Nonetheless, it’s widely advised that you avoid getting the material on your skin in the first place by wearing suitable protective equipment and clothing. In the usual case, the recommended setup is safety goggles, work gloves and clothes that cover all of your skin.

The Characteristics Of Great Stuff

Great Stuff sealant is a type of polyurethane foam that could expand to fill the shapes of gaps and cracks. Seals that utilize Great Stuff foam are completely airtight and water resistant so they are invulnerable to moisture, allergens, insects,…Because the foam adhere very well to wood, plastic, metal, masonry and other common surfaces, it could be used on a variety of sealing project.

For most of the time, Great Stuff foam would usually become rigid and tack-free within 5 – 10 minutes after being sprayed. After 8 hours, you could start scraping away the excess foam and that should be everything. Thanks to the foam color, it’s quite easy for you to detect its presence. The elasticity of the Great Stuff foam allows it to cope with a certain degree of movement and shifting within the structure without becoming undone.

How To Remove Great Stuff

Prolonged skin contact with Great Stuff foam could lead to issues like irritation, allergic reaction and probably even respiratory sensitization. Seek medical assistance right away if there are severed body reactions to the polyurethane foam.  

When The Foam Is Wet

After being sprayed, the foam should stay wet for a few minutes and this is considered to be the best time to remove the material. If Great Stuff foam gets to your skin, you have to promptly grab a piece of cloth and use it to wipe the sealant off.  Pay utmost attention while you wipe the cloth, you definitely don’t want to spread the foam further by accident.

  • Great Stuff shall expand to fill the hollow space, therefore, you should only fill the gaps and cracks up to 50%. Overfilling would cause the Great Stuff polyurethane foam to expand too much and damage the structural integrity in the process.

How Many Amps Does A Dryer Use: A Comprehensive Analysis

Nowadays, almost every family around the globe possesses a hair dryer in their house, it’s a popular household appliance. However, people only care about the drying performance of the dryer and pay very little attention to its electric current along with energy rating. Do you know how many amps does a dryer use? In the case the issue never crosses your mind, this article could provide with the answer and some interesting information.

How Many Amps Does A Dryer Use

In most of the case, you should be able to find the rating of the dryer electric current on the information label of the appliance. Otherwise, you may have to do some conversions. Old dryers often use 15 – 20 amps but modern products could go as high as 30 amps. Generally speaking, hair dryers are surprisingly powerful and energy-hungry for their sizes. Therefore, it’s very unwise to underestimate the hair dryer influence on the house electrical system.

Before you buy a fryer, you must ensure that its handling characteristics and electric ratings are suitable for your house. It’s not exactly an expensive investment that requires thorough inspection but to buy an electric appliance without proper consideration is strongly ill-advised nonetheless. Beside the fact the dryer may be unable to satisfy your need, you would risk the integrity of the house wiring arrangement if you buy on a whim.

The Consequences Of Underestimating The Dyer Impact On The System

So you are in rush to get ready for work, you grab your dryer, plug it in and without warning, you are surrounded by darkness. There are many things that could cause power overload but if they often happen when you drying your hair, your dryer may be the culprit. In order to get rid of the constant outages or at least alleviate the situation somewhat, you could try out these methods below:

Check Out The Circuit Breaker

The circuit breaker job is to monitor the flow of electricity on a circuit and disconnects power when the current reach above the determined level. In order to avoid overheating and prevent electrical fire, it’s important not to choose a circuit breaker with a high rating. On the other hand, a breaker with a low rating is also inappropriate since it’s going to “trip” continuously which shall prove very frustrating for most people.

For example, if your dyer rating is 30 amps but your breaker is rated at 20 amps, the breaker would trip every time you use the dryer. In contrast, if you use a 40 amps breaker on a circuit that is designed to carry 30 amps, the current would be allowed to pass through undisturbed till it exceeds 40 amps. This is extremely dangerous since by the time the breaker could do its job, the entire system may overheat already.

Reduce The Number Of Appliances

One of the simplest ways to solve power outages caused by circuit overload is to reduce the number of appliances in use on one circuit. For instance, in the summer/winter, people often use many devices to keep the house temperature at an acceptable level. Leaving multiple appliances on at the same time may generate a load that exceeds the capacity of the electrical wiring.

For the solution, it’s recommended that you disperse all plugged in device across the house circuits. You could use extension so you don’t have to concentrate many appliances on a particular circuit. In order to figure out the number of the circuits you have in the house, you should check out the breaker box. If needed, you could call an electrician over and let him take a look at the breaker box as well as the house electrical system.

Increase The Circuit Power Rating

Homes that are built before the end of the 20th century often have circuits with a rather low power rating compared to modern day appliances. As a result, it could be difficult for you to use hair dryers with high power ratings in such houses. While it’s easy to buy a hair dryer that matches the power rating of the house circuits, you should consider updating the house wiring.

