APPLICATION INSTRUCTIONS
SUBSTRATE QUALITY / PRE-TREATMENT
Ensure the surface is dry, clean, free from dirt, dust and grease or loose material.
Always agitate SikaBond® PVA+ before use.
APPLICATION METHOD / TOOLS
Apply using a brush, roller or spreader, and always use clean water.
General Bonding:
– When used neat, PVA will bond most common building materials providing one surface is porous.
Sealing and priming
• Apply to the clean surface with 1 part PVA to 3 to 6 parts water and allow this to dry.
Bonding Absorbent Surfaces
(Concrete or Plaster):
- Step 1 – Prime the clean surface with 1 part PVA to 3 to 6 parts water and allow this to dry.
- Step 2 – Once primer is dry, apply bonding coat of 1 part PVA and 0.5 to 2 parts water, while the bonding coat is still tacky apply plaster / screed.
Sealing Non-Absorbent Surfaces
(Paint or Tiles):
- Repeat Step 1 above, then paint or tiles etc. may be applied as per manufacturer’s instructions.
Applying Internal Patching Mortars and Screeds:
- Always apply cement renders, screeds or plaster whilst the bonding coat is still tacky. If dry re-apply.
- For bonding new screeds to old, prime clean surface with 1 part PVA diluted with 5 parts water and allow to dry, follow step 1 and 2 under bonding absorbent surfaces above.
- Recommended for internal use only. For external application use SikaBond® Waterproof PVA or SikaBond® SBR+. Not for load bearing applications.
SikaBond PVA+ As a cement admixture
