SYMPTOMS |
ISSUE |
SOLUTION |
Did not cure within the expected timeframe |
- Improper temperature/ humidity
- Thinned with improper solvent material, or too much thinner
- Applied too thick
|
- The most common reason is that the product was applied outside of the normal application temperature and humidity range. Wait longer, the varnish will cure.
- Only use the specified solvents with this product. Do not use more solvent than specified. Brushing solvents will slow the rate of the varnish's cure.
- If the product is applied too thick, the solvents in the product take longer to evaporate and the coating to start to cure.
|
Did not cure |
- Surface contamination
- Incompatible solvent used with the varnish
|
- Remove the uncured varnish. Follow the surface preparation instructions with more care and attention to detail. Reapply Lust.
- Only use the solvents that are specified for use with Lust.
|
Peeled away from the substrate
|
- Improper surface preparation
- Not a compatible substrate
- Used solvents that are not compatible with Lust
|
- Poor surface preparation can leave surface contaminants that prevent Lust from bonding to the substrate. Take extreme care when preparing the surface.
- Only use Lust varnish on compatible substrates.
- Only use the solvents that are specified for use with Lust.
- Remove any Lust varnish and start the surface preparation over, while taking more care.
|
Gloss product was not high gloss |
- Thinned too much
- Thinned with a product that is not compatible
- Not enough coats to develop a high-gloss finish
- Moisture or dew settled on the surface before it was fully cured
- Other contamination
|
- Do not over-thin Lust. Thin as little as possible to promote the best gloss.
- Only use the solvents that are specified for use with Lust.
- The gloss will increase with each coat applied. The more coats, the glossier the finish will be.
- Do not apply when high humidity, dew, or rain may be a factor.
- Protect the finish from any other contamination after the product is applied; Lust should be tack free within about an hour, but is still susceptible to certain contaminants for up to 48 hours.
|
Satin product did not leave a satin finish |
- Flattening agent material settled in the can
|
- The flattening agent has a higher density than the rest of the varnish material, and can settle over time. Reach a paint stir stick to the bottom of the can to see if the flattening agent has formed a gel or putty type material on the bottom of the can. Shake or stir the product until there is no sign of the settled flattening agent. The varnish may also go from a deep amber appearance to a little bit more cloudy looking when the flattening agent is mixed back in.
|
Fisheyes when the varnish was applied |
|
- Grease, oil, wax, or other substances that are considered surface contaminants may repel the varnish. Remove the coating, if needed. Follow the procedures to thoroughly clean the surface appropriately before applying more varnish.
|
Matte finish has brush marks and streaking |
- Applied too thickly
- Improper thinning
- Use an appropriate brush for a finish coat
|
- Applying thick coats can deposit too much of the flattening agent, leaving a streaky appearance. Always apply Lust at the specified thickness.
- Always stir the product very thoroughly before applying to have an even distribution of the flattening agent.
- If conditions are not allowing the product to flow as desired, try to thin the product a little more.
- Always use an appropriate brush to promote the best finish. A higher bristle count will promote a smoother finish and less streaking of the flattening agent.
|
White spots in the varnish |
- Moisture emanating from the wood substrate, leaving white spots under the varnish
- If the matte finish product was used, the flattening agent might not have been mixed in thoroughly
- Matte finish used on bare wood, or wood that has not been properly sealed
|
- Wood must be completely dry, ideally less than 10% moisture content. If wood cleaners or teak cleaners are used, wait at least 5-7 days before applying any varnish products.
- When using the satin finish, use the gloss finish material to build sufficient coats. Only use the satin finish product on the final coat.
|
The product skinned over in the can |
- Lid was not closed tightly
- Product was stored for a long period of time without being used
|
- Always close the lid completely after use.
- If the product is going to be stored for a long time between uses, using a product such as Bloxygen® to displace the air in the can first, can help prevent skinning over in the can. Lust has a high concentration of drying agents to promote a short dry time, which can also lead to skinning over in the can if left for too long. The skin can be peeled away to expose good, usable varnish.
