Jotafloor Damp Bond is a specially formulated two component, epoxy resin based primer used to promote adhesion between Jotafloor products and the parent concrete substrate. Can also be applied directly onto damp green concrete thereby aiding the curing process.
For use primarily as a primer for Jotafloor systems in many situations such as: Kitchens
Factories Car parks Traffic Decks
Warehouses Basements
Manufacturing facilities Industrial Unites
Provides a cost effective method of curing and priming using one product thereby minimising labour costs and down time. It is important to seek technical advice from your local Jotun office on choice of primer and application technique.
*Measured according to ISO 3233:1998 (E)
All concrete damaged by exposure to chemicals, contaminated by any substance or unsound in any way, shall be removed to expose sound concrete.
Cleanliness: Blast cleaning to min. Sa 2 ½ (ISO 8501 1:2007). Roughness: using abrasives suitable to achieve Grade Medium G (50 - 85 µm, Ry5) (ISO 8503-2).
Clean, dry and undamaged compatible primer. Contact your local Jotun office for more information.
Concrete surface preparation by using dust free captive blasting units, grinding equipment, sand blasting or high pressure water jetting is critical to achieving the right surface profile prior to paint application. Please contact your local Jotun office for more information.
Application on green concrete can take place as soon as it is practical to walk on the surface. Damp green concrete can be brushed or subject to light grinding prior to application of the primer.
The coating may be used on other substrates. Please contact your local Jotun office for more information.
The temperature of the substrate should be minimum 15°C and at least 3°C above the dew point of the air. The temperature and the relative humidity should be measured in the vicinity of the substrate. Good ventilation is usually required in confined areas to ensure proper drying. The coating should not be exposed to oil, chemicals or mechanical stress until fully cured.
Mixing 2 parts Comp. A ( base) to be mixed thoroughly with 1 part Jotafloor Damp Bond, Comp. B (curing agent). We strongly recommended no part mixing. Mix and use immediately

1. Recommended data given for product prior to application of Jotafloor Non Slip Aggregate and subsequent over coating with Jotafloor PU Topcoat
The given data must be considered as guidelines only. The actual drying time/times before recoating may be shorter or longer, depending on film thickness, ventilation, humidity, underlying paint system, requirement for early handling and mechanical strength etc. A complete system can be described on a system sheet, where all parameters and special conditions could be included.
