Bondsure® BAC-P PET-Type Bituminous Waterproofing Membrane Double-Sided Self

※  Material Features

1. Cost-Effective

Manufactured by patented production technology, can be bonded with unsolidified cement, to completely eliminate water-channeling.

2. Unique Wet-application Technology

The self stick roofing underlayment can be applied on wet or uneven substrate surface. No need of primer, not affected by the weather. Especially during rainy season, the advantage is more prominent when compared with hot-applied membrane.

3. Reliable Bonding of Overlapping Edges

As the peel and stick rubber membrane is self-adhesive type, it's very easy to do the treatment of overlapping areas.

4. Strong Bonding Strength

The sticky waterproof membrane can be bonded tightly to the substrate, if there is local failure on the membrane, water would be confined in a limited area without fluid-channeling, which makes it much easier to repair.

5. Safe & Environmental-friendly

During construction, there is no solvent or fuel involved. Avoiding pollution, fire risks and saving resources as well.

※  Scope of Application

1. Wet Application

2. Hot Application

HOT APPLICATION is composite of rubber asphalt waterproof coating and self-adhesive membrane which is closely bonded with the base layer to form a "skin-type" waterproof system. It is an organic whole with complementary advantages, which can adapt to the deformation and self-healing performance of the base, effectively prevent water channeling and reduce leakage hazards.

 

Substrate Requirements

1) The firmness and strength of the base layer should meet the design requirements.

2) The surface of the base layer should be clean and smooth, and there should be no quality defects such as powdering, sanding, peeling, voids and pits.

3) Remove sundries, greasy dirt, sand, etc. on the surface of the base layer, and the cleaning work must be carried out at any time during the construction.

4) If there is clear water on the base layer, it needs to be cleaned before construction. If the base surface is relatively damp, it needs to be dried with a blower.

 

 

3. Dry Application

 

If the substrate condition can meet with designed and standard requirements, flat, even, dry and without dirties, after covering the base surface with primer, the membranes can be paved directly. Al l pipe fitting should be pre-covered as designed and standard requirements, and to be seal treated. The internal and external corners of substrate wipe to circular. The min radius of internal corners is 50mm and the max radius of external is 20mm. 

 

Make sure the moisture content less than 9% (Dry test: pave 1 ㎡ membrane smoothly on the screed-coat, then check the membrane paved side whether has watermark or not after 3~4 hours, if not, it can be constructed).

 

 

※  Storage and Transport

1. Different types or specifications of self stick roofing membranes should be separated, not mixed.

2. Keep peel and stick bitumen roofing dry and ventilated, protected from the sun or rain.

3. Storage temperature should not be higher than 45 ℃. Pile up the membranes flatwise whose stockpile height should not exceed five layers.

4. Prevent tilt or side pressure during transportation, and cover with felt if necessary.

5. Storage time is at least one year from manufacture date if the self adhesive roofing material is under normal storage condition.
