Excellent resistance to a wide range of chemicals.

Refer to PurCem Chemical resistance document.

Only mix full kits of Sikafloor 33 PurCem and ensure the correct amount of PurCem accelerator is added as per the below guide.

5.2kg kit: A+B+C+Pigment

Part A 1.3kg   Part B 1.9kg   Part C 1.6 kg Pigment 0.4kg

PurCem Accelerator: Required for installation temperature below 20 degrees C to achieve similar curing to Sikafloor 31PurCem- please refer to the below Sikafloor PurCem Accelerator Addition Guide:

Temp 15 Degrees C - 200mls/5.2kg kit
Temp 10 Degrees C -  250mls/5.2kg kit

Do not apply below 10 degrees C or above 30 degrees C

Maximum RH - 85%

Apply on substrates below 10% surface moisture  ( See Sikafloor HB-22 PurCem TDS )

15-20 minutes at 20 degrees C

Foot traffic -             24hrs ( at 20 degrees C)

Vehicular traffic           36 h  ( at 20degrees C)

Full chemical cure       5 days (at 20 degrees C)

16h min / 48 h max  (at 20 degrees C)

As a coating for Sikafloor HB-22 Textured system   - approx 1.8 - 2.2 M2 per litre per coat (6.5 - 8.0 m2 per 3.71L kit )

For optimum results;

Apply with a centre shafted roller frame at least 350mm in width.

Roller knap length of 15mm minimum

Mixing will be affected by temperature; condition materials for use to 18 - 15 Degrees C.

1. Add pigment to part A, stir for for approximately 15 seconds.

2. Add component B,  mix for approx 30 seconds.

3. While mixing, add component C within 15 seconds.

4. Further mix for 2 minutes until the mixture is homogeneous and the pigment is uniformly dispersed.

5. If required  add the required amount of Sikafloor PurCem accelerator and mix for a further 30 seconds.

Use material immediately

Note: Failure to follow the above may result in uneven gloss and or colour in the finished product

Apply evenly with correct roller and roller sleeves as decribed in Equipment section.

For best results on textured HB-22 systems, pour the product onto the surface in lines and apply out with a rubber tipped squeegee.

"Lay off" the excess with the rollers to create and even distribution in the texture.

 Performing this then at a right angle will futher even out the product distribution .

Note:

Mixing buckets should be discarded for new ones approx every 3-4 mixes at 20 degrees C.

Roller sleeves should be dicarded for new ones approx every 30 minutes at 20 degrees C.

Failure to do this will likely result in uneven texture and sheen in the finished product.

For lighter colours and or being applied on Broadcast B1 texture, consideration should be given to a second coat to ensure full colour distrbution.
