Eco-friendly   Costly to purchase 
Scent similar to latex paint  Require professional services 
Low toxicity and harmless to your health    Possibility of reaction withglues, waxes, and silicones 
Low VOC concentration: approximately 220 g VOC/L  Can stain the woodif they’re not appliedappropriately 
Can be applied without a mask   Resistant to abrasion 
Have aluminum oxide technology   Provide colour to wood floors  
Adapt better to the movements of the wood   

  

Advantages and disadvantages of latex varnishes 

Advantages  Disadvantages 
Dry to the touch after about 2 hours  Costly to purchase 
Eco-friendly  React to moisture 
Scent similar to latex paint  Contain less solid (resin) than oil-based varnishes 
Low toxicity and harmless to your health  Require professional services 
Low toxicity and harmless to your health  Possibility of reaction with glues, waxes, and silicones 
Low VOC concentration: approximately 235 g VOC/L  Much higher price for a water-based urethane varnish 
Can be applied without a mask  Can stain the wood if they’re not applied appropriately 
Preserve the natural colour of the wood  Harder to apply in the summer 
Have an anti-yellowing UV filter   Water-based urethanes can be catalyzed  
Have aluminum oxide technology    
Possibility of remaining in your home during the application   
Don’t contaminate food
