SikaEmaco® P 5000 AP

12 months from production date

Store in a cool and dry area in original packaging and at temperatures below +30 °C. Protect from direct sunlight, heat and moisture.

For steel protection: 2 mm in two layers.

+5 to +35 °C

1.1 L - 1.3 L per 5 kg

(water/powder (w/p) ratio = 0.22 – 0.26)

+5 to +35 °C

~60 min. (+20 °C)

• Second Coat can be applied after approx. 30-90 minutes (at +20°C).

• Repair mortars can be applied by hand after approximately 2 hours (at +20°C) after the application of the second coat.

• For subsequent spray-application of repair mortars the second coat must be left to dry for minimum 8 hours (at +20°C).

For steel protection:

• approx. 80 g/m for rebars with 8 mm diameter

• approx. 180 g/m for rebars with 16 mm diameter

For use as bonding slurry:

• Typically 2 - 3 kg of powder per m² are needed. Approx. 1.8 kg powder yields 1 liter of fresh mortar.

All corrosion and its by-products (loose rust particles, chippings) on the steel reinforcement must be removed from the full circumference of exposed steel reinforcement to be coated. Sandblasting is recommended to clean the steel down to metal, meeting the requirements of ISO 8501-1 / ISO 12944-4 minimum class SA2½. If for logistical reasons this is not possible, vigorous brushing of the metal surface should be carefully and thoroughly carried out to remove all rust (minimum class St 2). Any additional reinforcement must be treated in the same way.

When using SikaEmaco® P 5000 AP as a bond coat on concrete, the surface must be completely clean and structurally sound. Remove deteriorated or contaminated concrete or mortar, e.g. by grit or high-pressure water blasting. Saturate the concrete surface with water but remove excess of water before application with compressed air or rags.

Pour the minimum amount of clean, uncontaminated water into a neat mixing bucket.

Mixing water ratio varies 0.22 to 0.26 litres per kg of powder, depending upon consistency required. Add the SikaEmaco® P 5000 AP powder slowly and mix by hand or with a suitable paddle attached to a powerful, slow speed electric drill (max 400 rpm) until a smooth, thick consistency is achieved. Allow the SikaEmaco® P 5000 AP mix to stand for 5 minutes so that full saturation of re-dispersible polymer can take place. Re-mix briefly before use, until a lump free consistency.

Note: Do not re-temper the mortar by adding extra water. Add water if necessary, but never exceed the maximum water demand!

Do not apply SikaEmaco® P 5000 AP when the temperature is above 35°C or below 5°C or expected to fall below 5°C in the next 24 hours. Do not apply SikaEmaco® P 5000 AP to frozen or frost covered surfaces!

Apply the mixed material in an even layer at least 1 mm thick to the full circumference of the prepared reinforcement using a soft paint brush. When the first coat has hardened sufficiently (after approx. 30-90 minutes), apply a second coat also 1 mm thick. A film thickness of approx. 2 mm should be build up in two coats. It is important that this second layer has sufficiently hardened (depending upon application), before the repair mortar is applied. Repair mortars can be applied by hand after approximately 2 hours (at +20°C). For subsequent spray-application of repair mortars the priming coat must be left to dry for minimum 8 hours (at +20°C).

SikaEmaco® P 5000 AP can be applied as a bonding slurry on concrete substrates. The prepared substrate should be pre-soaked, preferably for 24 hours, but at least 2 hours before applying SikaEmaco® P 5000 AP. Fresh primer should be applied on to the pre-soaked, damp surface by using a suitable brush. Apply the following repair mortar wet-in-wet onto the bonding coat of SikaEmaco® P 5000 AP. Never allow the slurry bond coat to dry out!

Protect from rainfall and strong winds until mortar has finally set.
