If you’re about to lay down epoxy flooring or install new windows, it is possible you are questioning if you really need to prime the area first. Many individuals and contractors wish they could avoid this part because it adds on an extra day of work, as well as additional costs for the primer — but you really shouldn’t avoid this important step. This is because priming the area first can result in a whole range of benefits. Here are six reasons why you should always use an adhesive bonding primer.

One of the main reasons why people prime their floors and windows is because it helps to reduce the chance of trapped bubbles below the floor. This is especially important if you have concrete below your flooring, as this can generate gas bubbles that create pinhole bubbles in your coating. However, if you properly prime and seal the substrate first, you vastly reduce the chance of gas being released, so you are less likely to wake up to a rippled floor in the future!
Of course, it is important to note there are a few other things that can cause bubbles, so priming it won’t eliminate this risk completely, but it will significantly lower the chance of bubbling happening.
Another benefit of priming your floors and windows is that it improves overall adhesion, as the primer penetrates the substrate, helping to increase the bonding between the two. This will ensure your flooring and windows are durable, helping them to last for decades. It can also assist in reducing the chance of the floor chipping or breaking!
If this is a new home (or the first time you are laying flooring down), priming the floor first will teach you a lot about your floor. This is very useful in older homes. If you are working with older substrates, you may find the floor has absorbed chemicals, including paints, oils, greases and moisture. By applying a small amount of primer to one section of the floor, you will see how the substrate reacts to epoxy, and this will make it easier for you to take precautionary measures to protect the floor.
It is essential to clean your floors before laying down new flooring, and priming is one way to make sure you did the job properly. After all, even if you clean for hours, it is likely there will still be tiny amounts of micro dust on the surface of the floor, which you can’t see. However, priming will effectively remove this dust, creating a fully sealed surface that is ready for new flooring.
Sometimes the substrate can be very dusty, especially if you live in an older home. This can make it more absorbent, which can ruin your new floor; if you try to apply a coating, you may find you end up with an ugly matte look. This is because the absorbent substrate will take all the fluid from the coating, but a primer will stop this from happening. The primer will seal off the absorbent surface, so you can easily apply a paint or varnish coat, without it being partially absorbed.
The final reason to use primers is that they are better than ever before. Developing technology means primers are more effective, helping to create dependable, durable, long-term flooring that can last for decades without becoming damaged. You can also buy specific primers for different jobs; for instance, it is possible to buy primers that are specifically designed for older floors.
Advancements have also made primer easier to work with; now it is simple to apply to your flooring. This means you don’t have to worry about doing something wrong while you apply the primer!
Polyurethane glue, or foaming glue as it is commonly known, has become very popular in joinery and construction applications. Brands such as Gorilla glue have also helped to create an awareness of this type of adhesive in the DIY and retail sector, as it is seen as a ‘stick anything’ product.
In this ultimate guide to polyurethane glue, we are going to discuss:
From the 24th of August , it is mandatory for professional users of polyurethane adhesives and sealants to receive training and certification before using these products in industrial and professional applications.
The most popular types of polyurethane adhesivesare:
Single component, foaming adhesives do not require any resins or hardeners to be added to them. They work by themselves
straight out of the bottle or cartridge. This type of PU glue cures by absorbing moisture from the air and material to be bonded, causing a foaming of the glue during the process.

Single component foaming PU glue is available in two formats:
Single component, polyurethane adhesives are what we will be focusing on in this blog.
Two-part PU adhesives work by mixing two separate components together, Typically:
Two-part polyurethane adhesives are often used in wood flooring applications but are also popular when bonding non-porous materials such as plastics, metals, and composites as they do not rely on moisture to cure.
Although polyurethane based, these formulations have an appearance and viscosity, similar to silicone sealants and hybrid polymers. They are usually dispensed from foil packs and cartridges using a sealant mastic gun and are used extensively in construction trades for sealing expansion joints, and in the caravan industry for bonding and sealing applications.
For this ultimate guide to polyurethane glue, we have listed the advantages, disadvantages, and applications it is best suited to.

In the world of adhesives, polymer technology is always improving, and that ongoing development allows manufacturers to design new products and alternatives which give even stronger bonds and are safer to use.

Wood Max Express is a revolutionary adhesive based on SMP polymers. I must stress, it is important not to confuse this formulation with hybrid polymers such as Sumogrip, CT1 and EB25 which are high strength grab adhesives. Hybrid polymer-based grab adhesives are used for ‘attaching’ one product to another, such as when fixing skirtings and trim.
The incredible bonding power of Wood Max Express is approximately 4x greater than the strongest grab adhesive and effectively joins two pieces of wood to form a single, solid timber component. It can also be used to bond wood to metals, masonry, and other building materials.
Below is a list of advantages of Wood Max Express vs Polyurethane Glue.

Single part foaming polyurethanes are versatile and durable adhesives, offering fast bonding with high strength. They are easy to apply and can give excellent results providing clamping and substrate compatibility are considered.
Fans of PU glue can also be its biggest critic, especially when it comes to cleaning up. That is when revolutionary products like Wood Max Express can fill the void – literally!
