3x Bartoline 1876 PVA Adhesive & Sealer Multi-Purpose Bond Agent Drying 2.5L

Bartoline

Bartoline 1876 Multi Purpose PVA is a high-performance primer and bonding aid for interior use for plastering, as an admixture and for priming porous surfaces for use by the professional user. Bartoline 1876 PVA will also bond most common building materials.DIRECTIONSFor use as an Adhesive: To achieve good adhesion ensure that the surfaces are sound, dry and clean. Join the bonding surfaces together while the PVA is still wet or tacky. Bartoline PVA should be used neat in woodworking applications. Joints should be clamped together to prevent movement until the bond is formed (allow 24 hours to achieve maximum strength). When applying plaster use neat and brush onto the surface prior to plastering. Apply while the PVA is still tacky. For small cement renders combine Bartoline PVA with an equal amount of water and add to the mortar mix. This will improve adhesion and tensile strength of the cured render. For large areas dilute 3 parts Bartoline PVA with 1 part water and brush onto the surface to be repaired. Apply the normal render mix before the emulsion dries.For use as a Primer or Sealer: For sealing porous substrates (old concrete, plaster, plasterboard etc.) dilute 1 part Bartoline PVA with 5 parts water and brush onto surface. This will seal the surface in preparation for tiling or further coating.Minimum solids content: 34%Coverage recommendation: Applications for use vary widely and depend largely upon the porosity and type of substrate concerned. Therefore the following dilutions and volume usage are intended as a guide only:Neat = 6-12 m2/L. Diluted 1:1 = 16-24 m2/L. Diluted 1:3 = 18-36 m2/L. Diluted 1:4 = 24-48 m2/L. Diluted 1:5 = 30-60 m3/L. DRYING TIME (approximate).
