Applying a waterproofing substrate conditioner.

Product: Bondall Epoxy Prep Surface Conditioner

Surface Preparation:

Careful surface preparation prior to the application of any coating system is the key to a successful job, longevity and per- formance. All surfaces to be coated must be clean and sound. Remove all loose and flaking material from previously coated surfaces. This can be achieved by using a wire brush or by the use of a high-pressure water jet. In situations where moss, mould or mildew is present, remove all loose particles with a stiff brush. Apply Bondall Moss and Mould Terminator and leave for 24 hours. Rinse well by using running water and stiff broom/brush or by using a high-pressure water jet.

New Concrete: On new concrete surfaces, it is imperative that all laitance and/or contaminants are removed that may affect adhesion of the Bondall Epoxy Prep.

Where surface may be contaminated with oil, use Bondall Driveway Degreaser and a stiff brush followed by a rinse with clean water or use a high-pressure water jet.

Mixing Directions:

Bondall Epoxy Prep is supplied in two parts; a Resin part and a Hardener part.

Each part (Resin and Hardener) must be mixed for at least two minutes before use (clean mixing tool prior to mixing next component to avoid contamination and possible reaction between two components).

Pour equal volumes of Resin and Hardener into a clean container.

Thoroughly mix the two components until a homogenous blend is obtained. Mix continuously for 5 minutes using a broad flat paddle by hand or 3 minutes using a mechanical mixer. Avoid aeration – as mixing too fast may entrap air into mix, which may lead to pin holes in the coating.

Allow to stand for between 5-10 minutes before use if temperature is above 20ºC, or, between 10-20 minutes before use if temperature is below 20ºC. The hotter the temperature the shorter the reaction or its induction time, and is critical for the product to work properly. Bondall Epoxy Prep is now ready for use.

Pot Life:

Pot life is very dependent on the temperature of the resin and hardener at the time of mixing. Keep the product out of direct heat and sun and keep it as cool as possible to extend the useful working time. The typical pot life of Bondall Epoxy Prep is as follows:

2 hours at 25ºC/50% relative humidity or shorter. 1 hour at 35ºC/50% relative humidity. Use the product within the time. You will notice a difference in the consistency of the product once its effective working time is reached.

DO NOT APPLY AFTER THIS TIME EVEN IF THE PRODUCT LOOKS SATISFACTORY- IT WILL HAVE TO BE DISCARDED. SO, ONLY MIX ENOUGH FOR IMMEDIATE USE.

Application:

Ensure surface is damp or dampen thoroughly with clean water prior to applying first coat. It is recommended to wet the surface of dry concrete and porous substrates with a mist of water prior to application. Not dampening down dry surfaces will result in the first coat pin-holing.

Apply good thick coats using brush or roller. (Conventional spray methods can be use; however we would not recommend using spraying methods for the handyman)

RECOAT AND CURING TIMES:

Recoating can normally take place after no less than 4 hours at 25ºC/50% relative humidity. Overnight if it is cold.

Apply Bondall Aquatite, Pondtite or Terratite and other conventional paint systems or toppings after at least 8 hours or the next day.

Thinning

Not recommended.

Clean Up

Equipment can be cleaned immediately after use with warm soapy water. When using Bondall Epoxy Prep it is easier to use disposable brushes and roller covers than cleaning up after the job is completed. If good quality brushes or roller covers are used, wash thoroughly in warm soapy water and finally rinse in clean water. Always dispose empty packaging in a responsible manner and according to local regulations. Please do not pour washings down sink, drains or waterways.
