After with expensive emulsioni paint face Qi Dai is used for priming paint, metope becomes such, by

Coating suit, it is one bottom double has form a complete set 3 pails commonly, because metope besmears the craft that brushs emulsioni paint asks,this is, brush a priming paint namely, two levels lacquer, it is such configuration so. But some construction group, to save cost, direct besmear brushs the face paint that installs with tun 3 times. When owner demur, the explanation says face lacquer is more expensive than priming paint, and the effect is better.

Is the thing really such?

That priming paint has what effect after all, whether can be face lacquer replaced?

1, cover action

Metope be bored with child layer construction is finished, color of metope of hard to avoid can have the case with abhorrent depth, if pure the lacquer that use a face, may final metope can have depth abhorrent, appear piebald problem. And priming paint can have original impression cover, make impression color even, after present Qi Tu is brushed twice, the color of metope can keep consistent.

2, fight alkaline action

Cement is alkalescent, we often mention the waterproof dirt that uses child, also be alkalescent. When indoor achieve a certain specific requirement, can appear return alkaline phenomenon. We often see be being written above priming paint fight alkaline priming paint, if brush,go up priming paint, can rise to close action, alleviate thereby the happening of this kind of circumstance.

3, raise face lacquer to add exert oneself

Priming paint serves as be bored with child the medium among lacquer of layer knead dough, need and both and effective union, this function is similar to the action of interfacial agent, make the union of face lacquer more firm. In priming paint, contain taller latex, adherent force is stronger, can raise the adhesion of emulsioni paint film and metope. Appear not easily desquamate phenomenon.

4, increase Qi Feng to be spent completely

Besmearing the adherent power of face lacquer can enhance when brushing priming paint, what still can increase face lacquer is plump degree, face lacquer can be compared it seems that did not go up when priming paint more beautiful, return the dosage that can reduce face lacquer so. Still have even if it is some cheaper that priming paint price is met relatively, you know if use priming paint,still can reduce besmear to brush cost.

The worker replaces priming paint with more expensive face lacquer, what because of them some use is the tun outfit coating with inferior value, whitewash the wall in the process, can brush quantity circumstance according to besmear, after adding water to undertake dilute, the result that as it happens uses, the surface looks, seeming is cost tall, be equal to the cost that saved priming paint actually.

So, when besmear of the metope in husband brushs paint, must beg one bottom two sides, and the specification that should go up according to coating product, check the scale of add water, future trouble is otherwise boundless!
