FAQs
Can I use Bartoline PVA for exterior projects?
No, the Bartoline 1876 Multi Purpose PVA is specifically designed for interior use only.
How do I dilute the PVA for priming porous surfaces?
For sealing porous substrates like old concrete or plaster, dilute 1 part Bartoline PVA with 5 parts water and brush onto the surface.
What is the drying time for the bond?
The drying time is approximate, but allow 24 hours for the bond to achieve maximum strength in woodworking applications.
Can I mix Bartoline PVA with paint?
This product is not designed as a paint additive. It is intended as a primer, sealer, adhesive, or admixture for plastering and cement work.
How do I clean up tools after using Bartoline PVA?
Clean all tools and brushes with water immediately after use, before the PVA has dried.
What is the minimum solids content?
The minimum solids content for Bartoline 1876 Multi Purpose PVA is 34%.
Is this product suitable for bonding wallpaper?
While it's a strong adhesive, it's primarily intended for more robust applications like woodworking, plastering, and rendering. Dedicated wallpaper adhesives are generally recommended for wallpaper.
Troubleshooting
PVA not adhering well
Ensure the surface was properly prepared (sound, dry, clean, free of dust and grease) before application. If used as an admixture, ensure correct dilution ratios were followed.
Bonding surfaces are not holding
Verify that surfaces were joined while the PVA was still wet or tacky. Ensure joints were adequately clamped and allowed the full 24 hours to achieve maximum strength.
Cracking or peeling after plastering/rendering
Check if the PVA primer was applied correctly and allowed to become tacky before plastering. For render, ensure the correct dilution of PVA was added to the mix or applied to the surface beforehand as recommended.
White residue after drying
This can occur if the PVA was applied too thickly or not allowed to dry fully. For primers, ensure the recommended dilution was used. For adhesives, ensure excess was wiped away before drying.
Pros and Cons
Pros
- Versatile across multiple applications (adhesive, primer, sealer, admixture).
- Significantly improves adhesion and strength of various materials.
- Effectively primes and seals porous surfaces for better finishing.
- Suitable for both small-scale repairs and larger plastering jobs.
- Professional-grade performance for demanding tasks.
Cons
- Strictly for interior use only.
- Requires specific dilution ratios for different applications, necessitating careful measurement.
- Drying time can vary, and surfaces need to be kept undisturbed during the curing process.
- May not be suitable for all types of plastics or non-porous materials without proper surface preparation.
Setup, Compatibility & Care
Setup: The Bartoline 1876 Multi Purpose PVA is ready to use as supplied for certain applications (e.g., neat for woodworking adhesion). However, for priming, sealing, or as a render admixture, it requires dilution with clean water according to the specific application guide. Ensure surfaces to be bonded, primed, or sealed are sound, dry, and free from dust or grease.
Compatibility: This PVA is compatible with most common building materials including plaster, concrete, wood, and plasterboard for interior applications. It is designed to be used *before* plastering, tiling, or coating.
Care: Store the product in its original container in a cool, dry place, away from direct sunlight and frost. Keep the container tightly sealed when not in use. Clean all tools and brushes with water immediately after use. Once dry, the PVA is difficult to remove.
