Sikadur® PF

Epoxy resin and special fillers

24 months from date of production

Store in original, unopened, sealed and undamaged packaging in dry condition at temperatures between +5 °C and +30 °C. Protect from direct sun light and moisture.

~1.75 kg/l (mixed resin at +23 °C)

Component A : Comp. B = 2 : 1 (by weight and volume)

Maximum 3 mm in one single layer

 +5 °C min. / +45 °C max.

Beware of condensation.

Substrate temperature during application must be at least 3 °C above dew point.

 +5 °C min. / +45 °C max.

~45 min. (+25 °C)

*200 g

The potlife begins when the resin and hardener are mixed. It is shorter at high temperatures and longer at low temperatures. The greater the quantity mixed, the shorter the potlife. To obtain longer workability at high temperatures, the mixed adhesive may be divided into portions. Another method is to chill components A and B before mixing them (not below +5 °C).

Sikadur® PF can be over coated with various Sikafloor®, Sikadur® and Sikagard® resins after 12 hours and not later than 24 hours at +30 °C.

Sikadur® PF is fully cured after 7-14 days, depending of ambient temperature.

This figure is theoretical and does not include for any additional material required due to surface porosity, surface profile, variations in level or wastage etc.

• The substrate must be sound and of sufficient compressive strength (minimum 25 N/mm²) with a minimum pull off strength of 1.5 N/mm².
• The substrate must be clean and free of all contaminants such as dirt, oil, grease, coatings and surface treatments, etc..
• Concrete substrates must be prepared mechanically using abrasive blast cleaning or scarifying equipment to remove cement laitance and achieve an open textured surface.
• Weak concrete must be removed and surface defects such as blow holes and voids must be fully exposed.
• All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush or vacuum.

Mix components (A and B) together for at least 3 minutes with a mixing paddle attached to a slow speed electric drill (maximum 400 rpm) until the material becomes smooth in consistency and an even in colour of the mixture is obtained. Avoid aeration while mixing. Sikadur® PF is supplied ready for use and only has to be thoroughly stirred.

Ensure that the epoxy is forced well into the repair surface. Once the repair has been completed the surface can be finished with a steel float or trowel to achieve the desired effect. For corner repairs, it may be necessary to install formwork to one side of the void for easier application.

Clean all tools and application equipment with Sika® Colma Cleaner immediately after use. Hardened / cured material can only be removed by mechanical means.
