Slasto and natural stone sealer

Application of Gripseal interior & exterior slasto & natural stone sealer

Step 1:

Ensure that the surface is free of dust, dirt, oil, grease and or solvents.
Check that the surface is sufficiently porous by doing the following quick test:

  1. Drop a droplet of water onto the surface.
  2. If in 20-25 seconds the water droplet has been absorbed, the surface is sufficiently porous for sealing ie: the surfaceporosity is 6% or greater.
  3. If the water droplet takes 25-45 seconds before it is absorbed, the surface can still be sealed, however it is recommended that the first coat be diluted 50/50 with clean tap water.

Step 2:

Use Gripseal sponge brush, paint brush or spray gun to apply.
Do not apply in direct sunlight.
For best results apply 2 thin, even coats.
On bricks with a low porosity, the thinner the coats the better.
Allow 20 minutes between coats and 12 hours for sealant to cure completely.

Step 3:

Clean applicators with clean water directly after application.
