OnecomponentSikaflex ® Polyurethaneproducts exhibit excellent adhesiveproperties and a high degreeof mechanical strength once thecuring process is concluded.The chemical reaction of onecomponentSikaflex ® Polyurethaneproducts require some precautionsas far as the handling and the curingtime is concerned.Handling TimeHandling time and time to full loadare determined not only by thestresses involved, but also by theaccess of moisture, as Sikaflex ®products cure by way of moisturediffusion from the outside inwardinto the adhesive bead. The speed ofcure and strength development canbe significantly influenced by thedesign of the joint, the porosity ofthe substrate(s), the absolute humidityin the air, the ambient temperatureand the temperature ofthe substrate.The handling and curing time willvary with each type of applicationon board and the loads involved.Open TimeThe open time is the time the adhesivecan be left before the skinningof the adhesive starts to interferewith the adhesion; the open time,depending on the kind of adhesivechosen and the climatic conditions,can typically vary from 15 minutesto 60 minutes.Cure TimeThe cure time is considered the timespan required for the adhesive tocure until full load can be applied tothe finished part.Good joint design ensures unrestrictedaccess of humidity aroundthe joint and is important for optimizingproduction times.

Prior to that,however, excess cured Sikaflex ® -290 DC should be removed with asharp chisel or knife. This procedurewill avoid excess pull on theedges of the seams during the subsequentsanding operation. Foreffective sanding results use an industrialsander. It is recommendedto begin with a medium (80)progressing to a 120 grit or finer.Suitable sanders are beltsanders,flat plate sanders or elastically suspendedsanders. Sanding should bealong the direction of the seams.The Finishing TouchAlthough we do not recommend theapplication of a finish to the exteriorteak deck, many boat ownersprefer to apply a lacquer finish tothe deck after sanding. Generallygreat care should be taken as finishescontain solvents or plasticizerswhich can adversely affect the curedSikaflex ® -290 DC or the drying ofthe lacquer. The following criteriaNever apply the lacquer finish touncured Sikaflex ® -290 DC. Waitingtime of at least one month beforeapplication of the finish is recommended.The compatibility of the lacquershould be evaluated on a smallsample area of the teak deck beforeapplication.Rigid lacquers have a negativeeffect on the elasticity of thejoint and might cause loss of adhesionof the Sikaflex ® -290 DC fromthe teak planks.The MaintenanceIt is important to wet and rinse thedeck regularly with fresh water inorder to prevent drying out. Inwarm climates this procedureshould be carried out on a daily basis.The occasional use of a mild detergent(natural liquid soap) dilutedin water should be kept to a min-AppendixPrefabricated teak decks oftenconsist of a multilayer construction,e.g. they are made of wood ontowhich a fine layer of teak is bonded.The base wood might consist of variouswood qualities; the pores inthe “wood” are different in structureand size, therefore the caulkingcompound is not always in a positionto expel the air pockets fromthe pores during caulking. As a resultsmall bubbles within the jointmay surface during caulking. Toavoid the development of these“air” bubbles, we recommend toolingthe joints using a smooth, slightlyflexible spatula at an angle of45°, expelling from the pores andallowing a perfect joint to developduring cure.For further information pleasecontact your local Sika company.27
