Dupoxy Prime SFD

• Surface Preparation : Thorough surface preparation is vital. For best results Dubond recommends mechanic al preparation techniques. (For example, mechanical scarifying, grit-blasting, sand blasting).
  For flooring and tanking works, care must be taken to ensure that the substrate does not suffer from rising dampness. If such conditions exist, consult Dubond.
• New concrete floors : Should be at least 28 days old or have a moisture content of less than 5% before proceeding with epoxy application. Laitance and deposits on new concrete floors are best removed by light grit blasting, mechanical scrabbling or grinding.On smaller areas through etching using Reebaklens may be considered. After etching the dloor, it should be thoroughly washed with clear water and then allowed to dry.
• Old concrete floors : Again, mechanical cleaning methods are strongly recommended on old concrete floor, particularly where heavy contamination by oil and grease has occured or existing coating are present. These may well have been absorbed several millimeters deep into the concrete. To ensure good adhesion all contamination should be removed and the surface thoroughly cleaned of all dust and loose debris. A through detergent wash is also recommended followed by cleaning with water and mopping it off to dry state
• Mixing : Add the entire contents of the hardener tin to the base and mix thoroughly for 3 min. until homogeneous, using a slow speed drill (400-500 rpm) fitted with a suitable mixing paddle.
• Application : Once mixed the primer should be applied immediately in a thin continuous film to the clean prepared surface. Work the primer into the surface using a stiff brush or roller. Excess application and pudding should be avoided. On porous surfaces Dupoxy Prime SFD will be absorbed very quickly leaving characteristics coloured dry patches. It is recommended that a second priming coat be applied to these dry areas. This not only helps to ensure good adhesion but also prevents air release from the porous substrate which may cause bubbles in the final epoxy topping later.
  For Dupoxy SL applications, leave the Dupoxy Prime SFD to dry overnight.

Available in 1 & 5 kg packs.
