Introducing Polyurethane Paints

Are you looking for a quality paint but are unsure when it comes to chemistry? Read our article below to find out just why polyurethane paints make great finishing coats.

So…What Is So Great About Polyurethane Paints?

Firstly, polyurethane paints make ideal topcoats in a protective system. Many polyurethanes offer a very high gloss level and are on the whole extremely colour fast. This means their colour retention is far superior to products such as epoxies. Also, polyurethane paints tend to be much thinner than epoxies. Therefore, PU paint typical coverage rates will be around 12 – 15 m2 per litre. Epoxies however are known as a high build product. They can typically cover 3 – 8m2 per litre.

Polyurethane paints are often used in combination with epoxies as a system. Professional contractors typically use paint systems for street furniture on UK highways. These systems sometimes consist of a 2 pack zinc phosphate primer, a 2 pack epoxy build coat, and a PU topcoat.

Polyurethane paints for floors

Polyurethanes are incredibly tough. However, the main purpose of PU paints is to give the substrate a nice shiny finish. This in turn results in a more water repellent surface. PU paints give an extra layer of protection against water ingress. They also protect against UV damage, meaning the colour retention is increased.

You can also apply PU paints in places such as sport hall floors that require a hard glossy clear finish. Promain often specify polyurethanes on bar tops and table tops. This is as they are chemical and abrasion resistant.

Polyurethane Paints For Floors

Promain regularly specify polyurethane paints on floors due to their high coverage. This ensures they are an economical solution to our clients. Polyurethane floor paint is an urethane floor coating that offers good abrasion resistance and colour retention. So, if you are painting your conservatory floor on a south facing building, your floor will fade far less rapidly than an alkyd or an epoxy.

Due to the thin build nature of PU floor paints, many people use a high build epoxy underneath them beforehand. This helps to even out any undulations, making them perfect as a garage floor paint.

Promain provide a wide range of polyurethane garage floor paint. Polyurethanes are ideal for garage floors as they do not suffer from hot tyre pick up like an alkyd would. Take a look at this article to find out more:

However, the best garage floor paint would be a 2 pack epoxy. Read our articles on garage floor paint to decide what is best for your circumstance:

Polyurethane Paints For Wood

Acrylics are ideal for using on wood as they can expand and contract. However, acrylics such as Bedec MSP or Teknos Woodex Aqua Solid are ideal for painting onto wood as they are elastomeric. This means they last as the timber expands and contracts across the seasons.

Clever chemists have also made acrylic / polyurethane wood paint combinations. The benefit of an acrylic paint that contains polyurethane is that the acrylic will expand, and the polyurethane will make the paint far more durable.

Great polyurethane paints for wood include Rust-Oleum XPE or Bedec Aqua Advanced. If painting indoors, Bedec Aqua Advanced is ideal for internal woodwork. We recommend using it on wooden skirting boards and door frames that often get a bashing from children and vacuum cleaners.

Another great polyurethane wood paint is Tikkurila Everal Aqua. Tikkurila Everal Aqua offers high levels of resistance to UV and is ideal for use internally and externally on wood. This makes it perfect for wooden garden items, door frames and interior wood furniture. This product is tintable to over 13,000 different colours and is available in 3 different gloss levels allowing for maximum choice.