By getting new internal wiring, you would be able to increase the circuit power rating as well as solve a wide range of electrical problems. It’s always good to know that the electrical system of your house is safe, modern and up to date. Technically speaking, you could attempt to do the wiring on your own as long as you have the tools and know exactly what to do. If you need help, there are a lot of places that offer rewiring and maintenance service.

Give Your Dryer Its Own Circuit

If the above methods appear to be ineffective of not feasible to you, you could give your dryer its personal circuit with a proper rating. That should solve your overload issue or significantly reduce the number of times it happens.

The unit integrity, gauge, pressure and others would be examined before it could be refilled. Immediate refill is similar though it occurs after you use the unit no matter how much fire suppression agents are used.  

The fire extinguisher refill process

At first, the unit condition and its pressure will be evaluated in order to determine the best course of action. For example, units that have a slightly low pressure will be refilled with a sufficient amount of fire suppression agent. On the other hand, units with an unacceptably low pressure will be emptied and cleaned before being refilled with agents. After the refilling is finished, all units should have a pressure between 185 and 205 psi.

To ensure consistent performance and prevent leakage, parts that appear to be damaged or deteriorated would be replaced without delay. The last thing people want to experience is to see their fire extinguisher fail unexpectedly while they are dealing with a fire. For aged units, a hydrostatic test is necessary to check whether the strength of the fire extinguisher remain adequate for people to use or not.  

How to tell if your unit needs a refill

You only need to take a look at the fire extinguisher gauge in order to figure out whether it needs to be refilled or not. Almost all fire extinguishers in circulation come with an easy to understand gauge which consists of a green zone and a red zone.

How To Join Two Pieces Of Wood At 90 degrees: A Beginner Guide

Making wood joints is considered to be the most basic technique that all woodworker, amateur and professional, have to know by heart. Different projects may come with different requirements which means it’s wise for you to learn more than one way to fabricate wood joints. In the case you want to know more about how to join two pieces of wood at 90 degrees, you come to the right places.

An Overview Of The Joints


For most of the time, wood joints are primarily used when you want to attach two wood pieces together and assemble a more complex structure. Popular joint types are relatively simple to make using woodworking fasteners but there are other designs that require precise cutting. Some advanced forms of wood joints are even capable of holding pieces of wood together with nothing more than friction.

So what kind of wood joint should you use for your woodworking project? Well, to answer this question, you have to take a good look at the requirement of the project as well as your own taste. In most of the case, there are 5 factors you should consider: Fitness, Strength, Flexibility, Appearance and Ease Of Construction. By establishing the conditions of the joint, you should be able to figure out what type to use.

Types Of Right Angle Joints

In this part, we will talk about commonly used wood joints along with their characteristics and how to make them. While making wood joints is not exactly a demanding task, you still have to take care of yourself. Wear proper clothing and put on protective accessories just to be on the safe side. If your tools seem kind of dull, don’t take chance and sharpen them first. Inspect the pieces carefully so you don’t miss leftover nail, screw, etc.

Butt Joint

In term of simplicity, nothing can beat the butt joint, it’s essentially one of the most straightforward designs in existence. If you want to make a right angle joint within the shortest amount of time possible, you definitely need to consider using this joint. All you have to do to is to join pieces of wood at their respective ends with the help of screw, nail and alike.

However, due to the potential difference in grain and exposure, you should reinforce a butt joint in any way possible. Usually, adhesives are not going to cut it so it’s recommended that you go after nails and screws. Countersink and putty are necessary to keep the nails/screws from getting loose as time goes by.

Dovetail Joint

Well appreciated for its strength and aesthetic value, the dovetail joint is a really good choice if you are sufficiently skilled at woodworking. It involves cutting a series of “pins” and “tails” on two different piece of wood before finally joining them together. After that, you only have to secure the wood pieces with adhesive, there is no need to use fasteners here.

As it possesses excellent tensile strength, people often use dovetail joints to combine parts of wooden furniture such as cabinets. Generally speaking, tight-fitting dovetail joints should last for a long time but there is no need to worry if you are unable to make a perfect joint. Due to the design, even a sloppy dovetail joint could be strong and long lasting as well.

Mortise and Tenon Joint

Mortise and tenon joint is a balanced design that proves to be strong and simple. You could use the joint to attach wood pieces end to end but it also works quite well in intersected setups. To make the joint, you have to prepare a mortise hole and a tenon tongue, both of them are rectangular. From the outside, mortise and tenon joints appear to be similar to butt joints but they actually utilize a different way to secure the connection between the pieces.

After you finished shaping the pieces, the only thing left to do is to fit the tenon tongue into the mortise hole. To lock everything in place, adhesives are the most common choice though there are certain variants of Mortise and tenon joint that employ pins or wedge.
