are probably the more common method of injecting filler into a crack. The repairer will use either a gun or a hand-held spray and will insert the filler into the concrete under very low pressure. The substance will settle into the crack under gravity rather than because the pressure has forced it into place.

Although this method can be a highly effective method of filling a crack in concrete, it is not suitable under all circumstances. Low-pressure injection is most effective for larger cracks, particularly when they are fairly stable and are unlikely to get any larger. If the crack is too narrow, it will not be possible to fill it completely with the sealant. This can lead to water getting into the unfilled area, which can loosen the filler and worsen the crack. Low-pressure injection must also be carried out in completely dry conditions.

High-pressure injection

High-pressure injection is an alternative method that can be used on narrower cracks. Here the filler is injected via special ports that are inserted into the concrete at an angle to the crack. The ports will be near the middle of the crack so that the filler flows out to the narrower ends and fills it entirely.

Care must be taken to keep the pressure at the right level; if it is too low, it will not fill the crack properly, but if it is too high, it can cause small cracks to appear around the larger one. These will divert the course of the filling agent and will again stop the crack from being filled properly. High-pressure injection is therefore a very skilled job that can only be carried out by someone with a lot of experience and training in the technique.

Which method to use will depend upon the size and location of the crack. If you notice any problems with your walls or foundations, you should call in a crack repair professional to inspect the problem. They will be able to choose the correct method to fill the crack and ensure that your home remains safe and in good repair.
