You need to know that the minimum ambient temperature for applying a coloured concrete sealer is 50 degrees Fahrenheit. This includes both the surface and air temperatures in this case. This temperature range applies to almost all concrete coatings and sealers.
Benefits of using high-speed buffing for finish coats
If you want the best possible gloss and performance from your coloured concrete sealer, you opt for high-speed buffing. You also apply it using a high-speed applicator. These are machines with rotary heads that have a minimum speed of 2000 rpm (revolutions per minute). There is a good reason for this. By using such a machine, you generate more heat that melts the wax-resin in the sealers and thus leads to better cross-linking. This makes the surface film tighter and you get the glossiest surface too.
Basics to know for sealing concrete in hot weather
Most of the one-part sealers, used for protecting and beautifying decorative concrete work, function on a principle named evaporative curing. Here, the liquid part of the sealer evaporates. This leaves behind a layer of solid plastic resin, which forms a transparent and tough film on the surface.
The rate of evaporation in such coloured concrete sealer is directly proportional to the increase in ambient temperature. This happens even more in the case of solvent-based sealers. The ideal temperature range for such work is 50 to 90 degrees Fahrenheit. Also, look at the technical guidelines of the sealer you are using. This is because some of these sealers can evaporate at the rate of knots. Surface temperature is the most important factor in this context, but that does not mean you can rule out the role air temperature plays in such a work. In these cases, it is always better to avoid sealing work during the daytime in the summer months as it is too hot. This can lead to issues like bubbles and spider webbing.
What are tinted sealers?
The tinted sealers provide you all the benefits you get from a coloured concrete sealer, but with a low dose of colour. You can get tinted sealers in both water-based and solvent-based products. However, your choice in this context depends on the result you are looking to get from such a product. You get pre-tinted sealers from some companies. In other cases, they offer you tint concentrates in a diverse range of colours. You can add these to your coloured sealer at the project site. They are metal-based pigments in the water and are finely dispersed in nature.
How to select the right sealer?
When you are selecting a coloured concrete sealer, you need to focus on certain aspects such as safety, performance, and appearance. Ensure that your sealers are slip-resistant and do not emit harmful fumes when you apply them. Sealers are available in various levels of sheen ranging from glossy to satin. The glossier it is, the richer is the colour you get from the same. The most important performance-related criteria in this context are thickness, weather resistance, durability, and maintenance requirements.
