COELAN coatings retain their gloss for years. Little if any touch up is required.
Elongation is approximately 335%. This means that COELAN can be stretched three times its length before breaking.
When applied per manufacturer's instructions, COELAN is a very resilient coating and stands up to heavy wear. It is very useful for steps, benches, floorboards etc.
Yes, it bonds very well to these woods. The appropriate primer also affects this. Do not use thinners to remove oil and no other sealers are required. Just do dry sanding with 80-grain sandpaper and vacuum residual dust thoroughly before putting the primer on.
Yes, COELAN bonds to all polyurethane sealers, like Sikkaflex etc. Like many other products it does NOT bond to silicone sealers or silicone based products.
Yes, a matte finish can be applied on top of the last coating. It should be applied thinly otherwise the matte effect will not come out. It is not recommended for decks or floorboards, as it is more slippery than the gloss finish. This is due to the microscopic sized glass particles, which create the overall matte effect.
COELAN is far less slippery than ordinary varnish due to its "rubbery" texture. Like most surfaces when wet, a risk of slipping always exists. There is a very effective anti-slip application possible using COELAN's glass beads along with the optional use of the ANTI-SLIP pre-punched tape.
No, the COELAN coating has a micro porous structure, which allows the transfer of moisture or condensation between the wood and the environment. This unique ability will prevent the properly applied coating from cracking or lifting. Deterioration of the wood is frequently a problem with most paint or varnish as moisture or the effects of UV light will erode the coating or wood.
COELAN coating allows the wood to remain at its natural low moisture equilibrium point. The wood must be dry (max. 15% moisture content) when applying COELAN. Refer to the detailed user guidelines.
The microscopic coating porosity can, in very wet conditions, result in a milky condensation under the top layer of the coating. There is NO damage to the coating. In fact, this is proof of the coating's ability to transfer moisture. In this case, overlying moisture or small pools of water inhibit the transfer. The milky water condensation will disappear. This normal transfer capability is restored due to the combined effects of sun and wind.
A great advantage of the product is WATER-VAPOUR EXCHANGE. This maintains the natural ability of wood to "breath" and exchange moisture. The innovation makes it possible for the natural condensation water to vaporise in a natural process. This protects the wood core from a creeping rotten process. Further, like a valve it provides a way for the condensation to evaporate, and it avoids the tear and peeling of the coating caused by vapour pressure when it is not able to vaporise. The WATER-VAPOUR EXCHANGE of COELAN provides for an application that is good for many years! The typical WATER-VAPOUR EXCHANGE through the coating will be visible by a temporary dimming of the surface or parts of it (spots) at more moistures areas on the surface - an indication for the correct function of the Water-Vapour Exchange system. I.e. this can be seen in the morning after heavy rainfalls, and this milky colour disappears as soon as the sun shines again.
Unopened, COELAN will last for at least 12 months. Opened tins are best used the same day or very shortly thereafter due to the effects of humidity and heat. Some thinning may be required. Careful calculation of product requirements will help you to order appropriate sized containers. It is also a good idea to order several smaller sized tins for future touch up. Every shipment of COELAN Marine Coating Products is given a rigid quality control check prior to leaving the factory.
COELAN, a product of Kemper Systems, is a range of products that have long been appreciated by European boat owners and those in the European shipbuilding community. COELAN Boat Coating is a preferred choice among private boaters and those in the North American marine industry as well. In North America, Kemper System products have been used for many years, particularly in the preservation of such important landmarks as the Empire State Building, the US Capitol in Washington DC, the Massachusetts Institute of Technology, the Philadelphia Art Museum, the Capitol Building in Olympia, the Rockefeller Center in New York City and many others.
In Germany COELAN Industry Products have been on the market for many years. Based on their success, the COELAN Marine Product line has been developed and has been on the market for many years now. COELAN is known in Europe as a top quality product and has proven itself in the Mediterranean where varnishes usually disintegrate in half a year. Articles in recent boating publications have also supported COELAN's quality claims.
Between 5 and 30 °C / 41 and 86 F. Avoid applying COELAN in direct sunlight! Use in constant or descending temperatures. Temperature itself is not the prime concern. Relative air humidity (moisture) is more influential. High humidity = fast drying, (+/- 2 hours), low humidity = slow drying (+/- 6 – 12 hours). Use of COELAN Retardation Agent may be required.
In order to achieve optimum long-term results and ensure maximum product characteristics, the final coating thickness must be 1.0 mm (0.039").
On horizontal surfaces this value is normally reached in 5 very full layers, or 7/8 layers (thinned) on vertical surfaces. COELAN must be thinned by +/- 25% to prevent dripping. Only use the special COELAN THINNER to thin the product for spray applications or for application to vertical surfaces. COELAN can be thinned to work more easily but always apply a rich full coat in order to get the best results. If possible, measure the thickness of the wood prior to coating and then apply 5 layers totalling 1.0 mm thick.
Between 2 – 4 hours in normal humidity conditions. Thereafter the next coat can be applied without sanding. One can work quite fast this way.
No. No sanding is required if the next coat is applied within 14 days. The bonding is then chemical. This saves a lot of work. After 14 days sand with 80-grain sandpaper to achieve good bondage.
Yes, COELAN is a very strong adhesive as well. So take care with putting COELAN coated objects on top of surfaces, because they will glue together. This adhesive effect between two coated objects cures for approx. 14 days until the coating is fully set. So take care not to lay two coated objects against each other. Use wax paper in between if necessary. Use gloves for your hands.
Normally apply COELAN 0.5 centimetre on top of the anti fouling. The waterline can be painted with COELAN or normal strong waterline paint. The product should not be applied below the waterline.
Please see the COELAN User Guide or the detailed Application Instructions. Further Working Tips & Tricks are provided for your assistance.
Use a heat gun to soften the coating and then lift with a wide putty knife. For localized areas, cut out the damaged area including a sufficient boundary, using a sharp utility knife. Re-sand, re-prime and build up several layers of coating to ensure a minimum of 1.0 mm thickness and smooth transition onto adjacent existing coating.
