Abstract: A representative masking stack having a length and width includes a plurality of masking apparatuses. Each masking apparatus is stacked on top of each other such that the stacked plurality of masking apparatuses have an angled side to easily grasp the edge and remove each masking apparatus from the stack. Each masking apparatus includes polymer coatings on top and bottom sides of the masking apparatus. The masking stack further includes adhesive being applied on the bottom side of each masking apparatus, the adhesive being an acrylic or water based emulsification adhesive formula.

Abstract: Disclosed are apparatuses and methods for a masking stick that facilitates painting a household. In one embodiment, a masking stick includes a rigid backing layer having rigidity to maintain a substantially straight line without external force and flexibility to flow with irregularities or curves on an edge of a painting surface to be protected. The masking stick further includes an adhesive layer having adhesive that is placed on a top surface of the rigid backing layer. The adhesive is strong enough to hold the rigid backing layer securely, but can be easily removed without causing damage to the painting surface. The adhesive layer covers at least a portion of rigid backing layer. A method for masking a painting surface is provided herein using the masking stick as mentioned above.

Abstract: The present disclosures are apparatus and methods for driving a screw into a workpiece using a nail gun. In one embodiment, a screw can be driven into a workpiece using a nail gun such that a head of the screw is embedded to the workpiece. In a preferred embodiment, the screw comprises a point section that has a point with a tip angle of approximately 35-37°. The point section is coupled to a thread section. The thread section has threads along the thread section in which the beginning of the first thread is fully formed adjacent to the point section. The thread further has thread having a thread angle of approximately 60-63°. A head section is coupled to the thread section and the head section has a frustoconical head. The head has at least one nib on the side of the head. The frustoconical head and the nib on the side of the head enable the screw to withstand the operating pressure of the nail gun.
