I like to know if sealing a new blade with polyurethane sealer , changes the playing characteristics of the blade.I just bought a 729 bomb and before I seal it with sealer, I would like your opinions and experience about this topic.

Hi Eddie,

The sealer will make the blade feel a bit harder and slightly heavier.  It is good if you are taking off rubbers regularly.  As most rubbers are put on and left for a while now there probably isn't a lot of reason for sealing them.

Hi Alois,

Thanks for your advice.  There are a lot said on the forums about sealing the blade but hardly anything about the effects of sealant on the playing characteristics of the blade/rubber.  I got a Donic Baracuda and the 729 snipe and I will glue them on the Bomb without sealant. Just have to be careful when time come to change rubbers ( many moons away), making sure I don't tare a bit of the wood off the blade.

Still, I hope to hear from guys who used sealant on the blades and learn from their experience.

ive recently decided to seal any blade that i buy. i have been playing about 4 years. and ive used a lot of blades and rubbers through experimenting over this time. quite often when changing rubbers ive removed splints of wood with the rubbers, its quite easily done, especially when you use a lot of glue (when using these new voc free waterbased type). it helps when i use only a thin layer of glue now, and thats all you need with these new glues, and it helps to dry quicker, but especially when you put a thick layer on you can remove wood from the blade as these glues are very strong. since sealing the blades this eliminates the problem and doesnt change the performance much at all. if anything it increases the speed, but by such a small amount that you adjust to it within the first session anyway. its worth doing to protect the blade especially if its an expensive one.

I've destroyed a blade once with a very flimsy balsa top ply.  Considering how expensive blades are, I would argue blade sealing makes sense (unless you have a blade that you know has a very solid top ply which won't come off with a lot of rubber changes...or unless you never change rubbers...as for me, I am an EJ, so I change rubbers every couple of months!)

hi ji-soo, i used to change rubbers a lot, but now am sticking to xiom they are fantastic, well worth the money for the quality, ive got omega 4 euro on forehand, and vega europe on backhand.
