1 Foreground code is running, interrupts are enabled. 2  Interrupt event sends an interrupt request to the CPU. 3  After completing the current instruction(s), the CPU begins the interrupt response. 4  automatically saves current program counter. 5  automatically saves some status (depending on CPU).
Impregnator or penetrating sealers are designed to penetrate below the. surface of the stone and either deposit solid particles in the pores of the stone, or coat the individual minerals below the surface. Penetrating. sealers work by restricting water, oil and dirt from entering the stone or tile.
Most weeks I receive calls from people asking how to remove a sealer residue. Sealer residues occur when an impregnating sealer is incorrectly applied. Impregnating sealers (or penetrating sealers as they are sometimes known) are intended to be in or below the surface of the stone rather than âonâ it.ost weeks I receive calls from people asking how to remove a sealer residue.
