Which sanding sealer to use?
« on: August 13, 2016, 11:23:04 PM »

Hello,


Can anyone recommend a sanding sealer I can use to make the top grain of my birch ply decks look more like a steel finish when painted, I will also be using Halfords spray paint to finish the model so would need it to be compatible with that also so that it doesn't react.


Thanks

One option would be car body filler. Then there should a perfectly flat finish after sanding, and be no compatibility issue with Halfords rattle cans.

I use Rustins sanding sealer and have had no problems with Halfords paint reacting with it

I use Liberon Sanding Sealer. Not always the easiest to get hold of, you usually need a specialist craft or woodworking shop.

Simply use Halfords clear laquer....give it 3 coats rub it down with 180 grit dry to de nib it........3 coats again and simply primer. This will do the same job as sanding sealer and is compatable with your spray cans from Halfords.


This is what I do to seal wood and it works a treat

My penny worth


6 coats of lacquer costs a lot more than a couple of coats of sanding sealer that is specifically designed to fill grain. Halfords lacquer is 6.99 for a small can

Hi ya,   I have always used either Sanding Sealer specifically made for modelling by JP (J Perkins, London) or one made by Deluxe materials - that again is made for the modeller.  I was lead to believe that the commercial sanding sealers e.g. the stuff that is used for woodworking and you buy from DIY contains a small amount of wax which can be a problem for us modellers - the other thing is I have also used when I have ran out of sand n sealer - Deluxe Eze Kote resin.

Q. What is a sanding sealer


A. "sanding sealer can be used on bare, unstained floors, doors, furniture and cabinets prior to applying either an oil-based or a water-based clear finish. It is designed as a base coat that will dry quickly, seal the pores, and sand easily with fine sandpaper to create an ultra-smooth foundation."

I have used both Shellac Sanding Sealer and Cellulose based Sanding sealer, both have worked without adverse reactions. The Shellac version is slower drying and a bit 'wetter', so can run about awkward shaped items, pooling before drying. The cellulose type is very quick drying. On a warm day and with a 36 inch boat, you can start at one end, work your way round the model, by the time you get back where you started, it will be dry and you can put another coat on.
I have also found that a pretty standard brush on all purpose primer from places like B&Q, will seal your grain and provide a pretty decent base coat. Even better if it can be rollered on. I have found it can be wet and dry sanded (lightly!) after about 45 minutes, to a very smooth finish.
Tried all three, would recommend all three, prefer the Cellulose option, just...

Hi sorry I've missed all these replies by not checking back here but thanks to everyone that put suggestions forward.
In the end I went with Deluxe ezekote resin which although probably not the cheapest has done a brilliant job hiding the surface grain and I've had no problems using Halfords spray cans over it.
