The difference between solvent based and water based coating?




Water based coating




  • Can be cleaned from brushes easily with water only.



  • It evaporates much less harmful agents such as VOC to the environment and to you.



  • It does not emit strong odour while working.



  • Much quicker drying times (normally within 1-2 hours per coat to touch dry).




Solvent based




  • It needs solvents such as white spirit to clean the     spill and the coating on your brush.



  • It evaporates VOC while working which is     hazardous.



  • It emits strong odour while working.



  • Drying times tend to be long.






Why sanding the wood?




The reason of sanding wood



  • Achieve a nice smooth finish, because by sanding you are removing imperfections on the bare wood such as splinter or stain (imperfection will be magnified when the final coat is applied.



  • Strengthen the bonding betweenthe coating and wood, because through sanding you sand out the softer layer, thetougher layer left, this develops some small and rough ridges on the wood forthe paint to stick on.




The different grits of sanding tools




  • 40 – 80 (Coarse grit) – rough sanding and removing stock quick and efficiently.



  • 100 – 150 (medium grit) – fine tune the last coarse grit sanding; and removing scratches left by coarser grits.



  • 180 – 220 (finer grit) –removing scratches left by coarser grits on unfinished wood; light sanding between coats of paint to increase the next coat’s adhesiveness and smoothness.




How much should you sand?




  • Do inspection! After removing dust caused by sanding, look at the wood in a low-angle reflected light – e.g. from a window or a light, see if the wood is actually smoothened.





How to achieve the best result of my wood finish– smoothest finish?




Give weight to wood preparation




  • Good paint will never make up for a poor prep.


  • Thoroughly clean, sand, and prime your surface (if necessary) before painting.



  • Constantly inspect the performance of your sanding work.




Control the thickness of your coating




  • How to control? :  To thin the coating, simply damp your brush with a little water before loading your brush with pain, once your brush gets dried, do the cycle again. (Warning: do not over dilute coating and directly dilute the whole can with water!).



  • Thinner paint smoothens the momentum of each brush stroke (i.e. less effort) and it helps hide brush marks (i.e. smoother finish).



  • Thick and gloppy paint will make your finish look full and rich.



  • Tips: Wood coatings’ thickness vary, please check each coating and evaluate the dilutability (e.g. Ronseal interior varnish itself is thin enough for a smooth finish).




Put it on and leave it alone




  • After putting the paint on, ensure whether the finish has the level smoothness you really want.



  • Once finish is confirmed, please do not go back and work the paint relentlessly and do not touch it.



  • Try avoid drying your finish in a dusty area.



  • Do not leave excess paint on the wood, it will leave blotches and uneven surfaces.




Multi surface painting tips




  • When working on a cube-like or other difficult objects, try plan the first one/ few surface(s) to paint, and paint the next one(s) after the previous one(s) dried.




Always stir the can before using the paint




  • Do not shake the can, it will create air bubbles which will get transferred to your wood.




Buy a good brush




  • A good brush means efficiency in transporting paint from the can to your wood (less effort) , a good brush will have a major impact on how the finish looks when it dries (smoother finish).





The difference between “satin” and “matt” and “gloss”?




  • Gloss – highly shiny glossy finish which is very reflective


  • Satin (aka semi gloss) – soft sheen paper which is half way between gloss and matt


  • Matt – totally flat finish with no sheen or reflective properties




How to distinguish between coated and uncoated wood?




Coated vs. uncoated?


In general, uncoated wood has a rough and natural texture, less glossy, deeper mark occurs when pressing your nail on the wood.



However, some wood coatings may have asimilar effect with the natural wood texture. 





How to up-cycle coated wooden furniture?



For valuable antique wooden furniture:




  • It requires special treatment because of the dignity of their age. Therefore,this answer is not applicable to your case




For ordinary used wooden furniture:




  • Useour primer, after sanding your furniture’s uneven surface, to cover up theoriginal color, this creates a basecoat for the next coat (your favorite color)to stick on. This is due to our special formulated primer could tick on many“already coated” or difficult surfaces.




The differences between outdoor (exterior) and indoor (interior) coating ?



Interior paint:




  • Additives provide consistent coverage.


  • Easier to remove.


  • Usually more resistant to splatters and scuffs.


  • Responds well to cleaning.




Exterior paint:




  • Stands up to wear fromtemperature and moisture


  • Anti-fade UV protection for constant sunlight exposure.


  • Additional fungicides and pesticides.


  • Mildew prevention.


  • Durability.


  • Extra pigment and resin.
