Why HP-PP-TEXTUR?
A polyurethane coating can bring its advantages to bear especially under difficult conditions. The surfaces of pools and bathing ponds are ideal for this. HP-PP-TEXTUR is mainly used in stair and floor areas due to its non-slip and textured nature.
Which colours are available?
Over 190 different RAL colours can be mixed and delivered. If the pool is exposed to high levels of sunlight, we advise against using too dark colours, as there may be large differences in temperature above and below the water in the pool or pond. This could lead to strong differences in stress in the laminate and thus to cracks.
How can I apply HP-PP-TEXTUR?
Can I apply a 2K system (resin + hardener) to an existing 1K layer?
It is generally not recommended. 2K coatings are usually much harder than 1K coatings and due to the different properties cracking and chipping can occur. In addition, the solvent contained in 2K lacquer can soften the 1K substrate and following might cause irritation of the surface. With a simple test it can be checked whether the old coating is a 1K or 2K coating: Press a cloth soaked in acetone onto the varnish for at least 1 minute. If the surface remains unchanged, it is a 2K coating. If the paint dissolves or curls after a short time, the substrate is a 1K coating and therefore unsuitable for 2K. Old 1-component coatings must therefore always be removed completely!
Resin and hardener were mixed in the bucket. How long can the system be used?
The so-called pot life is 3 - 5 hours. A very important factor is the ambient temperature. The warmer, the shorter the pot life! After 5 hours at approx. 20°C the mixture reacts and becomes viscous. After that it should not be used anymore!
Why does the colour look uneven or irregular during application?
When mixing, it is important to stir each individual component well beforehand and to mix the entire system well afterwards. After mixing, the mixture should be left to stand for approx. 10 minutes so that any bubbles that may have formed can escape.
Does it make sense to apply the paint as thick as possible?
When applying the paint, ensure that the paint is rolled up evenly and not too thick. If the layer is too thick, the entire varnish cannot react with oxygen and therefore cannot harden. This would result in blistering and an uneven colour image. Later, it can even lead to flaking. Tip: It is better to apply twice thinly than once too thick! It should be noted that the first layer should be tack-free before applying the second layer. The second layer must be applied within 24 hours (at 20°C) before the first layer hardens.
I have used much less than specified. Can I return the paint?
All varnishes are mixed on customer order and therefore unfortunately cannot be taken back. In addition, the specified quantity of approx. 150g/m² should be observed. If the paint is applied too thinly, the quality and durability of the coating will be reduced.
The time window for the subsequent coating was exceeded and the substrate has already hardened. Can I still apply the subsequent coating?
A too late application of HP-PUR-PLUS on the first layer or on the primer can lead to orange peel (a disturbance of the colour flow). Furthermore, a chemical bond between the individual layers is no longer guaranteed. Therefore, it would be necessary to sand the surface again after it has dried through and then rub it with acetone to remove dust or grease.
HP-PP-TEXTUR is too rough for me, how can I remedy this?
In this case, an additional layer of HP-PUR-PLUS on top of the HP-PUR-PLUS-TEXTUR would help. The additional layer covers the particles somewhat and thus "defuses" them. In this way, the properties of the non-slip surface can be largely designed as desired. Please note that a fully hardened layer must be sanded and cleaned with acetone.
The colour of the coating fades within a short time. What can be the reason?
The HP-PUR-PLUS has a very high resistance to chemicals and UV light. In the pool area, incorrect chlorination can cause the colour to fade. For this reason, the chlorine content and pH value should be measured regularly. The optimum value for chlorine is 0.3 - 0.6 mg/l and pH 7.0 -7.6. If these values are maintained, you can enjoy the colour stability of the PU coating for years.
