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.
